This chapter explains the fundamental concepts involved in Oracle Secure Backup backup and restore operations.
File system data can be defined as the collection of files and file management structures on physical or logical storage. In a differential incremental backup, Oracle Secure Backup back up files modified since the most recent incremental backup at the same or lower level (0-9). A dataset file defines the file system data that Oracle Secure Backup should include in and exclude from a backup. You can find several sample dataset files in the samples subdirectory of the Oracle Secure Backup home. With either obtool or the Web tool, you can execute commands to manage dataset files and directories.
In backups of this type, you instruct Oracle Secure Backup to make backups according to a backup schedule, which specifies the datasets for the backup. In backups of this type, you instruct Oracle Secure Backup to perform an ad hoc or one-time-only backup of the specified data. As shown in Figure 2-3, the execution of scheduled backup jobs depends on whether a backup window exists in which the jobs can run.
A single backup window can apply to all days of the week or only to specific days or dates. When you use the Web tool or the backup command in obtool to initiate an on-demand backup, the backup runs in unprivileged or privileged mode.
If you create a scheduled backup job, then it runs with the privileges of the Oracle Secure Backup scheduler, that is, as root on Linux and UNIX and as Local System on Windows. If a file system backup fails due to an unexpected event like a network failure, power outage, unexpected system shutdown, tape media error, and so on, then Oracle Secure Backup must usually restart the backup from the beginning. The backup image is saved to a tape drive controlled by a server that uses NDMP version 3 or later.
A checkpoint is a collection of state information that describes a midpoint in a backup and how to restart from it. At the beginning of each backup job, Oracle Secure Backup automatically determines whether the backup can be restarted from a midpoint.
When considering jobs to run, the Oracle Secure Backup scheduler takes note of restartable jobs that were interrupted before completing.
As explained in "Administrative Data", the administrative server maintains a catalog in which it stores metadata relating to backup and restore operations for the administrative domain. The Oracle Secure Backup catalog is integrated to share backup metadata with RMAN, but is separate from the RMAN recovery catalog.
When Oracle Secure Backup performs a file system backup or a database backup through the SBT interface (see "Database Backups"), it records the name and attributes of the objects it backs up. Oracle Secure Backup maintains a discrete backup catalog for every client in the administrative domain. To specify backups that you want to restore, you can use obtool or the Web tool to browse the contents of any client's backup catalog, providing you have necessary permissions. When you browse the catalog, Oracle Secure Backup presents the data in the form of a file system tree as it appeared on the client from which the data was saved.
The Oracle Secure Backup catalog contains a record of each file system object saved in each backup.
Directory contents change over time; in fact, the very existence of directories is transient. Oracle Secure Backup provides two means to control how time affects the data you select when browsing backup catalogs: the data selector and the view mode. When you browse a backup catalog to select data to restore, you can choose specific instances of backed up data by using one of the data selectors shown in Table 2-1. Shows the file system object as it existed in a backup no later than the given date and time. When applied to a file system object, a data selector yields the identity of zero or more backup image sections in which the file system object is stored. When you browse a directory in inclusive mode, Oracle Secure Backup displays the name of every file system object backed up from the directory. When you browse a directory in exact mode, you display only the contents of a directory identified by the data selector.
Restoring to the file system with Oracle Secure Backup is essentially the reverse of backing up to the file system. Whereas file system backups are either scheduled or on-demand (see "Scheduled and On-Demand Backups"), all restore operations are on-demand. Whereas some file system backups are restartable (see "Restartable Backups"), no restore operations are restartable. File system backups use datasets to specify data (see "Backup Datasets"), whereas restore operations use one of the methods described in the following section. In this type of restore operation, you browse the catalog for the file system objects to be restored. In this type of restore operation, you must have independent knowledge of the secondary storage location (volume ID and backup image file number) of a backup.
You can use the obtar command-line interface to operate directly on tape drives, outside the purview of the Oracle Secure Backup scheduler.
The backup of an Oracle database performed with RMAN results in a backup set, which is a logical grouping of backup pieces. When you use Oracle Secure Backup to store database backups on tape, each backup piece is created as one backup image. Oracle Secure Backup can mix RMAN backup pieces and file system backup sections within the same volume set and even on the same volume. Oracle Secure Backup uses information encapsulated in database backup storage selectors to interact with RMAN when performing backup and restore operations. Database backup storage selectors contain backup and restore attributes that describe an Oracle database. When performing an Oracle database backup to devices and media managed by Oracle Secure Backup, RMAN passes the database name, content type, and copy number to Oracle Secure Backup. Restore operations that you initiate through RMAN are called Oracle Database restore operations. The scheduler policies, which are described in "Defaults and Policies", determine how the scheduler handles backup and restore jobs. Figure 2-5 shows the process by which a user can create an on-demand backup or restore job.
Oracle Secure Backup maintains a queue of backup and restore requests in the user's Web tool or obtool session. The user sends the backup request to the scheduler (obscheduled) running on the administrative server. When a user sends a file system backup or restore request to the Oracle Secure Backup scheduler, the request becomes a job. This section provides a more detailed explanation of how on-demand and scheduled file system backup and restore jobs are created. At the beginning of the day, Oracle Secure Backup inspects the triggers defined in each backup schedule. Each time you create an on-demand backup request and then use the Go button or the obtool backup --go command to send your request to the scheduler, Oracle Secure Backup creates a dataset job.
At the scheduled start time for a dataset job, Oracle Secure Backup reads the dataset and then creates one subordinate job for each host it includes. Each time you explicitly request that Oracle Secure Backup restore data and then use the Go button or the obtool restore --go command to send your request to the scheduler, Oracle Secure Backup creates a restore job for each backup image that must be read to initiate the restore operation.
If Oracle Secure Backup creates multiple jobs to satisfy one restore request, then it marks each job except the first as dependent on the success of the previous job.
After the earliest time to execute a job has arrived, the foremost decision criterion that the scheduler uses to execute a job is the user-assigned schedule priority.
A job summary is a text file report produced by Oracle Secure Backup that describes the status of selected file system backup and restore jobs. You can create a job summary schedule, which enables Oracle Secure Backup to generate multiple summary reports, each covering different time periods or activities. Oracle Secure Backup maintains information about tape libraries and tape drives so that you can use them for local and network backup and restore operations.
A tape drive is a device that uses precisely-controlled motors to wind a tape from one reel to the other. A tape library is a robotic storage device that accepts SCSI commands to move media between storage locations and tape drives. A library contains one or more tape drives, a number of slots to hold tape cartridges, and an automated method for loading tapes.
Oracle Secure Backup automates the management of tape libraries, thereby enabling efficient and reliable use of their capabilities. When you add a tape library to your administrative domain, the device is configured in automount mode by default. A barcode is a symbol code that is physically applied to volumes for identification purposes. Oracle Secure Backup checks for cleaning requirements when a tape is loaded into or unloaded from a tape drive.
As shown in Figure 2-6, a library consists of a set of addressable elements, each of which can contain a tape or can be used to move a tape. This element represents the robotics mechanism used to move media between other elements in the library.
Oracle Secure Backup refers to elements by their abbreviation (mte, se, iee, or dte) followed by the number of the element, for example, se5, iee2, dte1.
If you manually place volumes into library storage elements, then use the insertvol command to notify Oracle Secure Backup of these volumes, their locations and their properties.
You can use the loadvol command to instruct the tape library to load a volume from a storage element into a tape drive in preparation for a backup. You can use the movevol command to move a volume from one storage element to another storage element. Each tape device is uniquely identified within Oracle Secure Backup by a user-defined name.
Oracle Secure Backup distinguishes a device and the means by which the device is connected to a host.
SAN-attached devices often have multiple attachments, one for each host with local access to the device through its Fibre Channel interface. Devices such as certain Quantum and SpectraLogic tape libraries appear to be connected directly to an Ethernet LAN segment and accessed through NDMP. For NDMP servers that run version 2, other data may be required to define SCSI parameters needed to access the device. To understand Oracle Secure Backup, you need to understand the relationship between the physical backup files and the media on which those files are stored.
Figure 2-8 provides a graphical illustration of how a volume set is related to a media family.
A volume set is a logical grouping of one or more physical volumes spanned by a backup image. When you back up files with Oracle Secure Backup, you generate a volume set that has some common characteristics defined by the corresponding media family associated with your backup.
Backup images are unique identified in the Oracle Secure Backup catalog by their backup IDs.
Example 2-3 shows output from the lssection command for the backup section belonging to the backup shown in Example 2-2. A label contains data that Oracle Secure Backup uses to identify a volume or a backup image.
Backup images and volume labels, as well as the special "End of Data" and "End of Volume" labels, share a common format and include both volume and backup image data. When a label is displayed, volume-related information is displayed with the header "Volume label" and backup image-related information is displayed with the header "Backup Image label." These are actually different parts of a single label. For volumes generated by the Oracle Secure Backup scheduling system, you might see entries such as media family and volume expiration.
As shown in Figure 2-10, when Oracle Secure Backup writes multiple backup images on a volume, it places a tape file mark after each backup image. After you create a backup image, Oracle Secure Backup positions the volume just before the EOD label.
Each volume in a volume set has a volume sequence number that is one greater than the sequence number of the previous volume. If a backup image extends beyond the end of one volume and continues onto a subsequent volume, then Oracle Secure Backup ends the first volume with a special EOV label. A sequence number, which is recorded in the volume label, indicates the order of volumes in a volume set. A section number, which is recorded in the volume label, indicates the order of the parts of a backup image that spans multiple volumes.
A partial volume label for the first backup image could look like the one shown in Example 2-6. The partial volume label for the first section of the second backup image could look like the one shown in Example 2-7. The partial volume label for the second section of the second backup image could look like the one shown in Example 2-8. The partial volume label for the second section of the second backup image could look like the one shown in Example 2-9.
The volume ID consists of a fixed portion, usually the name of a media family, followed by a sequence number assigned and updated by Oracle Secure Backup.
A media family can have either of the following mutually exclusive volume expiration policies: content-managed, which is the default, or time-managed.
Although a volume may be unexpired and have unused tape remaining, Oracle Secure Backup will not write to a volume whose sequence number is lower than the most recent volume sequence number for the media family.
The beginning of the write window is the time at which Oracle Secure Backup first writes to a volume in the volume set. When the write window closes, Oracle Secure Backup does not allow further updates to the volume set until it expires or is relabeled, reused, unlabeled, or overwritten.
Attributes in a media family are applied to a volume in the media family at volume creation time.
When you create a media family, you specify a volume expiration policy that determines when volumes in a media family are expired, that is, eligible to be overwritten and recycled.
You can make RMAN backups, but not file system backups, to volumes that use a content-managed expiration policy. When you install Oracle Secure Backup, the software includes a default content-managed media family named RMAN-DEFAULT. As shown in Figure 2-12, you can delete backup pieces through the RMAN or Oracle Secure Backup interfaces. Volumes in a time-managed media family expire when they reach their volume expiration time. This is the time at which Oracle Secure Backup wrote backup image file number 1 to the first volume in the volume set.

This is the user-specified period of time during which volumes in a media family can be written to. This is the user-specified period of time in which volumes in a media family are not eligible to be overwritten. If you make RMAN backups to time-managed volumes, then it is possible for a volume to expire and be recycled while the RMAN repository reports the backup pieces as available. When you create a media family, you specify how to generate volume IDs that become part of the volume label. When Oracle Secure Backup labels a new tape volume, it assigns it a volume ID based upon the contents of a volume sequence file. Oracle Secure Backup constructs each volume ID by starting with the media family name, appending a dash, then appending a 6-digit sequence number, the first of which is 000001.
When you specify a volume sequence file, Oracle Secure Backup uses the named file for obtaining volume IDs. If you do not include any digits in the sequence number you create, then Oracle Secure Backup appends a 1 to the sequence number and increments that number by 1 each time the sequence number is used. You can also use the --vid option on the restore command to ensure that the volume being read is the correct one.
Oracle Secure Backup daemons are background processes that perform Oracle Secure Backup operations. An Oracle Secure Backup administrative domain uses a variety of daemons to perform backup, restore, and configuration tasks.
This section describes the Oracle Secure Backup daemons and indicates the hosts on the domain on which they run.
On the administrative server, observiced runs jobs at the request of the schedule daemon, cleans up log files and transcripts, and provides access to Oracle Secure Backup configuration data to other hosts in the domain.

In a cumulative incremental backup, Oracle Secure Backup backs up only those files that have changed since the last backup at a lower (numerical) backup level.
This technique is useful when you want to create an archive for offsite storage without disturbing your schedule of incremental backups. Dataset files employ a lightweight language that gives you the flexibility to build and organize the definitions of the data to be backed up. As shown in Figure 2-2, you can view this structure from the perspective of the operating system or the Oracle Secure Backup catalog.
As shown on the left part of Figure 2-2, the NEW_CLIENTS directory is automatically created during installation. You can create your own dataset directories and files and organize them into a tree-like structure. For example, you may instruct Oracle Secure Backup to back up the Oracle home on client host brhost2. A backup window is a time range within which Oracle Secure Backup performs scheduled backup jobs. If the backup window is closed, or if no backup window is defined, then scheduled backups will not run, although you can still run on-demand backups. For an example of how backup windows affect scheduled backups, assume that your only backup window opens daily from midnight to 2 a.m. On Windows systems, a privileged backup runs under the same account identity as the Oracle Secure Backup service on the Windows client.
Some types of backups are restartable from a mid-point, however, after such a failure occurs.
Some information for each checkpoint resides on the Oracle Secure Backup administrative server, whereas the remainder resides on the client host. If so, it periodically establishes a checkpoint that it can later use to restart the backup. Upon finding a restartable job, the scheduler restarts it and uses the same volume and drive in the same library in use when the interruption occurred.
You can use obtool or the Web tool to browse the catalog to determine what you have backed up.
The recovery catalog is stored in an Oracle database and is maintained independently by RMAN. The class of which your Oracle Secure Backup user is a member defines your right to browse the catalog. At the root of the file system appears a fictitious directory, called the super-directory, that contains all files and directories saved from the top-most file system level. The name of an object backed up yesterday as a directory may, in today's backup, refer to a file, and in tomorrow's backup, a symbolic link. The data selector describes, either explicitly or by inference, the identity of each backup image section containing the data of interest. Within a backup catalog, Oracle Secure Backup identifies each backup image section with a numerical backup ID.
Oracle Secure Backup consults the view mode each time it searches or displays a catalog directory. Oracle Secure Backup supplies an SBT interface that RMAN can use to back up database files to tape. For example, the storage selector identifies a database by name or DBID (unique numerical identifier), the host on which it resides, and the media family to use when backing it up.
Using this information, Oracle Secure Backup determines the corresponding database backup storage selector. You can use the Oracle Secure Backup SBT interface in conjunction with RMAN to restore database files to tape. A request is a locally-stored specification of a backup or restore operation that is not yet eligible to run. You should familiarize yourself with these settings because they determine the frequency with which the scheduler dispatches jobs. To learn about database backup and restore jobs, see "How RMAN Accesses Oracle Secure Backup". Oracle Secure Backup assigns each job a name that is unique among all jobs in the administrative domain. Oracle Secure Backup assigns each backup job an identifier whose prefix is the parent (dataset) job id, followed by a dot (.), then followed by a unique small number. The scheduler dispatches higher priority jobs over lower priority ones, providing all resources required to run the job are available. This log describes high level events such as the creation, dispatch, and completion times of the job. You can configure devices during installation or add a new device to an existing administrative domain.
It has a beginning and an end, which means that to access data in the middle of the tape, a device must read through the beginning part of the tape until it locates the desired data.
In this mode, Oracle Secure Backup sends commands to the robotic arm of the library to mount tapes for backup and restore operations. If a cleaning is required, then Oracle Secure Backup loads a cleaning cartridge, waits for the cleaning cycle to complete, replaces the cleaning cartridge in its original storage element, and continues with the requested load or unload.
Typically, an MTE is a robot arm that moves tape cartridges from library slots to tape drives. Typically, an IEE is a door-like mechanism that operators use to transfer tapes into and out of the library. Similarly, you can use the extractvol command to indicate that you are removing a volume manually from the library.
For example, you can instruct the library to load the tape in slot 3 into the drive named tape1.
You can use the importvol command to move volumes to internal slots in the library and the exportvol command to move volumes out of the tape library.
Because Oracle Secure Backup manages tape drive operations, it must be able to identify the drive as well as determine whether the drive is housed in a library.
To be usable by Oracle Secure Backup, each device must have at least one attachment, which describes a data path between a host and the device itself. SAN-attached devices are also distinguished by a World Wide Name (WWN), an internal identifier that uniquely names the device on the SAN. As shown in Figure 2-7, a backup section is the part of a backup image that fits on a single volume.
For example, volumes in a media family share a common naming pattern and policies used to write and keep data. As shown in Figure 2-9, a backup image is a file that consists of one or more backup sections. Similarly, backup sections are uniquely identified in the catalog by their backup section IDs. A volume tag is an alphanumeric string, up to 31 characters in length, that is typically obtained from a UPC barcode label affixed to the tape cartridge. The volume label serves a dual role, being both the label for the volume and the label of the first backup image on the volume.
Oracle Secure Backup numbers each backup image on a labeled volume set with a backup image file number, starting from 1.
After the last image, Oracle Secure Backup writes a tape file mark, then an end-of data (EOD) label, and then two more tape file marks. The EOD label contains a copy of the data in the preceding backup image label, except that the image file number is incremented by one. A volume set is a set of one or more tape volumes in which the first volume is continued onto the second, the second is continued onto the third, and so on.
For example, if the media family is full_backup, then a volume ID might be full_backup-000029. When a volume set is expired, Oracle Secure Backup automatically considers each volume in the set eligible to be overwritten and recycled. Every backup tries to append to the most recent volume in the media family; if this volume is full, then it writes to a new one.
The write window is a user-specified period of time that applies to all volumes in the set.
Note that if a backup is writing to a tape when the write window closes, the backup completes but no further backups are written to the volume.
As shown in Figure 2-12, volumes in a media family use either a content-managed expiration policy or time-managed expiration policy. You cannot delete or rename this media family, although you can modify certain attributes through the Web tool or the chmf command in obtool.

Deleting backup pieces by means of Oracle Secure Backup tools leaves the metadata in the RMAN repository inconsistent with the contents of your tapes.
Upon reaching this point in time, Oracle Secure Backup automatically considers each volume in the volume set eligible to be overwritten.
This setting prevents you from overwriting any volume in this media family until the specified amount of time has passed. You set the retention period to 14 days, which means that the data on all volumes in the volume set is retained for 14 days from the close of the write window.
Thus, volumes with a time-managed expiration policy can contain a mixture of file system backups and RMAN backup pieces. This file resides on the administrative server; its location is defined by the media family of the volume.
For example, you can create your own volume ID if you previously created a tape that is partially unreadable. Some daemons run continually, whereas others run only to perform specific work and then exit when they have finished. As explained in "Host Access Modes", these daemons run only in hosts using primary access mode; NDMP-accessed hosts do not have Oracle Secure Backup installed. The service daemon runs continually on the administrative server, media server, and client. Exchange, Sharepoint, and SQL Server) support a good portion of mission critical business operations.

For example, you can use Oracle Secure Backup to back up the root directory on a host or an Oracle Database home.
For example, a level 3 cumulative backup copies only that data that has changed since the most recent backup that is level 2 or lower. Oracle Secure Backup does not support the level 10 backup in conjunction with some platforms, including NAS devices such as Network Appliance filers. Oracle Secure Backup uses this directory as a starting point from which you can access every top-level file system object stored in the catalog. Table 2-2 shows the files that are backed up as well as the volume and image file to which they are written. Table 2-3 describes the effect of various data selectors on the file system object references. You control the view mode setting from the Oracle Secure Backup Web tool or command-line interface.
In other words, each file and directory restored from a full or an incremental backup is added to its destination directory.
An SBT backup initiated by RMAN is distinct from a file system backup, which is a scheduled or on-demand backup of any files on the file system (not just database files) initiated by Oracle Secure Backup.
Storage selectors act as a layer between RMAN, which backs up and restore the database, and the Oracle Secure Backup software, which manages the underlying media. This storage selector informs Oracle Secure Backup what devices, if any, to restrict this backup to and which media family (if any) to use. As explained in "Database Backup Storage Selectors", Oracle Secure Backup uses information encapsulated in storage selectors to interact with RMAN when performing restore operations.
A job is a request that has been forwarded to the Oracle Secure Backup scheduler and is eligible to be run.
When the user terminates the session, requests that are not yet sent to the scheduler are lost. For each trigger that fires that day, Oracle Secure Backup creates one new job for each dataset listed in the schedule. For example, if twenty jobs are in the scheduler and ready for execution, then Oracle Secure Backup executes the job with the lowest numeric schedule priority.
Oracle Secure Backup creates this transcript when dispatching the job for the first time and updates it as the job progresses. When configuring devices, the basic task is to inform Oracle Secure Backup about the existence of a device and then specify which media server can communicate with this device. Most magnetic tape systems use small reels that are fixed inside a cartridge to protect the tape and make handling of the tape easier. When a new volume is needed, Oracle Secure Backup scans the volumes in the library until it finds a suitable volume.
After the door is closed, the robotic arm transfers cartridges to internal slots in the library.
Data transfer elements are referenced only in the inventory display and indirectly by the drive (if any) that you select for an operation. When there is only one element of a type, the number can be omitted: iee1 and iee both refer to the first and only import export element. You can also use the unloadvol command to instruct the tape library to unload a volume from a tape drive to a particular storage element. Oracle Secure Backup must further determine which storage elements are available for storing tapes while not in use by the drive. Typically, an attachment includes the identity of a host plus a UNIX device special file name, a Windows device name, or NAS device name.
Systems such as Network Appliance filers permit access to SAN-attached devices through their WWN; for such systems, Oracle Secure Backup includes a reference to the WWN in the device attachment's raw device name.
Oracle Secure Backup obtains the volume ID in one of ways described in "Volumes in a Media Family". Many libraries are equipped with barcode readers, which enables Oracle Secure Backup to determine the identity of a tape without having to load it and read the volume label.
Similarly, a backup image label contains information about the following backup image and a copy of the volume information from the volume label. Oracle Secure Backup uses the EOD label to provide a volume ID, backup image file number, and sequence number for the next backup image without rewinding the volume.After you read a backup image, the volume is positioned after the tape file mark following the backup image that you just read and before the volume label of the next backup image. If the volume set is content-managed, then an individual volume of the set can expire before the remainder of the set. Oracle Secure Backup continues to append backups to the volume set until the end of this period. After data is first written to the volume, you cannot change the volume attributes other than by rewriting the volume. Note that a volume in a content-managed volume set can expire even though the other volumes in the set are not yet expired. If RMAN backups are deleted from tape at the Oracle Secure Backup level, or if RMAN backups on tape are unavailable or lost for other reasons, then you should immediately use the RMAN CROSSCHECK command to update the RMAN repository. If one volume becomes full, and if Oracle Secure Backup continues the backup onto subsequent volumes, then it assigns each volume the same retention period. Assume that Oracle Secure Backup first wrote to the first volume in the set on January 1 at noon and subsequently wrote data on 20 more volumes in the set. You can perform the backup again and use the --vidunique option, specifying a volume ID that keeps your volume IDs in sequence.
These Microsoft applications have traditionally been hosted on siloed, underutilized IT infrastructure and operational processes that were built based on the requirements of individual applications and processes.

When you have a performance issue or a database problem that is impacting your users, it is even more important to have experience on your side.
HIPL builds IT Infrastructures that achieve MAA standards and objectives by using Oracle MAA components and Industry best practices. Our best practices implementation of Oracle Grid Control for proactive monitoring paired with Oracle Data Guard for Disaster Recovery allows you to further reduce the risk of data loss and database downtime. HIPL has immense experience in GoldenGate architecture design, tuning, implementation, and management. HIPL’s performance optimization services contemplate all layers of technology that contribute to an optimal database platform.
Migration of an application can take on numerous different forms; from porting to a new database, to a re-write in a different development tool. For example, backup ID 25 can represent the Monday backup of the root directory on a host, whereas backup ID 6 represents the Tuesday backup. When a job requires operator assistance, Oracle Secure Backup prompts for assistance using the transcript. If sufficient eligible tapes are contained in the library storage elements, then no operator intervention is required to load the volumes needed to store the complete backup image. Because the library itself is not opened during this procedure, a re-inventory is not required. Oracle Secure Backup remembers the relationship between a volume tag and the backup images it contains in the catalog.
Thus, Oracle Secure Backup can obtain volume information without having to rewind the tape to read the volume label. For example, you could create media families specifically for onsite backups, offsite backups, and incremental backups.
If you change the media family attributes, then these changes do not apply to any volumes that have already been created in this family. The end result is increased total cost of ownership and inability to help business be more agile, introduce new services, and achieve operational efficiency. This is where HIPL’s enormous experience has succeeded in problem-solving and bringing our clients through a tough database issue.
