Additional Backup Set Options | The options in this section are specific to the type of backup set: |
Backup set options | |
Use buffer | If checked, files will be copied to the DS-Client Buffer (i.e. as fast as possible for the given server and LAN speed). This will free up the backup source as fast as possible. Then the DS-Client will send the files from the DS-Client buffer to the DS-System. Note: This option cannot be used if Continuous Data Protection (CDP) is selected. This option is not applicable for VMware VADP backup sets. |
Detailed log | Records all files that are backed up (you can view them in the Activity Log). |
Stop on errors | DS-Client will stop a backup process or a VM replication process when the number of errors encountered reaches this specified value. • range 0-9999; the value 0 means that the number of errors encountered will not cause DS-Client to stop a backup process or VM replication process. • Note: The global default that appears in the New Backup Set Wizard or New Replication Set Wizard can be configured using the Windows DS-Client “MaxErrors” Advanced Parameter. |
Continuous Data Protection | Select this box to enable continuous data protection (CDP) in this backup set. To modify CDP settings for the backup set, click >>. Note: This option is unavailable when the Use buffer option is selected. |
Initial Backup | When creating a new backup set, select this check box to use the Initial Backup feature for the first backup. Click >> to select the Initial Backup Path. |
Initial replication | When creating a new VM replication set, select this check box to perform offline VM replication. Click >> to select a local disk location to which DS-Client should save the VM replication data. |
Disable Common Files | This box appears if the feature is activated by your service provider. If checked, the backup set’s files will be excluded from Common File storage reduction. This means duplicate files will be encrypted and backed up individually, thereby potentially increasing the stored size. • You can only set this feature in the New Backup Set Wizard. It cannot be changed afterwards. |
BLM (Infinite Generations) (Backup Lifecycle Management module must be enabled) | Backup sets are configured to save a specific number of generations. Once a backup item reaches this number of generations, the oldest will be overwritten with each new generation backed up. Select to configure this backup set for BLM. When applicable, the DS-Client will instruct DS-System to send a copy of the oldest generation (that is about to be overwritten) to the BLM Archiver. |
Use Local Storage • These options appear if you have the Local Storage Tool Enabled from your service provider, and you have specified a Local Storage Path in the "DS-Client Configuration Parameters Tab". | |
Save | Select this box to indicate this backup set will also be saved to a Local Storage location (at the DS-Client site). • Backup data will be sent to the location specified in the Local Storage Path box. |
Cache | Select this box to indicate this backup set will use the Local Storage as a cache, in case a backup session loses connection with DS-System. • Cached backup data will be sent to DS-System at the next connection opportunity (after synchronization). • Backup data will be sent to the location specified in the Local Storage Path box. |
Local Storage Path | Click [>>] to choose a specific local storage path for this backup set. • Opens the "Enter Local Storage Path". • If you do not make a selection, the path from the "DS-Client Configuration Parameters Tab" is used. |
Instant Recovery | Indicates if this backup set is being saved to an instant recovery vault. |
PreScan | If checked, the backup set is flagged to scan all files in the backup set prior to backup to display an estimated completion time for the backup. |
Compression Type | You can select the compression type: • LZOP: A faster compression than ZLIB, that comes at the expense of less compression. • ZLIB: This compression method will normally produce better compression than LZOP, but will take more time to compress. Four different ZLIB strengths are available (Global, High, Medium, and Low). “ZLIB Global” is the default value set in the DS-Client Advanced Configurations ‘DefaultCompression’ parameter; “ZLIB High” corresponds to a value of 9; “ZLIB Medium” = 6; and “ZLIB Low” = 3. • None: Disables compression for this backup set. (This will only apply to backups performed after this section is made. Any backups currently online will retain the compression type used at the time of backup.) |
Open Files (File system backup sets) • This information instructs the DS-Client about how to deal with Open (i.e. locked) files. (If the open file has been locked with Deny write by another process, the backup for this file will fail.) | |
Try Deny Write | Attempt to open backup file in 'Deny Write' mode. If this fails (because the file is already open), place the backup file in 'Allow Write' mode. |
Deny Write | This mode prevents any other process from writing to the backup file, while the DS-Client has it open. DS-Client will not back up the file, if another process has already opened it for write. (However, you can instruct the DS-Client to retry backing up the open file.) |
Prevent Write | Attempt to open backup file in 'Deny Write' mode. If this fails (because the file is already open), then open in Allow Write mode and lock the file, thereby preventing any process from writing to the file. This ensures that the most recent version of the file is backed up. |
Allow Write | Allow another process to read/write to the backup file (no restrictions). Since other applications can write to the file while it is being backed up, this can affect file consistency. |
Retry times | Specifies the number of times you want the DS-Client to attempt to backup the file. (Max. 10 retries). |
Retry intervals | Specifies the interval between retries. (Maximum of 999 seconds). |
Pre/Post | Click Pre/Post to access the Pre & Post Execution dialog box. For more information, see "Pre & Post Execution". |
Exclude old files (File system backup sets) | Click to access the Exclude Old Files dialog box. For more information, see "Exclude Old Files". • Note: This option is not available if the Windows “System State” or “Services Database” is selected for backup. |
Additional Backup Set Options | MySQL backup sets. |
Add locks around insert statements | Lock tables before inserting data on restore. (See the MySQL manual page for ‘mysqldump’ for more information.) |
Add MySQL specific table create options | Add MySQL specific extensions to the backed up database dump. (See the MySQL manual page for ‘mysqldump’ for more information.) |
Insert statement type | Specify how table rows are inserted into the database dump (i.e. the style of the ‘INSERT’ statement). (See the MySQL manual page for ‘mysqldump’ for more information.) • Extended - Fast insert. Might not be useful for manual loading into non-MySQL databases. • Complete - Uses complete ‘INSERT’ statements that include column names when inserting rows. • Normal - Standard insert. Slower, but can be more portable to other databases. |
Table dumping option | Specify how tables are dumped. (See the MySQL manual page for ‘mysqldump’ for more information.) • Lock all tables - Prevent changes to data while backup is in progress (sets the tables to read-only mode for duration of backup). [This option is like using the --lock-tables dump option from the command line.] • Single transaction - [only works with transactional tables] This dump approach also prevents changes to the backup data, but does not set tables to read-only mode. • Do not lock tables - If selected, the tables can be changed during the creation of the dump file. Note the consistency impact this can have on the backup. [This option is like using the --skip-lock-tables dump option from the command line.] • None - Dump will be performed using the ‘mysqldump’ function with no special conditions. |
Additional Backup Set Options | Email message backup set for Microsoft Exchange Server using MAPI |
E-Mail Scan Policy • This section appears only for Microsoft Exchange Server email message backup sets (DS-MLR) that use MAPI. Note: Functionality for discontinued backup sets might still work, even though they are no longer officially supported. | |
Full scan: Always | [Default] This is the default behavior for Email message backup sets for Microsoft Exchange Server using MAPI. • Each backup of the target performs a full scan of all items in the target folder. |
Full scan: Plus Incremental | Performs a full scan of the target folder on first backup, followed by incremental backups. • During incremental backups, DS-Client / DS-MLR will only retrieve the new or modified items from each folder. • Speed is the benefit of this option. However, since it does not detect items that have been removed from a folder, periodic full backups that perform a full scan should be performed. |
E-Mail Scan Policy Schedule Over-ride Rules [OPTIONAL] • This entire section is optional. It provides more precise control over the full scan. • These over-ride rules are applied in addition to the regular backup schedule for this backup set. This means the backup set must be scheduled to run on the first day of the month, if the over-ride rule “Full every month on 1st day...” will apply. | |
Do not start full scan on | Prevents a full scan from being performed during the time window on the selected day(s). • This skips performing a full scan of the backup set’s target folders, for up to the maximum number of consecutive times specified in the ‘MaxNonFullDumps’ parameter of the DS-Client Advanced Parameters (Setup Menu > Configuration > Advanced Tab). |
Full every | Forces a backup with a full scan to be performed at the specified interval. • hour(s), day(s), week(s), month(s), or year(s) |
Full every week on | Forces a full scan to be performed on a specific day of the week. • You must specify a time, after which the backup with a full scan can be performed. |
Full every month on | Forces a full scan to be performed on a specific day of the month. • You must specify a time, after which the backup with a full scan can be performed. |
Additional Backup Set Options | Local DS-VDR & VMware VADP backup sets. |
Backup Virtual Machine’s snapshots (Local DS-VDR) | • ON: Backup will ‘export’ the actual running virtual machine and all its snapshots. • OFF: Backup will ‘export’ the actual running virtual machine only (no snapshots). |
Export to host (Local DS-VDR) | This list contains the available ESXi hosts where you can export the selected virtual machines. You must assign one as the target. • Click [>>] to open the “Specify Credentials” dialog box. |
Export to datastore (Local DS-VDR) | This is a list of available Datastores on the destination host where you can export the individual virtual machine disk. • You must assign one as the target. |
Use FLR | Configures the VMware VADP backup set to be able to perform File Level Restore (FLR). |
Snapshot all VMs in the backup set at the same time | If selected: • If there are multiple virtual machines in the same backup set, DS-Client will perform snapshots of all the virtual machines at the same time. If not selected: • If there are multiple virtual machines in the same backup set, DS-Client will perform sequential snapshots of each virtual machine, waiting until the previous snapshot completes before starting with the next snapshot. |
Attempt to quiesce I/O before taking snapshot | Pause the applications to guarantee a consistent and usable backup. • This option requires that the VMware tools are properly installed and configured on the guest operating system of the virtual machine for application consistent backups. |
Attempt to use CBT for backing up Virtual Machines | When this option is selected, DS-Client will attempt to reconfigure virtual machines to use Changed Block Tracking (CBT). CBT monitors whether the disks have been changed between backup sessions and, when a disk has not been changed, improves backup performance. |
Use Local DS-VDR | Select this option to use the Local DS-VDR Tool. For more information and applicable requirements, see “VMware VADP backup sets (Windows or Linux)”. • Note: This option is only available in the New Backup Set Wizard and cannot be changed after the backup set has been created. |
Backup Virtual Machine memory | • ON: Saves the virtual machine state (running programs loaded in memory). • OFF: Backs up the virtual machine as if it were not running. |
Verify disks signature interval (generations) (Not applicable to Local DS-VDR) | If this option is selected, a VMware VADP backup set that has Changed Block Tracking (CBT) enabled will validate the disk signature of a protected virtual machine after a specified number of backups. The interval count starts from the first backup after the setting is enabled. If a disk signature mismatch is detected, a master generation is sent to the DS-System for the affected virtual disk (vmdk). Valid values are as follows: • 0 = Disables the disk signature validation process. • 1 = Validates the disk signature after every backup. • 2 to 100 = Validates the disk signature after the specified number of backups. The default is 10. Note: Running this verification process will consume more resources and result in the backup process taking longer to complete, especially if it fails the signature verification and a new master is enforced. |
Additional Backup Set Options | Physical to Virtual backup sets. (whose destination is to a VMware VADP vCenter Server) |
Export to vCenter Server | Enter the IP address of the vCenter Server where you want to ‘virtualize’ the selected physical computer. You must supply the credentials to the vCenter Server for a user with sufficient permissions to create a virtual machine. • Click [>>] to open the “Specify Credentials” dialog box. • Note: You cannot use Chinese characters for these credentials (username and password) because the VMware vCenter Converter does not support them. |
Export to datacenter | Once DS-Client / Local DS-VDR Tool connects to the vCenter Server, this list displays the available datacenters. • You can select a different one (if more than one are available). |
Export to host | Once you select the datacenter, you will be able to select a specific host’s IP address where the ‘virtualized’ machine will be created. You must supply the credentials to this host. • Click [>>] to open the “Specify Credentials” dialog box. |
Export to datastore | After selecting the destination host, you must select one of the defined vCenter Server datastores to which the new virtual machine will belong. |
Physical machine’s OS | You must specify the operating system of the target physical machine for DS-Client to handle the conversion properly. • Windows • Linux |
Helper VM’s IP | [This box appears for target physical machines running on Linux.] When you convert a powered-on Linux machine, VMware Converter Standalone creates a ‘Helper Virtual Machine’ on the destination. This ‘Helper VM’ needs network access to the source machine to clone the source files. • You must have your network administrator assign a dedicated IP address for this backup set. If you create another Physical-to-Virtual backup set, you must obtain another, unique, dedicated IP address. |
Helper VM’s Netmask | [This box appears for target physical machines running on Linux.] • Ask your network administrator what should be used. Typically, this is “255.255.255.0”. |
Helper VM’s Gateway | [This box appears for target physical machines running on Linux.] • Ask your network administrator what address should be used. Typically, this will be some unique IP address on the same subnet as the “Helper VM’s IP”. • The gateway address is the IP address that the local host uses to forward IP datagrams to other IP networks. This is either the IP address of a local network adapter or the IP address of an IP router (such as a default gateway router). |
Perform incremental conversions after the first session. | This option configures how a converted virtual machine is handled on the destination vCenter Server. • OFF: (Default) Each conversion creates a new virtual machine in the vCenter Server. (Note the space considerations, since you must perform manual deletes from the vCenter Server.) • ON: Each subsequent conversion goes to the same virtual machine. |
