Apart from the regular backup methods using TSM BA Client and TDP Client backups, there are few other backup types available. From your local workstation, you can back up one or more volumes as a single object, image backup, on your system. A snapshot image backup performs an online image backup of a volume while the volume remains active and available for read and write operations. To use this feature put the snapshotproviderfs option in the dsm.opt file to enable snapshot-based file backup and archive operations, and also to specify a snapshot provider.
Conservation of resources on the server during backups because only one entry is required for the image. For Linux86 and Linux IA64, by default, Tivoli Storage Manager performs a snapshot image backup of file systems that are on a logical volume that the Linux Logical Volume Manager creates. The snapshotproviderimage option enables snapshot-based image backup, It also specifies a snapshot provider for AIX 5.3 and greater JFS2 and LINUX_LVM file systems. You can perform incremental-by-date of last image backup, regardless of whether the full image is backed up, by using offline or online image backup. Does not mark files inactive on the server for files that are deleted from your client machine.
The traditional static image backup prevents write access to the volume by other system applications during the operation.
You use the dynamicimage option to back up the volume as is, without remounting it as read-only. Corruption of the backup can occur if applications write to the volume while the backup is in progress. Dynamic: Specifies that you want to perform an image backup if the volume cannot be unmounted and remounted as read-only. Static: Performs an image backup during which the volume is unmounted and remounted as read-only. Snapshot: Specifies that you want to perform a snapshot image backup during which the volume is available to other system applications. When backing up NAS files systems, the Tivoli Storage Manager server uses Network Data Management Protocol (NDMP) to connect to the NAS file server.
With this feature of Tivoli Storage Manager, you can back up to storage devices without moving the data over the LAN. An NDMP backup is usually an image backup because the NAS filer performs the backup as an entity without telling Tivoli Storage Manager about the content.
Additionally, Tivoli Storage Manager can create a table of contents (TOC) during backup and store the TOC afterwards in a dedicated storage pool.
Although an NDMP backup is usually started and controlled by a Tivoli Storage Manager server, a Tivoli Storage Manager web client can also initiate and control an NDMP backup or restore.

IBM's TSM backup product goes super-fast when backing up to the Elastic Storage parallel file system, according to company trials. Servers running TSM were linked to an Elastic Storage array in a proof-of-concept test by IBM engineers in Germany, who blogged about the results.
The IBM bloggers say the single GPFS GNR file system used by the TSM server comprised two GPFS pools whereby each pool was configured on virtual disk (vdisk) providing 3-way fault tolerance. This suggests that, in general, backing up to parallel file systems is going to be faster than backing up to single-access file systems. An on-demand identity management service enables that protects your data through centralized access control.

USA Cycling is the official governing body for all disciplines of competitive cycling in the United States. The white boxes are the data functions, the yellow ellipses are the control datasets, the blue boxes are the data stores, and the green boxes are the recovery logs and trace datasets. As a guide, a single track record using half track blocking, and getting 3:1 compression will use about 160KB on ML1. If a dataset continues to be unused, it will eventually be migrated off to ML2 (migration level 2), which is usually high capacity cartridge. Migrated datasets are given a special catalog entry, with a volser of MIGRAT, to indicate that the dataset is migrated.
Control Data Set) keeps a record of what has been migrated, and where the migrated data is held. Primary space management does all the space management functions on the primary, or ML0 disks. So if you are expecting HSM to delete data and this is not happening, one possibility is that HSM requires a backup before it will delete the data. Interval migration runs every hour, and checks each volume occupancy against the SMS threshold settings for the volume's storage pool. You can configure these backups according to your requirements and infrastructure availability. Use the snapshotproviderimage option to enable snapshot-based online image backup and also to specify a snapshot provider.
This is the default for file systems on a logical volume that the Linux Logical Volume Manager creates.
Tivoli Storage Manager uses NDMP to initiate, control, and monitor a file system backup or restore operation.

The storage devices must be under the direct control of the NAS file server, which means that they must be directly attached or connected through a supported SAN environment. The GNR system was comparable to an Elastic Storage Server model GL2, comprised of two GNR servers and 116 NL-SAS drives.
If you have these then your backup and archive, and subsequent restores, could move data around like a dragster roaring down a speed strip.
The site was founded in 2000 and provides hints and tips on how to manage your data, strategic advice and news items. If allowed by parameters, it will delete temporary and expired datasets, release unused space, then migrate data to ML1 or ML2 as appropriate, until all volumes are below their SMS thresholds.
If the management class criteria are met it moves data from ML1 to ML2, it runs TAPECOPY commands if they are needed and it deletes expired migrated datasets. Other things that can go wrong is that for SMS volumes the storage group containing the volumes must be defined with AM=Y and the HSM parameter 'Scratch expired Data Sets' must be set to YES.
If the high threshold is exceeded, then DFHSM will migrate eligible datasets until the low threshold is reached or no more data sets are eligible. If you are running in a sysplex with several LPARs, its best to run several concurrent backup tasks from a single LPAR, rather than spreading the tasks between LPARS. If a CDS fails, it can be recovered from backup, then the log updates applied to get it back to the point of failure.
O TSM dispoe de mecanismos, para consolidar automaticamente as informacoes remanescentes, na menor quantidade de midias possivel.
Providers include Volume Shadowcopy Service (VSS) and Logical Volume Snapshot Agent (LVSA). The LVSA is provided for customers that migrate from previous versions of Tivoli Storage Manager, where LVSA is used.
Each time a single file restore from an NAS image backup is done, Tivoli Storage Manager loads the TOC from the dedicated storage pool into a temporary database table.
You would typically enter this command once when setting up HSM, and then just enter it again if you wanted to change the parameters. Without the TOC, you can restore single files from a NAS backup image by providing exact information about the single file and the image it is in.
Small datasets could be archived to ML1, but still use the same space, so small datasets are held as records in Small Data Set Packing datasets (SDSPs). This is an issue if you do not use DFHSM to backup your data, so it is possible to apply a patch to HSM that allows it to delete data that it has not backed up.
