If all cartridges in a tape library have barcodes, the library is ready to be automatically managed by
software.
Tape libraries are a cost-effective solution for data storages with huge capacity. Moreover, tape is
perfect for archiving because cartridges can be stored off-site for enhanced data security. However
reading even a small amount of data from a tape library takes much more time (from several seconds
to several minutes) than from other types of data storages. The best practice of tape usage is "LESS
requests to write/read LARGER amount of data". So systematic access to very large quantities of data
is more suitable for a tape library than random access to small portions of data.
4.1.3.3. Limitations
Limitations of tape library usage are the following:
1. The consolidation (p. 392) operation is not possible for archives located on tapes. Deletion of a
single separate backup is impossible from a tape. It is possible to delete all the backups stored on
a tape. However, after this operation all the incremental and differential backups, stored on
other tapes and based on the deleted backups, cannot be used for data recovery. In a Custom
backup plan's retention rules the If deletion of a backup affects other backups > Consolidate the
backup option is disabled. Only the Postpone the deletion option is available.
2. Deduplication (p. 392) is not available for archives located on tape storage devices.
3. File recovery from a disk backup stored on tape is possible, but can take a very long time.
4. A tape with backups written by the storage node cannot be read on a tape device, locally
attached to a machine, the agent is installed on, because of a difference in tape format. To get
information about the readability of the archives on tapes, written by different components of
other versions of the product by means of Acronis Backup & Recovery 10, see the Tape
compatibility table (p. 54) section.
5. Barcode printers are not used.
4.1.3.4. RSM Media Pools
Acronis Backup & Recovery 10 uses Windows Removable Storage Manager (RSM) to manage tape
cartridges belonging to tape libraries.
To separate access to media by different programs the RSM uses so called Media Pools that are
logical media groups. There are two categories of media pools in the manager: System and
Application.
System media pools include Free pool, Import pool and Unrecognized pool. The System pools hold
media that are not currently used by applications. The Free pool holds media that are considered as
free and can be used by applications. The Import and Unrecognized pools are temporary pools for
media that are new in certain library.
Through RSM an application can get its own pools with proper names, move media from the Free
pool into its own pools, use its own pools’ media for correct purpose, return media to the Free pool,
etc.
Acronis Backup & Recovery 10 Storage Node manages the tapes belonging to the Acronis pool.
If you fill tape library slots with unused tapes, all the tapes will be included into the Free pool
automatically.
