Limitations 
Limitations of tape library usage are the following: 
1.  The consolidation (p. 343) 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. 343) 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. 44) section. 
5.  Barcode printers are not used.

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. 
If a tape was used previously, the RSM tries to detect the registered application the tape is concerned 
to. If the application is not found, the RSM will move the tape into the Unrecognized  pool. If the 
application is not found, but the RSM database has no information about the tape, it will be moved 
into the Import pool. If the RSM database has the information, the tape moves into its own pool of 
the application. 
Acronis Backup & Recovery 10 Storage Node provides the RSM to detect the tapes written by Acronis 
True Image Echo, Acronis True Image 9.1 product families and by components of Acronis Backup &
