level (p. 112) option is set to None). Use the sector-by-sector backup for backing up drives with
unrecognized or unsupported file systems and other proprietary data formats.
4.7.22 Tape management
These options are effective when the backup destination is a tape device.
Use a separate tape set for each single machine
The preset is: Disabled.
Tapes within one pool can be grouped into so-called tape sets.
If you leave this option disabled, data from different machines will be backed up on all tapes
belonging to a pool. If the option is enabled, backups of each machine will be stored on a separate
tape set.
The option applies to backing up to a storage node.
Enable file recovery from disk backups stored on tapes
The preset is: Disabled.
If this check box is selected, at each backup, the software creates supplementary files on a hard disk
of the machine where the tape device is attached. File recovery from disk backups is possible as long
as these supplementary files are intact. The files are deleted automatically when the tape storing the
respective backups is erased (p. 211), removed (p. 214) or overwritten.
The supplementary files' locations are as follows:
In Windows XP and Server 2003: %ALLUSERSPROFILE%\Application
Data\Acronis\BackupAndRecovery\TapeLocation.
In Windows Vista and later versions of
Windows: %PROGRAMDATA%\Acronis\BackupAndRecovery\TapeLocation.
In Linux: /var/lib/Acronis/BackupAndRecovery/TapeLocation.
The space occupied by these supplementary files depends on the number of files in the respective
backup. For a full backup of a disk containing approximately 20,000 files (the typical workstation disk
backup), the supplementary files occupy around 150 MB. A full backup of a server containing 250,000
files may produce around 700 MB of supplementary files. So if you are certain that you will not need
to recover individual files, you can leave the check box cleared to save the disk space.
When you configure a single-pass disk and application backup (p. 314), the Enable file recovery from
disk backups stored on tapes check box is automatically selected. You can clear it only if you change
the backup destination or disable single-pass backup.
If the supplementary files were not created during backup, or have been deleted, you still can create
them by rescanning (p. 211) the tapes where the backup is stored. This does not apply to backups
created by Acronis Backup & Recovery 11 Update 0 (build 17318) and earlier.
Eject tapes after successful backups
The preset is: Disabled.
When this check box is selected, the software will eject tapes after any successful backup. If,
according to the backup plan, other operations follow the backup (such as the backup validation or
replication to another location), the tape will be ejected after completion of these operations.
