Tape Rotation - ACRONIS BACKUP AND RECOVERY 10 ADVANCED SERVER SBS EDITION - UPDATE 3 User Manual

If you leave this option unchanged, then the backups, belonging to the policy or plan being created,
might be written onto tapes containing backups written by different backup policies and comprising
of data from different machines. Similarly, backups from other policies might be written onto the
tapes containing this policy's backups. You will not have a problem with such tapes, as the program
manages all the tapes automatically.
When this option is enabled, the backups, belonging to the policy or plan being created, will be
located on a separate tape set. Other backups will not be written to this tape set.
If the console is connected to the management server
The Use a separate tape set option has more precise definitions. So for the backup policy to be
created you can use a separate tape set for all machines or for each single machine.
The A single tape set for all machines option is selected by default. Generally this option ensures
more efficient usage of tapes, than the A separate tape set for each single machine option.
However the second one can be useful, for example, when there are special requirements to
store the tapes with backups from a specific machine off-site.
When the Use a separate tape set option is enabled, there might be a case when the backup has to
be written onto a tape that is currently out of the tape library device. Define what to do in this case.

Ask for user interaction - the backup task will enter the Need Interaction state and wait for the
tape, with the required label, to be loaded into the tape library device.
 Use a free tape - the backup will be written onto a free tape, so the operation will be paused
only if there is no free tape in the library.
Always use a free tape
If you leave the options below unchanged, then each backup will be written onto the tape specified
by the Use a separate tape set option. With some of the options below enabled, the program will
add new tapes to the tape set every time when a full, incremental or differential backup is created.

For each full backup
The preset is: Disabled.
When this option is enabled, each full backup will be written onto a free tape. The tape will be
loaded to a drive especially for this operation. If the Use a separate tape set option is enabled, only
incremental and differential backups of the same data will be appended to the tape.

For each differential backup
The preset is: Disabled.
When this option is enabled, each differential backup will be written onto a free tape. This option is
available only when using free tape for each full backup is selected.
 For each incremental backup
The preset is: Disabled.
When this option is enabled, each incremental backup will be written onto a free tape. This option is
available only when using free tape for each full and differential backup is selected.

Tape rotation

If all backups are deleted from a tape, i.e. if information about the last backup on the tape is deleted
from the storage node database, the tape is considered as empty and can be reused during a backup
