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 cycle. The same tape rotation enables you to get by with the minimum number of cartridges and not to be buried in used tapes.
Acronis Backup & Recovery 10 enables you to achieve full automation of tape rotation while backing up onto tape libraries.
This section provides you with useful information to choose a backup scheme and tape options for tape rotation.
To calculate the number of tapes required for tape rotation schemes, you can use the method described in the Tape planning section.
