Limitations

The limitations of tape device usage are the following:

1. The consolidation of backups located on tapes is not possible. As a result, usage of backup schemes has certain peculiarities.
2. The deduplication of backups located on tapes is not possible.
3. Simplified naming of backup files is not possible for backups stored on tapes.
4. You cannot recover under an operating system from a backup stored on tapes if the recovery requires the operating system reboot. Use bootable media to perform such recovery.
5. Files cannot be recovered from disk-level backups created by Acronis Backup & Recovery 11 Update 0 (build 17318) and earlier.

   Files can be recovered from a disk-level backup created by Acronis Backup & Recovery 11 Update 0.5 (build 17437) only after you rescan the tapes where the backup is located.

   The Enable file recovery from disk backups stored on tapes option value determines whether files and folders can be recovered from disk-level backups created by Acronis Backup & Recovery 11.5.

6. You can validate any backup or archive stored on tapes, but you cannot select for validation an entire tape-based vault or tape device.
7. You cannot attach or detach a tape-based vault.
8. A managed tape-based vault cannot be protected with encryption. Encrypt your archives instead.
9. You cannot create a managed tape-based vault with the backward compatibility property. This means that Acronis Backup & Recovery 10 agents cannot back up to Acronis Backup & Recovery 11.5 managed tape-based vaults.
10. The software cannot simultaneously write one backup to multiple tapes or multiple backups through the same drive to the same tape.
11. Devices that use the Network Data Management Protocol (NDMP) are not supported.
12. Barcode printers are not supported.
