ZDB to tape | (ZDB specific term) A form of zero downtime backup where |
| data in the replica produced is streamed to a backup medium, |
| typically tape. Instant recovery is not possible from such a |
| backup, so the replica need not be retained on the disk array |
| after backup completion. The |
| using standard Data Protector restore from tape. On split mirror |
| arrays, split mirror restore can also be used. |
| See also zero downtime backup (ZDB), ZDB to disk, instant |
| recovery, ZDB to disk+tape, and replica. |
zero downtime | A backup approach in which data replication techniques, |
backup (ZDB) | provided by a disk array, are used to minimize the impact of |
| backup operations on an application system. A replica of the |
| data to be backed up is created first. All subsequent backup |
| operations are performed on the replicated data rather than the |
| original data, while the application system can be returned to |
| normal operation. |
