Snapshot sequence and access time
After a mirror snapshot backup, the access time of the files in the snapshot is reset to the access time of the original (primary) disk data. The access time of the snapshot data continues to match that of the data on the primary until the mirror is resynchronized with the primary. This behavior is normal for Snapshot Manager and applies to primary client backups as well as to off-host backups.
The figure shows the following phases:
Phase | Snapshot sequence and access time description |
|---|---|
Phase 1 | Last file access on primary: 08/29/05 at 8:01 pm |
Phase 2 | Mirror was synchronized with primary and split at 8:24 pm. |
Phase 3 | Snapshot taken on mirror at 8:24 pm. |
Phase 4 | Backup of mirror was completed at 10:14 pm; file access time on mirror is reset to 8:01 pm. |
