Answer

No, Snapshot retention works based on the snapmirror policy's 'Label' and 'Keep' function. Snapshots has no expiry-date set on them.

Additional Information

  • Below output shows an example "snapmirror policy" with daily label and keep count of 7.

::> snapmirror policy show
Vserver Policy             Policy Number         Transfer
Name    Name               Type   Of Rules Tries Priority Comment
------- ------------------ ------ -------- ----- -------- ----------
test_vserver CloudBackupDefault vault      1     8  normal  Vault policy with daily rule.
  SnapMirror Label: daily                              Keep:       7
                                                 Total Keep:       7

  • After accumulation of 7 daily snapshots, next "snapmirror update" which replicates a new 'daily' snapshot will replace the oldest 'daily' snapshot present on the volume/object-store.
