Extend the retention period of a snapshot

Updated at: 2025-02-07 09:01

If you specify a custom retention period for snapshots that you created, you can extend the retention period before the snapshots expire.

Note

If the remaining snapshot retention period of a snapshot is a few days such as three days, Released After {days} Days appears in the Retention Period column corresponding to the snapshot on the Disk Snapshots tab.

Limits

  • You cannot extend the retention period of snapshots that are permanently retained.

  • You cannot extend the retention period of snapshots that are shared with you.

  • You can extend the retention period of existing snapshots but cannot shorten the retention period.

Considerations

  • Alibaba Cloud charges standard snapshot storage fees in each region based on the snapshot capacity and storage duration. Extending the retention period of snapshots increases snapshot storage costs. For more information, see Snapshots.

  • If the Delete Automatic Snapshots While Releasing Disk attribute is enabled for a disk, when the disk is manually released or released together with the associated instance, or when the operating system of the associated instance is replaced, the automatic snapshots of the disk are automatically deleted on the disk release even if the automatic snapshot retention period does not end. For more information, see Configure an automatic snapshot policy for a cloud disk.

Procedure

  1. Log on to the ECS console.

  2. In the left-side navigation pane, choose Storage & Snapshots > Snapshots.
