Delete snapshot

Deleted snapshot data can't be recovered. Make sure to review carefully before deleting.

• When deleting HDD/SSD and CB1/FB1-based snapshots
  • To delete a full snapshot used as the base snapshot of an incremental snapshot, you must delete all related incremental snapshots beforehand.
  • For incremental snapshots, you can start deleting from the snapshot that was created last.
    • If you have 7 incremental snapshots and want to delete the 5th incremental snapshot, you need to select and delete the 7th, 6th, and 5th incremental snapshots.
• When deleting CB2/FB2-based snapshots
  • You can delete regardless of the snapshot creation order. (The first, middle, or last snapshot in the chain can be deleted)
  • Deleting a snapshot may change the actual size of other snapshots from the same original storage, and the snapshot billing capacity may also change.
  • For more information on the billing of each case of deleting CB2/FB2 snapshots, see the Billing impact for each case of CB2/FB2 snapshot deletion.

• The first snapshot in a snapshot chain is billed based on total capacity (virtual), while all subsequent snapshots are billed according to their used capacity (actual).
• When a snapshot is deleted, both the target snapshot and its child snapshots are affected.
• Since the used capacity (actual) is the metadata for changes, deleting a middle snapshot in the snapshot chain may modify the actual capacity of the child snapshots.
