Configure fast snapshot restore for an Amazon EBS snapshot

Fast snapshot restore is disabled for a snapshot by default. You can enable or disable fast snapshot restore for snapshots that you own and for snapshots that are shared with you. When you enable or disable fast snapshot restore for a snapshot, the changes apply to your account only.

Note

When you enable fast snapshot restore for a snapshot, your account is billed for each minute that fast snapshot restore is enabled in a particular Availability Zone. Charges are pro-rated and have a minimum of one hour.

When you delete a snapshot that you own, fast snapshot restore is automatically disabled for that snapshot in your account. If you enabled fast snapshot restore for a snapshot that is shared with you, and the snapshot owner deletes or unshares it, fast snapshot restore is automatically disabled for the shared snapshot in your account.

If you enabled fast snapshot restore for a snapshot that is shared with you, and it has been encrypted using a custom CMK, fast snapshot restore is not automatically disabled for the snapshot when the snapshot owner revokes your access to the custom CMK. You must manually disable fast snapshot restore for that snapshot.

After you enable fast snapshot restore for a snapshot, it enters the optimizing state. Snapshots that are in the optimizing state provide some performance benefits when using them to restore volumes. They start to provide the full performance benefits of fast snapshot restore only after they enter the enabled state.
