Restore an archived Amazon EBS snapshot - Amazon EBS

Restore an archived Amazon EBS snapshot

Before you can use an archived snapshot, you must first restore it to the standard tier. The restored snapshot has the same snapshot ID, encryption status, IAM permissions, owner information, and resource tags that it had before it was archived. After it is restored, you can use it in the same way that you use any other snapshot in your account. The restored snapshot is always a full snapshot.

When you restore a snapshot, you can choose to restore it permanently or temporarily.

If you restore a snapshot permanently, the snapshot is moved from the archive tier to the standard tier permanently. The snapshot remains restored and ready for use until you manually re-archive it or you manually delete it. When you permanently restore a snapshot, the snapshot is removed from the archive tier.

If you restore a snapshot temporarily, the snapshot is copied from the archive tier to the standard tier for a restore period that you specify. The snapshot remains restored and ready for use for the restore period only. During the restore period, a copy of the snapshot remains in the archive tier. After the period expires, the snapshot is automatically removed from the standard tier. You can increase or decrease the restore period or change the restore type to permanent at any time during the restore period. For more information, see Modify the restore period for a temporarily restored Amazon EBS snapshot.

If you are restoring snapshots that are associated with a disabled AMI, and you intend to use that AMI, you must first permanently restore all of the associated snapshots and then re-enable a disabled AMI before you can use it. You can't enable an AMI if the associated snapshots are temporarily restored. You can use the following command to find all of the snapshots associated with an AMI.

aws ec2 describe-images --image-id ami_id \
  --query Images[*].BlockDeviceMappings[*].Ebs[].SnapshotId[]

You can restore an archived snapshot using one of the following methods.

Console
To restore a snapshot from the archive

Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.

  1. In the navigation pane, choose Snapshots.

  2. In the list of snapshots, select the archived snapshot to restore, and then choose Actions, Restore snapshot from archive.

  3. Specify the type of restore to perform. For Restore type, do one of the following:

    • To restore the snapshot permanently, select Permanent.

    • To restore the snapshot temporarily, select Temporary, and then for Temporary restore period, enter the number of days for which to restore the snapshot.

  4. To confirm, choose Restore snapshot.

AWS CLI
To permanently restore an archived snapshot

Use the restore-snapshot-tier AWS CLI command. For --snapshot-id, specify the ID of the snapshot to restore, and include the --permanent-restore option.

$ aws ec2 restore-snapshot-tier \
--snapshot-id snapshot_id \
--permanent-restore

For example, the following command permanently restores snapshot snap-01234567890abcedf.

$ aws ec2 restore-snapshot-tier \
--snapshot-id snap-01234567890abcedf \
--permanent-restore

The following is the command output.

{
    "SnapshotId": "snap-01234567890abcedf",
    "IsPermanentRestore": true
}
To temporarily restore an archived snapshot

Use the restore-snapshot-tier AWS CLI command. Omit the --permanent-restore option. For --snapshot-id, specify the ID of the snapshot to restore, and for --temporary-restore-days, specify the number of days for which to restore the snapshot.

--temporary-restore-days must be specified in days. The allowed range is 1 - 180. If you do not specify a value, it defaults to 1 day.

$ aws ec2 restore-snapshot-tier \
--snapshot-id snapshot_id \
--temporary-restore-days number_of_days

For example, the following command temporarily restores snapshot snap-01234567890abcedf for a restore period of 5 days.

$ aws ec2 restore-snapshot-tier \
--snapshot-id snap-01234567890abcedf \
--temporary-restore-days 5

The following is the command output.

{
    "SnapshotId": "snap-01234567890abcedf",
    "RestoreDuration": 5,
    "IsPermanentRestore": false
}
