Archive a snapshot

You can archive any snapshot that is in the completed state and that you own in your account. You can't archive snapshots that are in the pending or error states, or snapshots that are shared with you. For more information, see Considerations and limitations.

If the snapshot is associated with one or more AMIs, then you must first disable those associated AMIs before you can archive the snapshot. For more information, see Disable an AMI.

Archived snapshots retain their snapshot ID, encryption status, AWS Identity and Access Management (IAM) permissions, owner information, and resource tags. However, fast snapshot restore and snapshot sharing are automatically disabled after the snapshot is archived.

You can continue to use the snapshot while the archive is in process. As soon as the snapshot tiering status reaches the archival-complete state, you can no longer use the snapshot.

You can archive a snapshot using one of the following methods.

Restore an archived 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 or restore type for a temporarily restored 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.


$ C:\> 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/.

In the navigation pane, choose Snapshots.
In the list of snapshots, select the archived snapshot to restore, and then choose Actions, Restore snapshot from archive.
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.
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
}

Modify the restore period or restore type for a temporarily restored snapshot

When you restore a snapshot temporarily, you must specify the number of days for which the snapshot is to remain restored in your account. After the restore period expires, the snapshot is automatically removed from the standard tier.

You can change the restore period for a temporarily restored snapshot at any time.

You can choose to either increase or decrease the restore period, or you can change the restore type from temporary to permanent.

If you change the restore period, the new restore period is effective from the current date. For example, if you specify a new restore period of 5 days, the snapshot will remain restored for five days from the current date.

Note

You can end a temporary restore early by setting the restore period to 1 day.

If you change the restore type from temporary to permanent, the snapshot copy is deleted from the archive tier, and the snapshot remains available in your account until you manually re-archive it or delete it.

You can modify the restore period for a snapshot using one of the following methods.

Console

To modify the restore period or restore type

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

In the navigation pane, choose Snapshots.
In the list of snapshots, select the snapshot that you previously temporarily restored, and then choose Actions, Restore snapshot from archive.
For Restore type, do one of the following:
- To change the restore type from temporary to permanent, select Permanent.
- To increase or decrease the restore period, keep Temporary, and then for Temporary restore period, enter the new restore period in days.
To confirm, choose Restore snapshot.

AWS CLI

To modify the restore period or change the restore type

Use the restore-snapshot-tier AWS CLI command. For --snapshot-id, specify the ID of the snapshot that you previously temporarily restored. To change the restore type from temporary to permanent, specify --permanent-restore and omit --temporary-restore-days. To increase or decrease the restore period, omit --permanent-restore and for --temporary-restore-days, specify the new restore period in days.

Example: Increase or decrease the restore period

The following command changes the restore period for snapshot snap-01234567890abcedf to 10 days.


$ aws ec2 restore-snapshot-tier \
--snapshot-id snap-01234567890abcedf 
--temporary-restore-days 10

The following is the command output.


{
    "SnapshotId": "snap-01234567890abcedf",
    "RestoreDuration": 10,
    "IsPermanentRestore": false
}

Example: Change restore type to permanent

The following command changes the restore type for snapshot snap-01234567890abcedf from temporary to permanent.


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

The following is the command output.


{
    "SnapshotId": "snap-01234567890abcedf",
    "IsPermanentRestore": true
}

View archived snapshots

You can view storage tier information for snapshots using one of the following methods.

Console

To view storage tier information for a snapshot

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

In the navigation pane, choose Snapshots.
In the list of snapshots, select the snapshot and choose the Storage tier tab.

The tab provides the following information:
- Last tier change started on — The date and time when the last archive or restore was started.
- Tier change progress — The progress of the last archive or restore action, as a percentage.
- Storage tier — The storage tier for the snapshot. Always archive for archived snapshots, and standard for snapshots stored on the standard tier, including temporarily restored snapshots.
- Tiering status — The status of the last archive or restore action.
- Archive completed on — The date and time when the archive completed.
- Temporary restore expires on — The date and time when a temporarily restored snapshot is set to expire.

AWS CLI

To view archival information about an archived snapshot

Use the describe-snapshot-tier-status AWS CLI command. Specify the snapshot-id filter, and for the filter value, specify the snapshot ID. Alternatively, to view all archived snapshots, omit the filter.


$ aws ec2 describe-snapshot-tier-status --filters "Name=snapshot-id, Values=snapshot_id"

The output includes the following response parameters:

Status — The status of the snapshot. Always completed for archived snapshots. Only snapshots that are in the completed state can be archived.
LastTieringStartTime — The date and time that the archival process started, in UTC time format (YYYY-MM-DDTHH:MM:SSZ).
LastTieringOperationState — The current state of the archival process. Possible states include: archival-in-progress | archival-completed | archival-failed | permanent-restore-in-progress | permanent-restore-completed | permanent-restore-failed | temporary-restore-in-progress | temporary-restore-completed | temporary-restore-failed
LastTieringProgress — The progress of the snapshot archival process, as a percentage.
StorageTier — The storage tier for the snapshot. Always archive for archived snapshots, and standard for snapshots stored on the standard tier, including temporarily restored snapshots.
ArchivalCompleteTime — The date and time that the archival process completed, in UTC time format (YYYY-MM-DDTHH:MM:SSZ).

Example

The following command displays information about snapshot snap-01234567890abcedf.


$ aws ec2 describe-snapshot-tier-status --filters "Name=snapshot-id, Values=snap-01234567890abcedf"

The following is the command output.


{
    "SnapshotTierStatuses": [
        {
            "Status": "completed",
            "ArchivalCompleteTime": "2021-09-15T17:33:16.147Z",
            "LastTieringProgress": 100,
            "Tags": [],
            "VolumeId": "vol-01234567890abcedf",
            "LastTieringOperationState": "archival-completed",
            "StorageTier": "archive",
            "OwnerId": "123456789012",
            "SnapshotId": "snap-01234567890abcedf",
            "LastTieringStartTime": "2021-09-15T16:44:37.574Z"
        }
    ]
}

To view archived and standard tier snapshots

Use the describe-snapshot AWS CLI command. For --snapshot-ids, specify the ID of the snapshot view.


$ aws ec2 describe-snapshots --snapshot-ids snapshot_id

For example, the following command displays information about snapshot snap-01234567890abcedf.


$ aws ec2 describe-snapshots --snapshot-ids snap-01234567890abcedf

The following is the command output. The StorageTier response parameter indicates whether the snapshot is currently archived. archive indicates that the snapshot is currently archived and stored in the archive tier, and standard indicates that the snapshot is currently not archived and that it is stored in the standard tier.

In the following example output, only Snap A is archived. Snap B and Snap C are not archived.

Additionally, the RestoreExpiryTime response parameter is returned only for snapshots that are temporarily restored from the archive. It indicates when temporarily restored snapshots are to be automatically removed from the standard tier. It is not returned for snapshots that are permanently restored.

In the following example output, Snap C is temporarily restored, and it will be automatically removed from the standard tier at 2021-09-19T21:00:00.000Z (September 19, 2021 at 21:00 UTC).

            "StorageTier": "standard",
            "Tags": []
        }
    ]
}

To view only snapshots that are stored in the archive tier or the standard tier

Use the describe-snapshot AWS CLI command. Include the --filter option, for the filter name, specify storage-tier, and for the filter value specify either archive or standard.


$ aws ec2 describe-snapshots --filters "Name=storage-tier,Values=archive|standard"

For example, the following command displays only archived snapshots.


$ aws ec2 describe-snapshots --filters "Name=storage-tier,Values=archive"
