Deleting a version of a cloud snapshot

Edit online

A cloud volume can have multiple versions of snapshots on the cloud storage. If capacity on the cloud becomes limited, you can delete versions of the volume that are no longer necessary.

Before you delete a version of a snapshot, ensure that no snapshot or restore operations are in progress for the selected volume. In addition, ensure that the connection to the cloud service provider is online, so the deletion can be validated and completed on the cloud storage. Wait until these operations complete before you delete any snapshots that are associated with the volume. Deleting a backup generation (as opposed to canceling an in-progress backup) requires the connection to the cloud account to be available when the task is submitted in order to validate user input before you start an asynchronous delete operation.

Using the management GUI

Before you delete a version of a cloud snapshot, ensure that the connection to the cloud service provider is online by completing these steps:
  1. In the management GUI, select Settings > System > Transparent cloud tiering.
  2. On the Transparent cloud tiering page, verify that the state of the cloud connection is Online.
To delete a version of a cloud snapshot from the cloud storage, complete these steps:
  1. In the management GUI, select Volumes > Cloud Volumes.
  2. Right-click the cloud volumes and Manage Cloud Snapshots.
  3. Select the version of the snapshot and click Delete. Click Delete all to delete all snapshot versions from the cloud storage.

Using the command-line interface

Before you delete a version of a cloud snapshot, ensure that the connection to the cloud service provider is online by entering this command:
lsvolumebackupgeneration -volume volume_id_or_name  -uid volume_UID
where volume_id_or_name is either the name or ID of the cloud volume and volume_UID is the unique identifier (UID) for the volume. If you do not know the UID for the volume, use the lsvdisk command to determine the UID for the volume.

This command lists all the snapshot versions for the specified volume by their associated ID and the time stamp from when the snapshot was created on the cloud storage.

To delete a single snapshot version for a volume, enter the following command:
rmvolumebackupgeneration -volume volume_id_or_name -uid volume_UID -generation gen_id
where volume_id_or_name is either the name or ID of the cloud volume, volume_UID is the unique identifier of the cloud volume, and gen_id is the identifier of the version of a snapshot that you want to delete.
To delete all snapshot versions for a volume, enter the following command:
rmvolumebackupgeneration -volume volume_id_or_name -all
where volume_id_or_name is either the name or ID of the cloud volume.
