Back up and restore a cloud volume

Last reviewed 2024-04-25 UTC

Protecting your data is an important aspect of data management. Cloud Volumes Service has the ability to send volumes of the CVS service type to Google Cloud Object Storage for long-term backup and archive. This data management feature complements volume snapshots, which provide access for development or test use cases that require short-term recovery. For more information, see Pricing.

You can only back up and restore volumes of the CVS service type. The service supports up to 10 concurrent backup or restore operations, and your client I/O may slow down during these operations. For better performance, you can use a larger pool size that supports greater throughput.

For examples that demonstrate how to use the API to program the automatic creation of backups, list backups, and restore from a backup, see Cloud Volumes APIs.

  6. Enter a name for the volume.

  7. In the Allocated capacity field, enter the size of the volume to create.

    The field is prepopulated with the size of the source volume.
