Create backup from snapshot

A snapshot is a good base for creating a backup as its guaranteed to be static data. That is, once the snapshot is available (which is a fast procedure), no more writes will occur to the data in the snapshot, this assumes the integrity of the data stored, see Create snapshot.

More information on backups (which we recommend you to read) is available in our Backup article.

Note

Backups are just for volumes. You are not able to backup an image.
