Backup manager manages volume backups.
Volume Backups are full copies of persistent volumes stored in a backup store e.g. an object store or any other backup store if and when support is added. They are usable without the original object being available. A volume backup can be restored to the original volume it was created from or any other available volume with a minimum size of the original volume. Volume backups can be created, restored, deleted and listed.
