NetApp Volumes supports volume backups, which are copies of your volumes
stored independently from the volume. Backups are stored in backup vaults,
which are containers for backups. If a volume is lost or deleted, you can
use backups to restore your data to a new volume.
A backup policy is used to schedule backups at regular daily, weekly, or monthly intervals.
Backup policies allow you to attach a backup schedule to a volume.
The policy defines how many backups to retain at daily, weekly, or monthly intervals.
A backup vault is the location where backups are stored. You can only create one backup vault per region.
A vault can hold multiple backups for multiple volumes in that region.
Hostgroups define the hosts (aka initiators) that can access the specific Google Cloud Netapp Volumes.
Hostgroup is a regional resource and independent of the volumes or any other resource
Volume replication creates an asynchronous mirror of a volume in a different location. This capability
lets you use the replicated volume for critical application activity in case of a location-wide outage
or disaster.
NetApp Volumes helps you manage your data usage with snapshots that can quickly restore lost data.
Snapshots are point-in-time versions of your volume's content. They are resources of volumes and are
instant captures of your data that consume space only for modified data. Because data changes over
time, snapshots usually consume more space as they get older.
NetApp Volumes volumes use just-in-time copy-on-write so that unmodified files in snapshots don't
consume any of the volume's capacity.
