This page provides details about volume backups.
About volume backups
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.
When you create the first backup of a volume, all of the volume's used data is sent to the backup vault. Subsequent backups of the same volume only include data that has changed from the previous backup. This allows for fast incremental-forever backups and reduces the required capacity inside the backup vault.
You can create manual and scheduled backups. Manual backups can be taken from a volume or from an existing volume snapshot. Scheduled backups require a backup policy.
Considerations
Backups aren't supported for volumes protected with customer-managed encryption keys (CMEK).
Backups aren't supported in conjunction with the cross-region replication feature. Attempting to create a backup of replicated volumes or attempting to set up replication on a volume that has a backup vault associated with it can lead to backup creation failure.
Backups aren't supported for projects in a VPC Service Controls perimeter. Attempting to create a manual backup will fail. Creating a backup schedule will appear to succeed, but no backups will get created subsequently. Reach out to Cloud Customer Care to get a temporary workaround solution.
About backup vaults
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.
About backup policies
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.
Volume backup workflow
You must complete the following steps to successfully set up volume backups for NetApp Volumes:
Choose where to store your backups by creating a backup vault for your volume's region.
Choose when to back up your data by creating a backup policy (schedule) to capture how many daily, hourly, and weekly backup versions to retain. This action isn't required for manually triggered backups.
