SnapVault archiving

SnapVault is archiving technology, designed for disk-to-disk Snapshot copy replication for standards compliance and other governance-related purposes. In contrast to a SnapMirror relationship, in which the destination usually contains only the Snapshot copies currently in the source volume, a SnapVault destination typically retains point-in-time Snapshot copies created over a much longer period.

You might want to keep monthly Snapshot copies of your data over a 20-year span, for example, to comply with government accounting regulations for your business. Since there is no requirement to serve data from vault storage, you can use slower, less expensive disks on the destination system.

As with SnapMirror, SnapVault performs a baseline transfer the first time you invoke it. It makes a Snapshot copy of the source volume, then transfers the copy and the data blocks it references to the destination volume. Unlike SnapMirror, SnapVault does not include older Snapshot copies in the baseline.

Updates are asynchronous, following the schedule you configure. The rules you define in the policy for the relationship identify which new Snapshot copies to include in updates and how many copies to retain. The labels defined in the policy ("monthly," for example) must match one or more labels defined in the Snapshot policy on the source. Otherwise, replication fails.

Note: SnapMirror and SnapVault share the same command infrastructure. You specify which method you want to use when you create a policy. Both methods require peered clusters and peered SVMs.

NetApp Data Availability Services and support for traditional backups

SnapVault data protection relationships are disk-to-disk, ONTAP-to-ONTAP. Traditional backups, and now backup to the cloud with NetApp Data Availability Services, offer less expensive alternatives for long-term data retention.

Beginning with ONTAP 9.5, you can back up volumes to the cloud using NetApp Data Availability Services, a cloud-based service for managing data protection workflows from ONTAP primary to secondary storage systems to the cloud.

NetApp Documentation: NetApp Data Availability Services

In earlier ONTAP 9 releases, the Cloud Backup Service feature allows NetApp Cloud Volumes Service for AWS customers to protect volumes to AWS object storage. Data that has been backed up to the cloud can be restored to any storage array in the fabric. Fast and easy retrieval from the cloud eliminates the requirement for tape-based backup in most use cases.

Numerous vendors offer traditional backup for ONTAP-managed data. Veeam, Veritas, Syncsort, and Commvault, among others, all offer integrated backup for ONTAP systems.
