Data protection using SnapVault

SnapVault enables you to protect data on primary systems by maintaining a number of read-only versions of that data on a SnapVault secondary system and the SnapVault primary system.

The data that is backed up and restored through SnapVault depends on the primary system. On systems running Data ONTAP, a qtree is the basic unit of SnapVault backup and restore. SnapVault backs up specified qtrees on the primary system to associated qtrees on the SnapVault secondary system. If necessary, data is restored from the secondary qtrees to their associated primary qtrees. You can back up the qtrees from multiple primary systems to the associated qtrees on a single SnapVault secondary volume.
