About volume reversion

This page provides an overview on snapshot-based volume reversion.

About volume reversion

Google Cloud NetApp Volumes lets you revert a volume to a previous state using the data captured in a snapshot. Volume reversion restores all the contents of a volume back to the point in time a snapshot was taken. During reversion, any snapshot created after the snapshot you're reverting to is lost. To maintain the data from those snapshots, we recommend that you create a new volume from a snapshot or restore specific data with snapshots instead.

Common use cases for volume reversion

You can revert a volume to test and upgrade applications or to fend off ransomware attacks. Volume reversion is similar to overwriting the volume with a backup, but only takes a few seconds. You can revert a volume to a snapshot independent of the size of the volume.


Consider the following aspects of volume reversion:

  • Volume reversion takes a few seconds and happens while the volume is online and used by clients.

  • Reverting a volume to a prior state deletes any snapshot data taken after the snapshot you're using for reversion and the operation is irreversible.

  • You can use snapshots to revert a volume to a prior state. You can't revert a volume that is in a replication relationship.


Volumes with replications should revert to the latest replication snapshot to maintain the replication. Reverting to an older snapshot breaks the replication process and to start again. To avoid potential data corruption, we recommend that you stop applications using the volume before you perform volume reversion.
