About Restore Operations


Explains what the feature is or what its benefits are to the user or customer.


When restoring to a running cluster that has not been updated, you'll usually use a snapshot. But in the case where you've updated the cluster to a new release, the configuration has been changed significantly, or you're restoring to a different cluster, you'll need to restore from a backup.

Snapshots are restored onto a running cluster, while backups require deleting the existing cluster first.

Snapshot restore is not backward compatible. As such, if you’re running version 3.0 you can restore from a version 2.5 snapshot, but not the other way around. If you need to restore a 3.0 snapshot to a cluster running an older version, you must first do a cluster update to version 3.0 and then restore the 3.0 snapshot on that cluster.

Changes to a cluster that require restoring from a backup instead of a snapshot include:
  • Addition or removal of a node.
  • Hardware upgrade.
  • Restoring to a different cluster from the one where the snapshot/backup was taken.
  • Restoring to a cluster running a different release from the one where the snapshot/backup was taken.
