Reverting a Virtual Machine from a Snapshot

Before you Begin

Warnings:

  • It is recommended to verify the contents of the backup and ensure that you want to perform a revert operation as it is an irreversible operation.
  • If you plan to perform a revert operation, you will not be able to use the associated storage policy for further auxiliary copy operations.

On Windows clients, disable automount using the following command:

diskpart> automount disable

The hardware specific revert operation reverts the volume back to the pre-snap state.

For NetApp 7-Mode, if the volume being reverted is the source of a vault or of a mirror copy and if the protection topology is Primary-Vault, Primary-Mirror, or Primary-Vault-Mirror, the baseline snapshot on the primary volume will be shifted to the snapshot of the reverted volume. If the protection topology is Primary-Mirror-Vault or Primary-Mirror1-Mirror2, the baseline snapshot for Mirror-Vault and the baseline snapshot for Mirror1-Mirror2 are not shifted, which might lead to auxcopy job failures.

For NetApp C-Mode, the revert operation does not shift the baseline snapshot. If the revert operation results in the deletion of the baseline snapshot, the revert operation will fail.

The revert operation might delete some snapshots. To avoid failures, when selecting IntelliSnap jobs for auxcopy or backup copy operations, unpick all IntelliSnap jobs that have deleted snapshots as a result of a revert operation. Running auxcopy or backup copy operations with IntelliSnap jobs from deleted snapshots might produce failures.

The revert operation for virtual machines is supported on NetApp File Servers, but revert from SnapVault or SnapMirror snapshots are supported only for NetApp cluster mode (ONTAP version 8.3) and OnCommand unified manager (OCUM) version 6.2 or later. Other file servers are not supported. To perform a revert operation, the SnapRestore license is required on the NetApp file server.

Before performing a revert operation, ensure that all disks reside on the NetApp NFS data store. If the data does not reside on the NetApp NFS data store, you cannot perform the revert operation.
