Manage VM snapshots

A snapshot is a replica of a VM as it was at the moment when you take the snapshot. Snapshot is a temporary disaster recovery solution. If the image file of a VM is corrupted or deleted by mistake, the snapshot data will also be lost. As a best practice, back up VMs if VM backup data is needed in the long run.

Application scenarios

Snapshots can be used for VM recovery when application software and VM OS incompatibility occur because of new application software installation, VM OS upgrade, or application software upgrade.

Restrictions and guidelines

As a best practice to avoid VM restoration failure, do not edit VM settings during the snapshot creation process.
