Auto Snapshots

Automatically create snapshots of your VM on a schedule or at key lifecycle events.

Fields

Field	Description
Enable	Turn auto-snapshotting on or off for this VM.
Prefix	Text prefix added to the start of every auto-snapshot name (e.g. auto, backup). Helps distinguish automatic snapshots from manual ones in the Snapshots list.
Frequency	When to create the snapshot — On Start, Daily, Weekly, Monthly, or On Shutdown.
Retention	Maximum number of auto-snapshots to keep. When the limit is reached, the oldest auto-snapshot is deleted automatically before a new one is created.

Frequency Options

Option	When it runs
On Start	Every time the VM starts
Daily	Once per day when the VM is running
Weekly	Once per week when the VM is running
Monthly	Once per month when the VM is running
On Shutdown	Every time the VM shuts down or is stopped

Retention Strategy

The Retention count controls how many auto-snapshots are kept at any time. Once the limit is reached, the oldest auto-snapshot (matching the configured prefix) is removed before creating the new one.

For example, with a prefix of auto and retention of 7, you will always have the last 7 auto-snapshots available as a rolling backup window.

Tip: Use a unique prefix for auto-snapshots so manual snapshots are never accidentally removed by the retention cleanup.

Safety Snapshot on Restore

When restoring any snapshot, you can opt to create a safety snapshot of the current VM state first. This gives you a rollback point in case the restore doesn't go as expected. The option appears in the restore confirmation dialog.
