Set Up Automatic Snapshots with AutoProtect
Fusion can take snapshots of the state of a virtual machine automatically at set intervals, with the
AutoProtect function. This function is in addition to manual snapshots, which you can take at any time.
When you turn on AutoProtect, you set the maximum number of AutoProtect snapshots to keep at a time.
After this number is reached, Fusion deletes the oldest AutoProtect snapshot in the range to make room
for the newest snapshot.
This number setting can affect the number of manual snapshots that you can take and keep. You can
have no more than 100 snapshots for a virtual machine, and depending on the types and sizes of the
virtual disk files, this number can be less. If the total of AutoProtect snapshots reach the limit, you cannot
take manual snapshots.
Fusion uses this setting to estimate the minimum amount of hard disk space the AutoProtect snapshots
will use. That information appears at the bottom of the panel. The maximum amount of hard disk space
can be significantly more than the estimate, depending on the amount of changes you make between
snapshots.
Note When you have manual or AutoProtect snapshots of a virtual machine, you cannot add or modify
its virtual hard disk.
Procedure
1 Open a virtual machine, or select it in the Virtual Machine Library.
2 Select Virtual Machine > Snapshots.
3 Click AutoProtect Settings.
4 Select the Enable AutoProtect check box.
5 Select the frequency of snapshots.
6 Select the number of AutoProtect snapshots to retain.
After this number is reached, Fusion deletes the oldest AutoProtect snapshot in the range to make
room for the newest snapshot.
7 Click Done to apply the AutoProtect settings.
8 Close the Snapshots view and return to the virtual machine.
Prevent the Deletion of an AutoProtect Snapshot
When AutoProtect takes a new snapshot, it deletes the oldest snapshot to maintain the allowable number
that you set. You can prevent the deletion of an AutoProtect snapshot.
Procedure
1 In the Snapshots window, hover the cursor over the AutoProtect snapshot to keep, and click the
information button (i).
2 Click Keep Snapshot.
