Working with Snapshots and Undo Disks 153

Note. You cannot delete the root icon, but it gets automatically deleted after you delete all the

other snapshots.

To merge snapshots

Merging takes place automatically when you delete any snapshot except the last one in the

branch. When you delete an intermediate snapshot, the information it contains is merged to the

next snapshot of the same branch.

If you delete the snapshot belonging to two branches, the information is merged to the next

snapshot of each branch.

Note. If you delete the snapshot that comes after the root icon and that belongs to two branches,

the branches will start from the initial state icon directly.

Working with Undo Disks

The Undo Disks option allows users either commit or reverse the changes, that were made

during the current virtual machine session to its virtual disks. The current version of Parallels

Desktop allows applying this option only to all disks of the virtual machine at once.

Warning. Not all operations can be undone even if you enabled the Undo disks option.

Operations performed via the virtual machine, for example, changes made to Mac OS X files

cannot be discarded, transactions performed in the network data base cannot be canceled.

You can enable the Undo Disks option on the Advanced tab of Options in Configuration Editor.

For details, see Advanced Options (page 163).

When you set this option, you also have to choose the action performed on the virtual machine

shutdown:

1 Apply Changes

2 Discard changes
