How to lock a snapshot in VMware?

  • 772

We have created a VM and took a snapshot.

Then we made changes in that VM and made it as domain controller. That state also saved in snapshot.

Now i want to lock the snapshot. My intention is that i should not deleted that snapshot by mistake.

Is it possible to lock the snapshot? Or if i delete all snapshots, will it be merged with base VM?

  1. Those snapshots are useless. If you ever try to revert a domain controller VM to an older snapshot, it will wreak havoc on the rest of the Active Directory.

    That said, there is no way (at least that I am aware of) to "lock" a snapshot so that nobody can delete it.

  2. You could use the DCUI and change the permissions of the snap file but really DON'T do this, it would be deeply stupid.

  3. To add to the previous answers, snapshots should not be used long-term. They are ideal for testing changes over the short term (hours, days, maybe weeks). But keeping snapshots long term impacts VM performance, and can even fill up a datastore with delta files.

    Snapshots != backups.
