Can I recover a VM if a snapshot has been performed prior to the VM being corrupted?

If a VM becomes corrupt and the OS will not start after patching it, can I recover the VM if I took a snapshot of it prior to patching the VM? How would I restore the snapshot? Will it restore to the state it was in prior to patching it? How much space does a snapshot generally use up? We are running vSphere 5.5.

If the VM is a domain controller, don't revert the snapshot. The USN number will go out of sequence and then you will have to demote and promote it back as the domain controller

Some systems that I have created snapshots for last Thurs were having issues over the weekend. Come to find out, snapshots that were created were taking up disk space. I removed the snapshots from snapshot manager, which i believe fixed the issues with these servers. Is there anything more I need to do other than deleting the snapshot's I have created? Is it best practice to remove these snapshots after a day? Do these snapshots write to disk on the server, or on the SAN the server resides on?
