I'm on version 12.2.1 of Parallels Desktop for Mac, running a Windows 10 VM. However, this problem has been present before version 12. On schedule, Parallels notifies me that a Snapshot is due and recommended. The program creates the new snapshot fairly quickly -- no problem. The PROBLEM is that it takes what seems like forever to delete an old snapshot before it starts to create the new one. The record for this is TWENTY-SEVEN minutes, but it always takes 10 minutes, at least. I can accomplish nothing during this long wait. I'm aware that I could postpone it, and sometimes I'm forced to do that, but I like to let it proceed so as not to forget to do it. It's just deleting an old file. WHY would it take SO long? Has anyone seen such a delay? Is there anything to remedy it?
