Hello!

Today I tried to delete one of VM's checkpoints in Hyper-V on Windows Server 2012 R2 and got the error "Deleting failed...". I then tried to delete all checkpoints to start a new checkpoint tree but failed again: I was able to delete all checkpoints except the faulty one:

Why this checkpoint can not be deleted? In this situation no subsequent checkpoints can be regarded as fully functional because all of them will be "under" the faulty one.

I never had this problem in Windows Server 2012 (not R2).

By the way, what's the purpose of renaming snapshots to checkpoints in R2?

Thank you in advance,

Michael

Hi,

I cant find out the similar issue. Please try to disable the AV soft, if you are using the WSS backup please after the WSS finish then delete again.

Hope this helps

Hi Alex, thank you for the reply!

This problem occurs on a test server, it has neither AV nor backups, but I'll try to make a backup and delete the snapshot again.
