Hi,
Yesterday night, an ArcServe backup on a single VM failed. Not the end of the world, happened before.
This morning, got an alert from a script I coded to look for *delta* files on our Datastore. A delta file was left there. We have for hard disk on this machine, and only one delta file stayed for one of those disk. Usually, all I do is create a new snapshot, delete all snapshot, and everything comes back to normal. This time, the delta file stayed there.
So I tried to create one more snapshot (With the quiesce) option, like mentioned in the vmware. It failed (Timed out). Damn 
Now I have delta files stuck there for all of our disks. Tried again with the quiesce options like 10 minutes after. Works. Delete all snapshots, works, but still stuck with those delta files.
Ok, the thing is, all those 00000?-delta files doesnt seem to be used, as the modification time stayed at the time of the snapshot.
And also, the .vmx file does not seem to point to those delta files. So maybe I could delete them safely??
Here's some info.
