It`s clear the back up did not finnish, because at the time there was a process running.
This can be a case when say you have an anti virus program that is memory resident.
In other words looking at changes in resident memory.
In short for a back up turn off all memory resident virus programs.
PS: Avg has one !
doesn't make any difference, thats what the shadowcopy mechanism resolves.
OP: do you have enough space to put the backup as it is being made?
