The destination we are backing up to is a QNAP NAS box with capacity of 20TB. In total the virtual machines we are backing up are about 14TB.
Backups have been running fine for a few months but today we were having issues about the destination running out of disk space. We were also getting error messages about the meta data being corrupted. I've freed up some space by deleting some of the older VRB files and started new backup sets as per http://www.veeam.com/kb1885
. I'm going through our backup jobs and running them manually one by one and currently having no more issues backing up. I'm also removing the old vbk files once the backup has completed to free up even more space and basically starting again.
I am guessing that the number of VRB files got so big it took up all the space making the backups fail? Is there a way to limit the number of VRB files? Or should these automatically be deleted once we start running out of space?
