I have an issue with one backup. Which appears to be a very slow system state/vss backup on the backup server itself.
A few weeks ago, almost a month now, the backup of my Backup Exec Server started taking 14 hours, when it should be taking an hour.
Found the culprit, what appeared to be a hang up on the vss/system state. At first I took it for an error, but no errors were being put in event logs, or being thrown by backup exec. The backups would finish, albeit very slowly, but with the normal job rates.
VSS list writers at first returned some [5] waiting for completion, no error...messages
I found the 'repair vss' routine, performed that, rebooted, no effect on job completion time. I created a new backup, tried selecting system state and it would sit with an hourglass...I decided to let it sit, and see if it would eventually allow me to select the system state contents. it did, after 10 minutes. same with vss. Checked list writers again, everything came up [1] stable.
I am looking at the backup now, it is snapshot processing of shadow copy components, the Job Rate keeps going up, and currently stands at 7244 mb/min, previously it was snapshot processing of D: at 2900 Mb/min, after already backing up 134G of data from the server.
Essentially System state/VSS appear to have a huge performance issue which I can't seem to figure is tied to anything because it isn't throwing any errors (eventlogs or be2010), just being extremely slow to access. All other backups being done from this server of other servers are normal.
