How to complete my BackupExec 2010 R2 backup on Windows 2008 R2
Posted on 2011-09-04
I replaced our old WIndows 2003 file server with a new Windows 2008 R2 file server. The new file server was a fresh install from scratch
and data (1 200 000 files, 580GB data) was copied with Robocopy.
The old server had a single 600 GB drive and the new one now has a system drive C:, 278 GB and a data drive D: (1 TB), both drives are implemented on separate RAID 10 arrays.
I used to backup the old server with BackupExec 2010 R3 without problems, however this is not the case with the new server: the job to backup drive D: aborts after some time with
Event 14, volsnap
"The shadow copies of volume "D:" were aborted because of an IO failure on volume "C:"." in the Event Viewer, BackupExec reports "V-79-57344-33928 - access denied".
A chkdsk of drive c: and D: reveals no errors.
I repeated the backup process and each time the backup gets further:
backup 1: 150 GB
backup 2: 156 GB
backup 3: 180 GB
backup 4: 185 GB
backup 5: 218 GB
backup 6: 244 GB
backup 7: 312 GB
backup 7: 329 GB
backup 7: 416 GB
backup 8: 463 GB
backup 9: currently running
Is volsnap in some kind of "learn" mode ?
How do I complete my backups reliable ?
