Backup Exec 9.1 not seeing second server on network
Posted on 2009-06-30
We have a Windows Server 2003 with Backup Exec 9.1 on it that backs up itself and 2 other servers across the network. The job runs to an LTO tape drive that seems to be working fine. Lately we have been getting failed jobs that are only backing up about 2/3 of the data (50 gb out of 75 approx.) and failing with "unable to attach" errors and "device cannot be found" errors. It appears that when the job goes to backup the other server it cannot back it up for some reason. Some examples of the errors are:
"snapshot error 0xfffffelf device cannot be found" \\(server name\drive)
"unable to attach to \\(same server) ofo initialization failure on \\same server\shadow copy components.
"ofo snapshot error ran out of memory"
This has been going on for 2 or 3 days. the advanced open file option is set to on with a lock.
The MS software shadow copy provider service and the volume shadow copy service are both set to manual and were both running on the server that was not being backed up as an MS article talked about. It does not appear to be a tape issue as other items on the main server and another server are backing up and the server is question is working and can be seen over the network from the backup server. Could it be related to users leaving files open at night as we have seen that before? Any help would be appreciated, thanks.
