BackupExec 2010 R3 on Windows Server 2003 SP2 Suddenly Slow thoughput
My Media server (backup server) is running
- Windows Server 2003 SP2
- BackupExec 2013 R3
- attached a SAN storage
- with HP tape library (LTO 4)
- Backup job included backup Local Disk, Virtual Disk (from SAN) and remote server
Two weeks before, the backup job rate is nromal, it running from ~3,000 MB/min
And, Now it drops to 180MB/min
I apply all the hotfix by "Live Update", disable "Removable Storage" service, reboot the server and Tape library.
But, no luck! no any improvement on the job rate!
I tested the network speed by copying a 4GB file between a remote server to media server, it is noraml and takes ~ 2 mins.
And, tested the I/O read/write on SAN by copying a 4GB file between SAN and the media server, it also noraml and takes < 2 mins.
Now, I found that BE takes over than 1 hrs, but still backing up a 8GB file!?!?
Does anyone have any idea to fix this problem?
Many Many Thanks!
