Backup Exec 2010 R2 Slow Performance over WAN
Here is the situation...
Backup Exec 2010 R2 (fully patched/updated on Win 2008 R2 SP1) runs local backups of our servers nightly followed by a duplicate set to tape, everything runs great. On Saturdays, I try to do an off-site backup to one of our remote sites via 50mb fiber links.
For these remote backups, I've tried using a B2D folder mapped to a UNC path (\\remoteserver\share), and I also tried RMAL/ndmp (remote media agent for linux) using a virtual disk library, both with the same result. The problem is the backup (via either device) is always limited to about 8-11mb/sec (60-80MB/min), even though 50mb is available.
I've tested the throughput between multiple test sites varius ways, I can always get 40-50mb. The kicker is, while a job is running off-site at 60-80MB/min, I can start the same job 3 more times to fill up the remainder of the pipe, but a single job will not use up the bandwidth available.
So I'm stumped and symantec keeps closing my cases blaming enviornmental issues, any ideas?
