UNC backups excruciatingly slow
Becuase of the lack of 2012 server support (I'm not going down the beta path just yet) I'm forced to back up large ammounts of data from 4 file servers via UNC. The problem is that the UNC policies are so incredibly slow its blowing out my backup windows.
A brief overview: I have a Centos master server running NetBackup 126.96.36.199 . a Win 2k8 media server also 188.8.131.52. Both are fiber attached to LTO6 drives. I'm using the Win2k8 media server as the client to back up UNC paths on 4x 2012 file servers with local raid 6 volumes.
Now, I know there are a thousand things non netbackup related that could be the issue but we're talking about 10Gb connected Dell 620 (media and file server) sitting right next to each other in a datacenter, why am I getting 17000 - 23450 KB per second on full backups and way, way worse speeds on differentials.
I also have NDMP backups from a Netapp, same LTO6 drives getting around 120MBps and a 2008 file server running a netbackup client getting reasonable speeds.
Thanks in advance.
