UNC backups excruciatingly slow

Created: 11 Jul 2013 • Updated: 12 Jul 2013 | 4 comments
This issue has been solved. See solution.

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 7.5.0.3 . a Win 2k8 media server also 7.5.0.3. 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.

2012 is now supported with 7.5.0.6 you can directly install and configure it and see how it helps to increase the backup performace.

Dont forget you can use the 7.5.0.6 Windows 2012 client on your client server without having to upgrade your Master or Media Servers yet - the 4th dot release no longer needs to match

Worth upgrading the Master and Media when you can though!

Hope this helps

Yeah that worked pretty well, I have to say im still not blown away with the speeds, but I understand that this is backup software not magic.
