Slow backup performance on Cisco Call Manager and Unity
We have a Cisco CM 4.1 with a PUB and SUB.
We back these up nightly with EMC (Legato) Networker.
The issue is these three (One is Unity) back up about 10 times slower than any of my other Windows servers. I do not see any performance issues on any server. The network connections on all are 1gps going to catalyst switches.
The difference is that they are on a different VLAN than the rest of my data. That is the only difference I can find. It may be irrelevant.
Anyone got any ideas?
Thanks

It has always taken longer. It isn't so much how much data, it is the rate at which it is backing up. All three of these servers have the least amount of data of all my servers.
I think the backup rate is about 600KBS. My normal Windows servers are around 8MBS. The more I think about it, the more I am believing it is a traffic throttling thing in my switch. Cisco 3560 I think.

ya if you have qos or any type of throttling that would make perfect sense.
How much work would it be to directly connect to the device and perform a backup. Would be nice to rule out switching/qos

I could do that but I think I will skip ruling out the Qos and see if I can rule it in. I think I will kick off the backup and then remove some srr entries in the port settings. I just want to see if that is it, I am guessing it is. If so, then I need to determine if I have to have those settings or if the default Qos should be enough. But that is getting the cart in front of the horse.

The layer 3 is being done on the switch.

How much data is being backed up? And approximately how long is it taking?
