Hi there,

Currently running backup exec 2010R2 on our file server

3 drives on the file server are iSCSI volumes, each iSCSI volume comes off a separate port on the NAS, each one is configured to use a different subnet, in this case:
172.18.69.2
172.18.67.2
172.18.73.2

The file server has two network connections, one to the same subnet as all the servers, and another connection the iSCSI comes in on with an IP of 172.18.67.3

When running a backup through backup exec the backup of exchange, vmware hosts etc is all nice and quick (2000-2500mb/min) but as soon as it hits the backup of 2 of these 3 (only 2 are backed up) volumes it hits a sudden decline down to 500mb/min which is woefully slow!!

Now that I've looked over the settings, i know it's not setup efficiently and i could switch it around to be much better.......naturally i work all this out the day the kids come back so I can't actually do any of it right now!! >_< but even with that in mind it shouldn't be going 500mb/min, does anyone have any ideas as to what could be causing this?
