Depending on data being backed up and fragmentation of that data, it could extend the time a backup could take.
Also since you are backing up over the network, you may want to update your Broadcom NIC drivers. You can download them from the support.dell.com website. It may increase your throughput also.
Network congention could also slow down the backup time. You may want to configure a dedicated backup network.
I updated the drivers for the Broadcom NIC for both the 725N and the backup server using 3com 996B Nic (came with PV122T backup juke box).
The performance on 100mbit seems to have improved from the average of 125mb/min to around 175-200mb/min this is when backing up another server (PE4600 and exchange 5.5 28GB total).
But poor performance still existing when backing up 725N, there is no network congestion, because it is done off hours and I know no one is there at 4AM.
How can I force the 725N to go into 1000Mbit, Full Duplex, it only shows me 10/100 half/full duplex options and Auto.
What else should I be looking at? This really is bad because the 725N is our main storage server with over 140GB.
If I detail the performance of my 725N backups it might help. Up until recently we were running the server on a 100Mbit network connection. It was taking me 8.5 hours to backup 66GB's of data. Moving the server to 1000Mbits network connection improved things, I now backup 88GB's of data in 3.5 hours. Our NAS has a hardware raid ctrl, 1GB of memory, single 2.4GHz processor and the data drive is configured with RAID 5. We use Networker 7.0.
