BackupExec backup to disk speed
Posted on 2009-02-19
I'm just looking for some feedback from others using something similar to this.
Basically I have a server with about 1.5TB of data (your average day-to-day data with lots of different sized files). I have a second server with BackupExec 12.5 installed, lots of SATA disk space and an Ultrium LTO4 connected. What I want to do is disk-disk backup from the production server to my disk backup server, then from there onto tape. I have a crossover cable between the servers to give 1gb LAN connectivity.
I have my policy setup to do a full backup-to-disk job one day a week then differentials the other, and then duplicate jobs to automatically copy the data from the backup-to-disk-folder onto tape. This all works perfectly in theory, the problem is the speed of the disk-disk part across the LAN. The data shoots onto the tape at 2-3000mb/min no problem, but coming across the LAN for the disk-disk part it runs at 250mb/min. Doing the math on that it will take 4-5 days to complete a full backup, I'll then get a couple of differentials in and be back to another 4-5 days. No really feasible.
So my questions are -
- is 250mb/min normal enough in this scenario, am I flogging a dead horse with this particular method?
- what other ways are there without spending a lot of money? The production server is on a fibre attached MSA1000 SAN by the way, it's a DL380 server. The disk backup server is a DL320S.
All thoughts appreciated!
