Veritas and Firewire Drive as backup on Compaq Server - slooooooowww!!

I have a w2k3 server with USB 1.0 ports. SUX. It has PCI-X slots so the only thing I could find for it was a firewire card. I am in the process of backing up and it is going to take 27 hours to backup 180 gigs at the current rate. In one hour it has only backed up 7 gigs of data.

At 400Mbits per second that should be 50 Megs a second x 60 = 300 megs per minute x 60 = 18 gigs per hour

It is taking nearly 3 times the amount of time it should take to abackup.

Any ideas?

Any other backup solutions? Want to get away from tapes but it seems to be my best solution.  My sdlt is doing 180 gigs in 11 hours but it is starting to flake out. Any good places to send it in for repair?

I didn't think W2k3 supported Firewire PCI-X cards? Maybe they are now. I will check the HAL if you provide the make/model reference.

If it is on the same bus as something running slower, then this may reduce the speed at which it can run.

Also, the speed of backup is not entirely dependent on the transfer rate of the backup media. This is usually the slowest point, due to the speed of physical tape/drives but not always. 180GB of data in few databases will be quick. 180GB of user files, word docs and TXT files will be very slow. If the external drive is formatted as NTFS (same version as server?) then at least there won't be too much conversion of pages but you need to read a fragmented file structure, defrag it, chunk it into pages of 4KB, then into 512KB blocks, then write out to a single HDD. The internal disk drive speed, bus speed, fragmentation, PCI bus speed, contention, AV (make sure it is not running), all add to the seen transfer rate.

Start at the source files, and work out to the external drive making sure everything is optimised.

Good luck and post your results
