    Need Advice: Ext USB HDD

    We have a IBM xSeries server running MSSQL 2000 and Legato's HSM software. Every night we back up our 12 G SQL database up to tape, but we would also like to make a disk backup of the database.

    I was thinking we could just attach an external USB hard drive and put a backup of the database on that every night as well.

    Any idea that would work? How long would it take to backup a 12 GB database across a USB cable?

    Yeah it would work....but I think it would take a while. I say get a Lacie Big Disk 500GB or something, which is Firewire 800...then pick up a firewire 800 card and away you go

    Only thing is that FW800 stuff is kinda expensive......but hellishly fast

    I just copied 40GB to my external which was USB 2.0 day before last and it didn't take too long, maybe 30 minutes or something, I don't remember for sure but it wasn't too long.

    yeah well it would depend on how quickly they want it done..but if it is over night its doesn't matter. Well USB 2.0 isn't that slow - isn't it actually faster than firewire 400? I thought USB2 was 480mbps compared to firewire 400 being 400mbps?

    How old is the server? Anything under 3 years old I would image would have USB 2.0.

    Can't you check through Device Manager? (sorry I can't think today )
