How long to backup 250GB using a USB2.0 Hard-Disk

[Big.Wayne]

Hi,

I just installed an external USB2.0 hard disk for a friend to backup his *My Documents* folder, he's got just shy of 250GB of personal data.

I'm using Norton Ghost 9.0 and set-it up to verify the backup after its finished, but it seems to take a *very* long time.

10 Hours & 42 Mins!!!!!!!!!!!!

As far as I can see the system is USB2.0 and is running WindowsXP SP2. I'm not sure how much of that time is the *verify* part (maybe that takes 5 hours?) but if anyone can quote me some transfer speeds that would be much appreciated, ta!

Hi smids,

thanks for reply. Hmm I'm not sure what type of process it is doing but the resulting file has a .v2i extension.

I'm wondering if maybe it's working at USB1.0 speed?, it appears to be set-up fine in device manager, although it's a VIA KT400 chipset.

Also is there any difference between the cable used for USB1.0 and USB2.0? because I used an old cable that was laying around instead of the one included with the drive?

basically it all depends on the processor how fast it compresses the data

Hi again,

yes that would make more sense, it's an XP2400+ (T-Bred I think) so maybe its just taking its time.

Still I never did a 250Gb backup before, maybe thats 5 hours + another 5 hours (or so) to *verify* the backup. Not to much of a problem because it only does the one big *base* backup once a week and thats been set for sunday night so that its all done and ready to go for business start 9am monday.

thanks again!
