Why is my SBS backup failing?

The goal I am trying to accomplish is:

On Monday, Wednesday, Friday at 1 AM, I want to back up to drive G.
On Tuesday, Thursday, Saturday at 1 AM, I want to back up to drive F.

I have 2 different schedule tasks setup to do this. Both drive G and drive F are external drives connected by USB. This had worked previously. I am using the NT backup utility that came with the SBS.

My backups have constantly been failing. It doesn't matter if it's scheduled or manually started. This is my latest SBS backup log of a manual backup. Any ideas or suggestions?

More information in the system event viewer on the same error that happened 3 different times.

Type: Error    
Time: 12:02:30 AM and 12:09:30 AM and 12:16:58 AM  
Source: VolSnap          
Event: 25

The shadow copies of volume G: were deleted because the shadow copy storage could not grow in time. Consider reducing the IO load on the system or choose a shadow copy storage volume that is not being shadow copied.


What does this mean?

Please have a read of the following article which seems to apply to your problem and request the hotfix, apply it and then see if that resolves the problem:
http://support.microsoft.com/kb/826936
It may be because you are writing to USB drives - which are slow(ish) to write to.

I have to wait until tomorrow to apply the hotfix. This is the log from last night (scheduled backup).

No problems - the logs don't seem to give much of a clue (to me anyway) as to the problem.

I figured out the issue was a hardware issue with not being able to access the external drive although I was able to access the external drive when I connected it to another computer. I changed the drive with a new one and I haven't had any issues since. Thanks for your help!
