Backup error 0x8004230F

[Guest]

I backed-up my personal files (not a Complete System Backup) on my system
last week using Vista's backup program, a USB 2.0 connection and a Maxtor
80GB portable hard drive. Everything got backed-up perfectly.

This week when I went to backup again, I get the error message:

"The backup did not complete successfully.

A shadow copy could not be created for the following reasons:
The shadow copy provider had an unexpected error while trying to process the
specified operation. (0x8004230F)."

Is there a solution for this? Should I wipe my backup drive and start again?
I have 4 USB ports on my laptop, does it matter if I plug into a different
port than last time (although it still reads it as the "F" drive).

Btw, I'm running Windows Vista Home Premium on an HP Pavillion dv9000 laptop.

If more info about my system is needed, please let me know.

Any help would be appreciated.

Thanks.

To anyone who is having the same problem, I fixed the error by simply
restarting the computer (something I realized after I posted that I hadn't
done since the default is just to put it into Sleep Mode).

Anyways, I restarted and the error message went away and I was able to
backup my system with no problems.

I have a new Gateway DX430S desktop with Vista Home Premium and experienced
the exact same thing when trying to Back Up to my external hard drive. I have
been putting my system to 'Sleep'.

Re-Starting the system solved the problem - thanks Toonartist!
