Have you made backups to this device before or is this the first attempt?
Is the target drive a usb external device?
If so, consider applying the usb rollup hotfix from
http://support.microsoft.com/?kbid=941600. This rollup will be part of
service pack 1 due out in about a month. This rollup is addressed in a
response to a thread on a very similar problem discussed at
http://groups.google.com/group/micro....gbl&lr=&hl=en
some months ago.
