Vista Backup Error 0x81000014

[Guest]

I'm trying to use Vista Ultimate's File Backup to save data from a hard disk
partitioned in 2 partitions (OS and data).

C: 65GB full out of 124GB
D: 4GB full out of 120GB

Target is a 750GB USB drive.

The backup runs for a while, then fails with 0x81000014: "There is not
enough space on your Windows disk to prepare for backing up your files. At
least 400 MB of free space is required to continue."

I've tried searching all of Microsoft, and cannot find ANY reference to this
error. Googling shows that a few others have seen it, but no-one has a
resolution.

Any ideas or suggestions?

I wish I could say I could add something to this, but I'm having the same
problem and can't find any resolution, despite the fact that there are
unresolved postings on this subject in forums all over the place.

My source drive has 321GB free, so plenty of room for temp files. My
destination has 62GB free, more than enough for what I'm backing up and
certainly way more than 400 MB.

I guess I just want to add my plea in the hope that someone at MS will look
at this problem... I'm on the brink of spending money on a third party
product and that just stings.
