Hi Damon,

This catches plenty of ppl :-)

Usually create and keep a blank file of appropriate size (I use 1G) in
the root of the backup dir.
Then later this can be deleted to free up space for just this problem.

If you don't care about the history then just delete the rdiff-backup
folder and manually remove any large files.
Then restart the backup using --force.

If you do care about the history then perhaps you have a larger spare
hdd or partition that the data could be copied to,
perform the `--removed-older-than`, check size and copy the data back.
Also if you really do care about the history then having a second copy
of the backup is a given (snapshot at known good points.)

Of course if your using vfs just add some more drive space.
I still stick to old fashioned fixed partitions.

The whole premise (and surely reason) for using rdiff-backup is that the
most recent data is the most
valuable and as the history goes back the value reduces.
