But if you just delete the most recent backup (ie the last one which
has failed) why would this effect any previous backups?

Is it possible to produce a list of all the new rdiff files created
in the rdiff-backup data directory during a backup so if it fails
you have a list of the new files which can then be easily removed
and the backup re-run?
