I'm afraid that the short answer is: no

In most situations there should be no need to remove an intermediate backup because there would be little space saving. However in some situations it would be very helpful - say if you backed up the wrong stuff into an existing repository on one occasion (and then subsequently corrected it). Still, there is no easy way to fix this.

What can be done is to regress a repository day-by-day to get back beyond the 'bad' backup and then start anew from there. If the backup(s) you wish to remove are reasonably recent, and you don't mind losing any changes since then, this might be appropriate, and I have a script which can help (which I posted here a few weeks ago).

Hi there!

I'm a happy rdiff-backup user, this utility is really excellent. Great work!

But some backup partitions are getting full. Is there a possibility to
remove not only the oldest backups(s), but some backups in between? For my
/home directory, the last backup is most important of course, but I would
also like to be able to restore the very first backup I did make. All other
backups in between are not that important, and I would like to remove some.
But rdiff-backup only has a --remove-older-than<date>  option, not something
like --remove-between<date1>  <date2>. Is there some workaround, or do I
want the impossible?

I'm expecially concerned about one backup that has very much data in it that
was only temporary and is no longer needed. I read I could remove those
specific files if I am careful, but I still think there is an important
feature missing.
