I'm surprised by this statement: regression takes a very long time, I wouldn't swear that deleting the files is faster, but that would be my expectation. Just to have a little bit of fact, I tried both actions on two copies of the same repo (the restoretest3 repo we use in our tests): $ time .../rdiff-backup-regress.sh -f /tmp/restoretest3.reg [...] real 0m0.368s user 0m0.299s sys 0m0.064s $ time rdiff-backup-delete /tmp/restoretest3.del/nochange [...] real 0m0.042s user 0m0.033s sys 0m0.009s It's of course impossible to generalize from such a small test but logically it makes sense that deleting takes ~10x less time: - deletion applies only to the unwanted files and their ancestors, and implies only finding and deleting impacted files. - regression requires finding all the files of the last generation, and recreating them from the current one, via delta generation, and then deleting the current generation (the mirror). This means calculating, writing and deleting files. As said, I can't tell for your specific setup but given that you have only one generation of the unwanted files, I guess that deletion will be also much faster than regression, unless you have good reasons to believe otherwise.
