Actually it does matter to me. I do not want to rely on a chain of reverse diffs to reconstruct important files. My concern is that a disk error could render reconstruction impossible. I would like every version to remain as a self-contained snapshot. So, I want to use compression and snapshots only.
The documentation says that earlier states of files can be saved as copies or diffs. However there does not appear to be a run-time option to create copies. I looked at the python code in increment.py and it does not seem to have an option to create copies for regular files. Is there a way to force rdiff-backup to always create copies of earlier file versions?
