Furthermore I would like to understand the implications of running rdiff-backup-delete on the "timely window size" of rdiff-backup: By specifying the "window size" in rdiff-backup by the option "--force --remove-older-than" does rdiff-backup remove outdated "*.gz" files? The question could be relevant because rdiff-backup-delete opens "*.gz" files, drops history information and creates new "*,gz" files which will have a more recent time-stamp. Will there be a conflict with respect to the window-size? Could you also add your answer to the official rdiff-backup documentation.
The relevant date for files in rdiff-backup-data is the date that is part of the file name, e.g. "mirror_metadata.2022-06-15T21:08:20-05:00.snapshot.gz". The modification time for that file is irrelevant. -- Bob Nichols "NOSPAM" is really part of my email address. Do NOT delete it.
