Colleagues, as there's no rsync in Openwall, and it is a bit hard to run rdiff-backup which is in Python (and Python is not included into the distro), the only incremental backup method left is with GNU tar.
May be someone could make the http://openwall.info/wiki/internal/gnu-tar-incremental-backups wiki page a bit more verbose? As of now, it only describes the process on the 'ideology' level, so it is necessary to google up a lot of actual information to implement the same thing. What I'd be glad to see there are samples of actual tar commands, the authorized_keys file samples (with all these restriction directives), may be even crontab entries, and the involved scripts, if any. Thanks! -- Croco
