I'm also quite pleased with borg. I haven't had to do any full restores with it, but minor testing of restores and backing up has been a breeze. One aspect is that I'm using a different repository for each host, so my system files and other duplicated files are not deduplicated between the per-host backup repository, but with each incremental backup I do see quite good deduplication results. The deltas between runs (of the same host, of course) are usually quite small. > > > [0] https://borgbackup.readthedocs.io/en/stable/ > > > ___________________________________________________________________________ > Philadelphia Linux Users Group -- http://www.phillylinux.org > Announcements - http://lists.phillylinux.org/mailman/listinfo/plug-announce > General Discussion -- http://lists.phillylinux.org/mailman/listinfo/plug ___________________________________________________________________________ Philadelphia Linux Users Group -- http://www.phillylinux.org Announcements - http://lists.phillylinux.org/mailman/listinfo/plug-announce General Discussion -- http://lists.phillylinux.org/mailman/listinfo/plug
