Adresse du projet: https://forge.centrale-marseille.fr/projects/sauvegardes

Features

• agent-less (ssh, /bin/sh, rsync or zfs)
• /bin/sh scripted
• server on FreeBSD/ZFS (may work elsewhere)
• clients tested: Linux/OpenBSD/FreeBSD (any unix-like OS should work)
• FreeBSD jails can be saved apart (and not depend on their host)

• fping
• mutt for reporting
• mbuffer advised (not mandatory)
