Well, that is understandable... but i think, that rsync has major drawbacks: No history - overwriting means destroying (e.g. ransomware) || No deduplication - restic transfers blockwise and only once || No encryption - access to backup means access to all data || No error protection - how to verify backup success? In my opinion a good backup should contain a verified restore strategy :-) You should also consider sending and receiving snapshots, when using zfs (https://docs.oracle.com/cd/E18752_01/html/819-5461/gbchx.html https://docs.oracle.com/cd/E18752_01/html/819-5461/gbchx.htm...). Zfs also supports deduplication, but FreeNAS devs do not recommend using it unless you have a massive amount of RAM and you know what you are doing.
