Do you think with ReadyDR on (I just discovered the pretty new & cool features around there !...), this could be achieved in real time (or nearly real time)?
ReadyDR isn't a "high availability" solution - which means that the backup repository needs to be restored before you can access individual files. It is quite efficient, so you probably should look at it. It backs up snapshots, so you'd need to make sure they were scheduled fairly often on the source share.
rsync-over-ssh is almost as efficient, and creates a copy of the share files. Snapshots won't be the same as they are on the original, but you can use snapshots to recover previously backed up versions.
Both should work. I have more experience with rsync (using it to back up my primary NAS to other NAS on site). I use cloud backup for disaster recovery (currently I'm using Crashplan for that). But your idea of backing up to an off-site NAS is perfectly sound, and lots of folks do it that way.
Okay, this sounds pretty exciting! I'll give it a try for sure, both rsync that I know and ReadyDR. Thanks for advices!
