For off-site backup purposes I am looking at putting a NAS in 2 places (my own and another) and having them sync. This can be done with rsync obviously, but I'm looking for a bit more security data-wise
Instead of going for a RAID (high-availability) sollution, I was hoping to achieve a history/incremental/time-machine effect, but I'm unable to find if that can be achieved for both machine.
Lets say house A and House B both have a NAS with plenty space. House A gets an incremental/timemachine backup on House B's NAS, and House B gets on on the House A NAS.
Example would be the Time-Backup feature of Synology:
The problem is this sentence:
Please note that if you enable Time Backup Service on the destination server, the destination server can only provide Time Backup service as the backup destination.
I'm not completely sure what they mean, but it sounds like you can time-backup from A to B, but you cannot use that feature for a backup from B to A anymore?
Is there an off the shelf solution that enables me to do these kinds of backups from A to B and back?
(note: it is not a master-master situation where the files need to be merged. House A has their backup dir and House B has their backup dir, they need not be combined)
The initial wording might be confusing, but while a fancy mac-like "time machine" solution is great, it is probably enough to get some sort of snapshotting / incremental backup going. No need for too fancy stuff, just a "last week", "last month" kinda thing is enough.
