Threeway sync

[michielper]

I am setting uop a three-way sync between a Windows 11 laptop, an Ubuntu 23.04 laptop and a NAS. The sync is not (yet) automatic so I run a two-way sync from either of the laptops with the (Linux based) NAS before and after making changes. If the synchronisation is purely based on file change dates, the clocks are in sync and file dates are retained when copying, this should work, I think. I would expect that FFS always selects the file with the latest date.
When FFS uses its own way of determining changes, then I dont know if this schedule would work.

What are your thoughts?

Regards, Michiel

Hi,

For fully automated multi-way/multi-system sync you can check out syncthing. It does only one thing. Real Time Sync. As I do, you'll still use FFS for backups and everything you use it for now. This would be in addition to using FFS. It's not a replacement, it simply does one thing really well in a multi-device environment. And, like FFS, you can use it on Mac, Linux, and Windows.

Spam? Mentions syncthing but then also RealTimeSync, which is part of the FFS bundle?

Regardless, to the OP, I would use two-way sync on both laptops. You would sync each laptop to the NAS directly. Once you get RTS configured on them, running a sync on one laptop to the NAS will be followed by an automatic sync on the other laptop to receive those changes. During school, I had four separate computers that all used two-way syncing to the same network location and it worked perfectly fine.
