rsync - Aug 2018 - Sync multiple devices through a server running rsync in daemon mode

Hi, folks!

I have a question about rsync running in daemon mode.

Let's pretend that two mobile devices, X and Y, need to be synchronized by
means of a server, where the rsync is running in daemon mode. If the device
X starts synchronizing a file with the server and after a short while
(before the device X finishes its sync) the device Y also tries to sync
with (the same file), does the rsync daemon prevent the file corruption
keeping the device Y waiting for X finishes its sync?

Best regards,

Alexandre

It sounds like you are assuming that rsync can do a 2-way sync which it
can't and you are asking about collision detection which it doesn't
have.

Maybe you want something like unison or owncloud.

Also, if you are doing anything that requires write access or
authentication you probably don't want rsync in daemon mode.

Kevin, thank you for your suggestion. I will take a time to study the
Unison. Maybe it can be a solution.
