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?

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.

Sync multiple devices through a server running 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.
