Hi, thanks for the reply. What is the locking files issue? The file appeared to be the correct (latest) version by the date and time, but the content of the file was corrupted. i.e. Lightroom reports "this catalogue is corrupt and can't be opened' This has happened severally times. I could imagine part of the file is synced incorrectly while Lightroom is open and writing to the file, but surely once Lightroom is closed and the final file is synced the files on each computer should be identical?
I've been trialling Resilio Sync and haven't had much luck. I have two NAS servers in different locations that I want to keep in sync with a desktop PC and travel laptop. The main things I want to keep in sync are a 2.5TB photo collection and a Lightroom Catalogue. The Lightroom catalogue will only be used in on one machine at a time. I had various teething problems, but the main one is the Lightroom catalogue repeatedly gets corrupted, as reported by Lightroom. I been careful to make edits only on one machine, close down Lightroom and wait for the sync before using it on the other machi
