I’m using Syncthing to keep several folder synced between my iMac with attached RAID and my laptop. In general it’s worked well but I have experienced a few problems with keeping my Lightroom Classic catalog (.lrcat) file properly synced. I’d like to share my setup for others and ask a couple questions.
Here is the ignore pattern I’m using:
// General purpose patterns (?d).DS_Store .Spotlight-V100 .Trashes ._* iPod Photo Cache
// Special to this folder with Lighroom and other photos // I want to sync these files in case I forget to quit Lightroom, blocks opening on other computer !Master.lrcat-shm !Master.lrcat-wal !Master.lrcat.lock
// Prevents sync of previews and cache files, build on local computer *.lrdata
// Don’t sync Mac Photos app library *.photoslibrary
I’m not syncing my previews. I build those with different settings on each computer.
Using the watcher and default scan interval seemed to be missing some changes. I’ve also noticed that the watcher can cause issues when Lightroom is building previews and the catalog files is being updated continually.
?? Is there way to tune the watcher’s sensitivity ??
For now, I’ve turned the watcher off and lowered the rescan interval to 300s.
?? Does setting the scan to low values cause problems ??
If I don’t explicitly list the Maser.lrdata file then if it’s open on one computer it doesn’t sync to the other computer.
?? Does Syncthing know that a file is in use ??
