LRC and One Drive sync issues

Lightroom Version Number

Hi
I started this thread as a question, but after starting to write this I have found a solution that works - so here is the process which I thought I would post as a resource for anyone having similar LRC sync issues.

I am running Lightroom Classic on a desktop with very fast broadband (approx 850Mbps download, 100 upload). I use One drive for all my images - no problems with these. I also have my catalogue stored on One Drive. Things were working fine until Lightroom crashed while I was in the middle of uploading a hundred or so images In April. I had to force a Lightroom shut down. I deleted the previous upload, started again and all seemed well. Since that time I have uploaded several thousand more images and done a large amount of keywording my older files. I currently have 47,500 images stored as DNG and JPEG, with some TIFFs and PSDs.

I am now noticing sync problems. I discovered that 4 files in the preview and smart previews folders were corrupted (they appear to be "empty".)
Please note that I incorrectly named my catalogue folder as Lightroom Classic backup. It is NOT a back up but is the main cataolue.

I tried to delete, copy/move or rename the individual problem files, but this was blocked. Finally I opened One Drive online, created a copy of the previews and smart previews folders and then disconnected my computer from One Drive. I successfully deleted the problem files online, and renamed the Smart previews folder(aiming to test with this folder first, before renaming the previews folder): Dead

I then reconnected the computer to One drive one line and let it resync over night. When I opened LRC it appeared to be successful.
(Although One Drive Work seems to have renamed itself One Drive Shared as we now use Sharepoint, so a separate non-LRCsync issue to solve!)

Here is what it looks like now, after opening LRC but changing nothing and then closing it again without requesting a backup.

It has worked!!

I have a similar sync problem with OneDrive. When I rename files in LrC the name changes happen in my Mac OneDrive folder but are not synced to OneDrive cloud. When I compare what's on my hard drive with Finder and what I see on the OneDrive website i can see the new names and the old ones.

If I use native Mac apps to change filenames, the changes are synced immediately and are the same in both locations. Of course LrC can then no longer find them and has to be repointed. Does LrC use some very low level method of changing filenames that doesn't get picked up by OneDrive software, perhaps? I don't think it's due to the latest LrC version as the name changes were made a version or two ago. Waiting overnight for a sync to happen does me no good.

My current fix for the problem is to repeat the renaming process via the OneDrive website, which is a bit of a pain. A bulk update process is available on Windows but I'm on Mac OS. I've emailed MS OneDrive support to see if they have any ideas. I'll update if there is any news.

The response from MS Support was that something interrupted OneDrive sync and that it couldn't subsequently identify it was incomplete.
The most effective solution is to perform a full OneDrive reset. The method is given at the following URL given to me by Microsoft Support.

Reset OneDrive



When OneDrive app is restarted, it performs a complete set-up including a complete synchronisation of ALL files. Depending on the number of files, this may take some time. How long it takes depends on network/ bandwidth and the number of files involved. Large amounts of data can easily take 24hrs+ to complete. Mine completed in approx. 6 hours and everything (including the Lrc Catalogue was as I expected to find it. Job done!
