Lightroom: Very slow or stopped syncing

For better or worse, I've moved all my photos to Lightroom CC and the cloud.  I moved them there through Lightroom CC so my originals are in the cloud and not smart previews.  I personally think Lightroom CC is almost good enough and with my photos being in the cloud and accessible from anywhere, it breaks my reliance on my iMac at home.  I'm onboard for that and can now work from my iPad Pro when traveling.  My biggest bug bare is going to be the lack of features for handling metadata, keyword tagging, and location data in Lightroom CC (worse on IOS than MacOS), but otherwise, happy days.

Though I'm going to try and use Lightroom CC even on my Mac, I figured that I'd start a new catalog in Lighroom CC Classic and sync all my photos from the Adobe cloud back down to my iMac so I can work on them in Lightroom CC Classic if I wanted to, and at the same time I'd get a local copy of all my photos that I can back up somewhere else besides Adobe (OneDrive for now).  This sounded good.

I have 12K or so photos and it has only downloaded about 1700 in about 24 hours and is now getting stuck.  Rebuilding the sync data helps a little bit, but not much. It will download another half dozen or so photos and get stuck again.  There are no errors in the status messages, it just says "downloading" and then lists a large list of photos it is downloading.  The status above my name in main screen says "Synicing 433 photos" and that number hasn't changed for some time.

Can I get some ideas or help on how to troubleshoot what is going on please?

Hi James,

When you open Lightroom preferences -> Lightroom Sync, do you see any sync activity happening ?
Is there any erroneous files that are not synced yet ?
Is the count between Lightroom CC and Lightroom Web (lightroom.adobe.com) same ?

Thanks,
Arjun

Thanks for the reply - I’ve been moving house so had no access to my desktop. I’ll reply properly when I have my study back up and running with access to my desktop.

OK.  My study is back up an running in the new place.

I inadvertently opened Lightroom CC 'Web' when messing around with Lightroom and there was a Sync Error collection or folder there with a number of images with sync problems.  Cool, didn't know that existed.  I found them all in my local Lightroom CC (i.e. not classic) folders and backed them up then deleted them via the web.  Lightroom Classic still wouldn't sync so I have deleted the new catalog I had created and started again.  I'm on a much slower Internet connection at my new place but Lightroom Classic is slowly syncing at the moment.  I will report back if I bump into the same problem again.

More details in case this helps anyone ...

One thing to know, after posting my original post I noticed Lightroom CC had 13 images that wouldn't sync and would just report 'syncing 13 images' and never complete.  Using filters to find the un-synced images resulted in no results.  Using the Option key when in the sync dialog box also resulted in no images being reported with problems.  After spotting the sync errors and cleaning them up in the web version of Lightroom CC the desktop version of Lightroom CC is happy.  I deleted about 100 images via Lightroom web, most of them were reporting an error that I needed to sync them from their original location (it gave the name of the laptop I had used a few years ago).  That laptop is long gone but I have the images so I just deleted them from the cloud via the sync error folder.  The ones I backed up where half a dozen or so that were current and the errors reported as being from my current desktop.  After deleting both the old and current photos that had issues everything seems OK with Lightroom CC, and the current images I deleted I re-imported.  All but one was already in Lightroom CC (even though I'd deleted them from the sync error folder).  The one that imported was one I had rejected and deleted previously so I deleted it again.  This is long winded, but the Web version and Desktop version of Lightroom CC seem to be happy now.  I haven't lost any photos in the exercise.  I will wait and see if Lighroom Classic is OK.

Is there any way to stop Lightroom Classic from downloading all the originals? I just want the smart previews.  When I originally posted I was going to use Classic as a way to 'backup' the cloud to my local disks, but I have found I can do that with the desktop version of Lightroom CC.  It very quickly copied all the originals from the cloud down to a local folder.  I don't want to end up with two copies of my originals on my local disks ... but can see occasions when I might want to use Classic still ...  I dont' think there is but asking just in case.

"Sync Issues" in Lr Web is quite new and seems to identify a rag bag of possible errors. I don't find it useful.

There is no way to stop Classic from downloading all the originals, and this is fine if you treat the LRCC (desktop) just like LRCC (mobile) and see it only as a way to get files up to the cloud and into Classic. In this scenario, you would verify that the files have arrived in Classic and could then delete the files that were in your phone's camera roll. Here you are regarding the files that arrived in Classic as the originals, and you delete the copies that you had imported into LRCC just like the files on a flash card.

Another approach is to sync files from Classic, which puts smart previews in the cloud, and then import the same files into LRCC. Adobe's server should recognise that the newly imported original matches the smart preview, and then would not download that file into Classic.

Adobe have allowed some communication between the different bits of the Lightroom world, but they haven’t sought to enable a seamless and efficient integration between the “LRCC ecosystem” and the big continent that is Classic. You can use them together if you know what you are doing and can handle the bumps in the road.
