Hi,

I backed up my whole lightroom folder (includes all of the files and folders: Backups, Corrupt Catalogs, Lightroom Catalog.lrcat, Lightroom Catalog Previews.lrdata, Lightroom Catalog Helper.lrdata, Lightroom Catalog.lrcat-data, Lightroom Catalog.lrcat.lock, Photos Library.photoslibrary)

to a Dropbox folder (in the cloud), which I can access from finder as any other folder.

I'm using a Mac.

 

I entered LightroomC and chose "use a different catalog", and chose the catalog file (Lightroom Catalog.lrcat) from my dropbox folder.

 

Then the error appeared and said:

" The Lightroom catalog named “Lightroom Catalog” cannot be opened because of a data issue. Try to restore from a backup or open Lightroom Classic with a different catalog." (see picture)

 

How can I fix it?

 

Thanks!

Thanks for your help.

 

An update:

I realized Dropbox doesn't intergrate well wirh Lightroom (or should I say, Lightroom doesn't integrate well with cloud storage which isn't by Adobe). So I stopped working with Dropbox.

For backup, I use 2 external hard drives and one of them is backed up on the cloud.

Hi Daniel, 

 

Thanks for reaching out! We are sorry about the trouble with Lightroom Classic. We are here to help.

 

As the Lightroom catalog does not 'save' the images within itself and acts more like a database for the integrity and minimizing any chances of corruption or partial damage to the integrity of the catalog, it is advised to be only kept on the internal drive. Storing original images on the external drive is ideal in most cases. However, the catalog is sensitive and needs to be kept safe.

Your catalog is stored on a network/cloud storage. Please move it to the internal drive or desktop and try launching it. Please check here for more help related to Lightroom Classic Catalogs:  

https://helpx.adobe.com/lightroom-classic/kb/catalog-faq-lightroom.html

 

With the Lightroom Catalog file(.lrcat), other temporary support files and databases are actively handling important information. When you use a cloud sync service like Creative Cloud files, Dropbox, OneDrive, etc., all your files in the target folders are actively synced. In the case of temporary files, they might get duplicated and re-synced multiple times, and it risks the integrity of the Catalog database.

 

Understanding your workflow, you may require the projects to sync. In this case, in the future, you can pause the sync service and work on Lightroom Classic and only enable sync back once you are finished working in the catalog. It will allow the catalog to close itself and the required temporary files to go away and protect the integrity of the database.

 

To recover the corrupter/damaged catalog, you can create a new test catalog and merge the existing one with the new one to avoid broken or damaged databases. Copy the primary catalog or the catalog in question and place it on your computer's desktop.

  • When launching Lightroom Classic, press the Alt (Win) or OPT (macOS).
  • Choose the option to create a new catalog and create a new one on the internal drive.

  • In the new catalog, head to File > Import from Another Catalog, as shown below.

Proceed with merging the corrupted catalog into the newly made, internal storage-based catalog. 

For more help via video-based steps, check here. See Merging individual catalogs into a master catalog

 

Please let us know if this helps!  

Regards, 

Sameer K.

Copy and pasting a corrupted catalog does not eliminate the corruption.

 

You need to find a recent backup of your catalog file and put that on one of your hard disks (but not in the Dropbox folder).

 

Also, this makes me uncomfortable:

 

I backed up my whole lightroom folder (includes all of the files and folders: Backups,...


Backups should never be in the same folder (or even on the same disk) as the working catalog.

Hi,


Of course copy and pasting a corrupted catalog will not eliminate the corruption. It was just a test Sameer suggested to do.

In addition, can you please explain again your solution?

 

Regarding the backups in general, good to know (never heard of that before). If it is so dangerous, I wonder how come this is the default option...

Fot your concern, this is not the only backup I have, it's also backed up on hard drives.

how do I define the backup to be saved in a different location?

The majority of LrC customers only have one hard drive attached.

When the backup dialog appears, select a folder on a different disk.

 

In addition, can you please explain again your solution?

 

Find a recent backup of your catalog file, unzip it, place the unzipped backup catalog in a folder on any hard disk of your choosing, and then double click on it to open it.

So if you have over 2T of photos stored on external hard drives (since I'm working on a laptop), and the external hard drives are not reliable (for many reasons, also I'm moving between laptops so I used to carry the HD around- which is dangerous) - how would you editing and working with your photos?

Sounds to me that saving everything on the cloud and working with the cloud is the safest option, didn't it?

what would you do?

As you have seen, saving photos in Dropbox is not "safest", errors can creep in. Perhaps you want to share the photos in the Adobe cloud using Lightroom Classic. (I don't see people reporting these types of problems using the Adobe cloud). Then you can edit photos from wherever you are (as long as you have an internet connection).

Hi guys, thanks for your help. I opened the catalod from dropbox into LightroomC and stopped the sync.

 

Now I'm facing new question:

All of my folders (which I imported to loghtroom) are definited as "missing folder"s- which makes sense. 
I right clicked a folder >> chose "find missing folder" >> chose the right folder from dropbox >> clicked "choose".

Then, instead os just loading the photos: the folder disappeared.

How can I update the old folder to the one in the new location in this situation?

 

thanks!

it did not disappear. It moved to the new folder location where the photos are actually located. It is now elsewhere in the Folder Panel.

Hi, I got what you're saying, so I'll rephrase it:

let's take this folder for example:

Screen Shot 2022-05-12 at 18.35.32.png

 

 After I choose "fins missing folder" it shifts location (why does it appear on my macintosh and where- I don't know and would like to find out), all the files have this black mark:

Screen Shot 2022-05-12 at 18.37.11.png

As I click on it, it says:

What should I do?

Black circle exclamation point icons, and the error message you show, is a different problem. The file(s) has been corrupted somehow, and can't be used. You need to restore the file(s) from your backups.

It is possible that this is where the corruption comes from. Either the file gets corrupted somehow in the download process, or the file was corrupted in the upload process to the cloud. This unfortunately is a common problem with files stored in the cloud. Generally, I would not recommend using catalogs or photo files stored in the cloud.

Solution (not from Adobe, but from me) don't use photos in Lightroom Classic that are stored in a "cloud" folder such as DropBox or Google Drive or similar.
