I am getting the following message when I attempt too back up:

1778685478467.png


I have tried backing up to other drives with the same result.

My external HD is 4 TB and I have 3.65 TB available so the size can’t be the issue.

I looked online and I am not finding a solution that works.

Any suggestions?

This is a known issue caused by catalog corruption. What you could try is this: Create a brand new catalog (‘File - New Catalog’) and choose 'File - Import from Another Catalog'. Select your old catalog to import. In the import dialog choose to import all photos, but do not move them. This will create an exact copy of your old catalog, but usually without the corruption. The only thing that won't come across is any publishing services you may have. You will have to recreate those. If you synced your catalog then you will have to enable sync for the new catalog. There are some reports that this could cause a problem. Here’s how to solve that: https://www.danhartfordphoto.com/bl...problems-caused-by-switching-the-sync-catalog

Wouldn’t a safer first step be to create a new catalog withOUT importing from the old one, import a few photos and then try to back up, to eliminate the possibility that it isn’t catalog corruption causing the issue?

This worked. The new catalog backs up just fine. The only issue is that myost of my Collectionms did not copy over. How can I get these into the new Catalog?

All your collections should come over if you follow the procedure correctly, except collections with zero images. Make sure you import all images (but don't move them). Because importing from another catalog is not the same as 'importing a catalog' (technically you are importing images, with all their catalog entries), collections must contain at least one image to come over.

No, because nothing happens to the old catalog. I would save some time, but it would not be ‘safer’.

I created a new catalog. I followed instructions. But almost all of y Collections failed to copy over to the new catalog. I cannot figure this out. Getting super frustrated.
