Gestion des sauvegardes de catalogue LR

You must be careful.

It seems that you have opened a Catalog  shown in Blue in your Backups Folder.

IF  {Lightroom Catalog-2-2.lrcat} shown in Blue below- is your current Catalog then you should move it (with the .lrdata folders) out of the {Backups} folder to a better location on your Hard-drive such as your {Pictures} folder. (Then Double-click to open)

Do you have another current working Catalog in another Folder that does not show in your screen-clip?

The Catalog in RED is either a very new Catalog or a very old one. Without opening I cannot tell- it could be deleted.

The Folder in GREEN is a .ZIP Backup from 2019-11-19 that should be preserved if you want at least one backup.

In the end result you should have-

1. Your working Catalog {Lightroom Catalog-2-2.lrcat ?} in your {Pictures} folder, or other preferred location.

2. Only Backup 'Dated' Folders in the {Backups} folder,

And most importantly- Change you Backups to another physical hard-drive. They would be lost with your working Catalog if this one drive failed- you would lose EVERYTHING in the Catalogs!

Using Finder to locate, can you post a screen-clip of your ZIP file Backups ?

Do you actually know where your Catalog Backups have been saving?

Did you perhaps delete a file with the file-type suffix of .LRDATA ?

Do NOT try any Import process!!
