Lightroom Classic: Corrupt catalogue ...

I am on version 9 of Lightroom Classic having upgraded several days ago. Running on mac OS High Sierra

I have used the updated catalogue quite a bit with no issues. I either swapped to another catalogue or just closed Lightroom down and go a message along the lines of the catalogue needed to be checked. Then it went to repair mode. When attempting to open the catalogue now I get " The Lightroom catalogue "2019_lightroom-2" is corrupt and cannot be used or backed up until it is repaired etc.. " I click on "Repair Catalogue" and finally I get "Unfortunately, the catalogue named "2019 ... etc" cannot be repaired.

Just incase it was a machine based problem I copied the catalogue over to a laptop and the same problem arises.

Unfortunately I had not got a backup, But I still have the previous version of the catalogue which I copied into a separate directory and performed the upgrade on this and appears to be running ok and I have managed to back it up.  Obviously this catalogue does not contain the images I have recently added and worked on - some 3000. Which is a bit frustrating!

Although I am back up and running (with a little bit of work to do!), I am a little concerned as to what caused it in the first place - how it can be avoided in the future.

If you need any more info let me know.

Thanks

Robert

It can be avoided, next time, by turning on “Back up every time Lightroom closes” in Preferences. Then quit Lightroom at least every other day.

Almost all catalog corruptions come from:
  1. Power Failure
  2. Accidental Cable removal
  3. Impending hardware failure
  4. A brief issue in the early Lightroom 4 time frame.
  5. Syncing issues when storing a catalog on a syncing service (e.g. Dropbox)

Apart from backing up every time LR closes (something that regularly fails at my computer by the way, no matter what location I try to save it, and then next time it backs up fine), make sure you save changes to XMP sidecar files.
Then, if you have made changes that are not in your backup, it is still with the file and you can read the changes from the XMP files.
