P: Possible problem with catalog backup zip files

I reported elsewhere that when I tried to backup LR6CC, LR stopped responding part way through the backup process.

I've re-upgraded my LR5 catalog (95K images, about 2.5GB size), created all new standard previews, new prefs file, and cleared acr cache. Also turned GPU OFF.

When I now try to backup, it gets part way through Optimizing the catalog, and then the backup dialog says 'Not Responding'. If I use Task manager to end the process, I find that I do have backups, but both the fullsized and compressed versions.

However, after being called away from the computer while it was doing the backup again, I found that eventually LR did start responding again, and went on to optimize the previews catalog, and then finished. This time it had just left the compressed version of the catalog.

This problem didn't occur with a new small LR6 catalog.

Win8.1,32GB ram, x99 mobo, ssds and HDDs.

So the hitch ought to be easy to find??

The (free, available on Mac and Win) Stuffit Expander tool seems to be able to handle the problematic zip files better than the OS provided tools. At least in the cases I've seen.

Thanks for the additional feedback. We've been able to reproduce the issue internally. And the dev is investigating it. I'll let dev know there is potentially a mac issue as well.

I have the same problem; my 2.4GB (90K images) catalog results in a freeze part way through backup, leaving me with both the backed up uncompressed file and the compressed file. With a small catalog (100 images) it all works fine. Win8.1

Simon, I've got a user at LRF with a possibly-related issue. In his case the catalog backup stalls 3/4 of the way through the process. He's tried turning off the Optimise and Integrity Check options, but with the same result. It appears to be stalling in the zipping process. His catalog size is 4gb, hence my mentioning it here.

Are you already investigating such issues, or do you need a bug report raising?

Simon, I've got a Mac guy with the same problem - it's a 1.8GB ZIP that unzips to a cpgz file too. I've verified his file doesn't unzip properly on my machine this morning too, unless I use extra software.

Thank you for the feedback.

We're investigating this (https://forums.adobe.com/thread/1834199) internally. This appear to be a Windows only issue where the catalog is larger than 4GB.
