Zut alors c'est vachement mal!
I was aware that backups were now being compressed.
I just tested my last back-up by double clicking on the folder.
On the menu bar I clicked Extract Files and it worked OK. So I can access the .lrcat file.
How are you unzipping? I’m using W7 Pro.
Wow. That's not good.
I'm unzipping using right click and Extract All with w7Pro. I must say that I've tried with W8.1 Home (on my laptop) with the same result. I must also say that my backups are on a NAS. I copy the archive on a local HD before unzipping. I'm currently restoring my online backup of the original catalog to see if I can get something out of it.
I'm not using NAS but hopefully you can unzip as the compression technology is quite basic.
I'm not really sure why Adobe decide to zip up back-ups.
The space saving is mostly negligible.
I've tried to unzip directly from the NAS with the same result.
You may have a point there when you say the place saving is mostly negligible. My Catalog weight 5GB and the Backups weight about 1GB. So there may be a problem with the backups, do you think ?
I always test catalog integrity before the backup.
There is a known problem with catalogs that are bigger than 4 GB. This results in a ZIP file that some ZIP utilities cannot open.
If this is the case for you, you will need a ZIP utility that does not have this limitation. "Stuffit" is one of the recommended utilities.
Actually my online backup has done the job. But I'll know when I'll want to unzip a catalog archive.
