Catalog Backup Compressed from one computer not Compressed from other computer

I have two computers running V13.2, one under Win10, the other under Win11. The Win11 version is compressing the catalog backups into ZIP files. The Win10 version is not compressing the catalog. Size should not be an issue, the Win10 catalog is 1.6GB, the Win11 catalog is 700MB. The backups are going to the same folder on my Synology NAS (subfolder for each computer).

I cannot find any reference to setting it one way or the other.

I am curious about your problem of 'no zip file created'.

Do a Googly search for this topic and you can find some posts like this-

"There might be because of limited privileges. Maybe you have no standard user access to the specific folder, it needs Administrator rights to access, so it fails when trying to create the compressed file. 7-zip, WinRAR and other utilities can be configured to always have Administrator rights, so they won't fail. Or some system files are corrupt. Run sfc /scannow and restart."

TBMK LrC makes and saves a copy of the Catalog (& the data file) to the chosen destination, then after writing the files to the destination they are compressed into the ZIP. It seems that Windows-10 is not capable of compressing the files and leaves them as they were saved.

As I originally stated, this is a folder on my Synology NAS, that I, as the user, have all rights for access from both the Win 10 and Win 11 computers. Also, the Win 11 desktop was a replacement for a Win 10 desktop that was also backing up to a ZIP file. The whole design of the backup process is a black box. One curiosity is why on earth you have to enter the backup dialog to be able to specify where the backup is going to be saved at? As a 40+ year software engineer, I find it all very strange.

"I find it all very strange" as do I, and following your thread out of interest. For a Synology NAS I have no experience so will leave future answers for the experts.

"why on earth you have to enter the backup dialog to be able to specify where the backup is going to be saved at?". The Destination you [Choose] in the Backup dialog is 'sticky', it becomes the default for every future catalog backup (performed by LrC). Only needs doing once in each Catalog.

This was not my experience when I switched from Win 10 to Win 11. Both produced .zip files. There is no option you can set here, the backups made by LightroomClassic have to be zipped.

Please show us screen captures (using the "Insert Photos" icon; do not attach files) of what you see in Windows Explorer. Please check and double check and triple check that the larger catalog file is truly a backup made by Lightroom Classic and not via other methods.

Yes, both folders are definitely the result of Catalog Backup (once a day when used). The ZIP version unpacks to the exact same file composition of the uncompressed backup.

To further clarify, the computer running Win 11 is a replacement for an older desktop that was running Win 10. I still have the backup files from the older desktop and they were also ZIP files.

And no, this is not an April Fools joke!
