My "client" (good friend who says he will pay me when he starts making money ) has a 6+TB catalog and it is only going to get bigger Doing a catalog backup when LR shutdown takes a LOOOONG time and frequently crashes. Both issues I am convinced are related to LR creating a ZIP version of the catalog.
Catalog backups are now a separate disk (full backup of the LR data takes well over 12 hours, also on separate disks) so space is not an issue. How do I tell LR to STOP zipping the catalog backup ?
Unfortunately, There is no way to stop the zipping process of Lightroom backup catalog.
You cannot prevent the ZIPping of catalog backup.
There are also known problems with zipping files that are over 4 gig in size.
If your client's catalog (*.LrCat file) is really 6+gig (just the catalog file, not including the preview folders) then the workaround would be to break up that catalog into multiple ones that are less than 4 gig in size.
