Folders BreezeData and CAXMPFiles should be backed up as well as they contain the files generated from Face recognition and Auto Analysis. If you delete BreezeData folder, you would loose the learning that face recognition algo has made to suggest faces/people in your catalog.
Does the BreezeData folder contain the actual faces (coordinates of the box and the name of the person), or does it just contain the "learning data"? Or possibly the people tags?
Long time ago someone in this forum said what the "CAXMPFiles" acronym stood for, but I can't find that post anymore. Does anyone know what "CAXMP" stands for?
Most people use the built-in system in Organizer under the File menu. This works best with an external hard drive but CD/DVD disks can also be used.
File >> Backup
File >> Restore
You get a backup of the entire catalog database including your image files.
It’s all very well have in your own system backup but that can involve a lot of manual work in re-connecting the file paths used by Organizer.
