It looks like the following line has been added to /Library/Backblaze.bzpkg/bzdata/bzexcluderules_mandatory.xml which excludes my Dropbox folder from getting backed up:
</bzexclusions><excludefname_rule plat="mac" osVers="*" ruleIsOptional="f" skipFirstCharThenStartsWith="*" contains_1="/users/username/dropbox/" contains_2="*" doesNotContain="*" endsWith="*" hasFileExtension="*" />
That is the exact path to my Dropbox folder, and I presume if I move my Dropbox folder this xml file will be updated to point to the new location. The top of the xml file states "Mandatory Exclusions: editing this file DOES NOT DO ANYTHING".
.git files seem to still be backing up on my machine, although they are hidden by default in the web restore (you must open Filters and enable Show Hidden Files). I don't see an option to show hidden files/folders in the Backblaze Restore app.
I wonder if OP didn't realise there was this _Show Hidden Files_ option and their .git was indeed backed up.
That would be nice, they'd be able to get their history back!

Try checking bzexcluderules_editable.xml. A few years ago, Backblaze would back up .git folders for Mac but not Windows. Not sure if this is still the case.
