Query to the upload sync features and possible feature wish

i am on vdj and i did a dry run with a small bit of my database and i noticed the connect to google option which seems to upload the actual music files and the gathered info...this may be impractical for some pro users...as i really only need the database files themselves to be backed up...as library size is huge and would run out of google drive storage...can there be a sort of checklist system to what is actually uploaded?

another question...is mixo able to detect changes(no matter how small a detail)...in the xml file?

if so..what is the process? does mixo have to do a total rescan or will it seek out updated info and auto update....if this is the case...mixo should have a fixed xml filepath input...(the database files are not always located in C:\Users\Documents\VirtualDJ folder if your music is on a different partition)so once the program starts...it browses internally to that filepath and checks for updates etc(i do not know if it does this already)
