Some would think this as a normal use-case for a cloud-drive.
But since 1Password backups seems to be using a format that Box.com won't upload, they are rejecting the files with this error:
> "Package files — Save as a flat file or a compressed ZIP file and reload"
It also means that you can't save .dmg-files.
I don't understand these limitations, Box.coms software feels rock-solid, and then I hit these strange limitations.
Dropbox on the other hand seems to allow all the filetypes I have thrown at them.
