go to one cloud open your personal vault create a folder/s and back you everything there
I have One Drive Accounts. But when I go to my SECURE FOLDER, and click on Settings then go to Backup/Restore, I ONLY have my Samsung Account. I don't have the ability to change it from Samsung cloud to anything else.
I'd just as soon be able to get SmartSwitch to back up my secure data to my personal computer along with the REST of my files on my phone.
