The main cloud services don’t even work natively (GoogleDrive, OneDrive, iCloud) basically the only mainstream choice is Dropbox. I tried to use Google Drive in Mint, and it’s a pain to get it to work, and usually it stops working after computer restarts.
Someone has a recommendation about how to handle these services?
You can use rclone
I second that.
With the additional advantage that rclone has modules like crypt and join, which allows you to keep your data encrypted no matter which cloud you use, gaining more cloud space by joining clouds, etc.
