I used to put my data on dropbox but I'm increasingly not comfortable putting my personal data on devices out of my control. Now I just do a daily local rsync backup. I also use syncthing to keep the documents, music and photos in sync between my laptop and phone (with all that, my phone's 128GB storage is less than 60% utilized).

Boxcryptor solves that problem for the most part... That being said, rsync works really well. I use it to copy files to and from the Synology.

I sync to a homeserver and back that up with Borg using a time4vps storage server.
