I've been fairly happy with it... though I'm not a heavy user. I've mostly used it to backup pictures and email.

I use rclone (http://rclone.org/) for my syncing email backups. It also supports a bunch of other storage backends, so it may be worthwhile checking out.

Edit: Rclone works from both Linux and the commandline... so it's extremely useful for serverside backups.

Unfortunately rclone doesn't support encryption (yet) though... so the cloud provider can see all your data - https://github.com/ncw/rclone/issues/219

(unless of course you manually encrypt it locally before upload)

Mmm... true. Though if you're truly paranoid then you'll never really trust anyone to encrypt your data. :) I use tools like attic (https://attic-backup.org/) to create encrypted snapshots of my backups.
