This is not an online backup, however using this, you can use any backup provider safely, while considering him insecure - as you always should for third party closed source solutions.

Bandwidth and space efficient
Duplicity uses the rsync algorithm so only the changed parts of files are sent to the archive when doing an incremental backup. For instance, if a long log file increases by just a few lines of text, a small diff will be sent to and saved in the archive. Other backup programs may save a complete copy of the file.

Pro
•••
Encrypted locally before sending (using GnuPG)
Data is encrypted locally before being sent, and kept encrypted by a key that is never stored on the remote machine. So you might even store your data on a public space, people would still need your key or brute force it.

Easy for non-technical users
CrashPlan is easy to install and manage, but still secure and featureful. It uses client-side Blowfish encryption. Just install it, select the directories you want tracked, and forget about it. Weekly email updates let you know that everything's working fine, and alert you when things go wrong.

Memory-hungry Java service
This application exemplifies many of the negative stereotypes of Java applications. Both the backend service and the front-end management utility are written in Java. The backend service can get pretty memory hungry if you have a lot of files in the tracked directories. It's also prone to occasionally segfaulting out of the blue. Luckily, CrashPlan notifies you if the service hasn't checked in for three consecutive days, so you're warned that there's a problem and it's a simple matter of restarting the service. Still, it would be nice if it were less resource hungry and more stable.

Forces to use their (somewhat costly) storage
$0.25 / GB-month storage + $0.25 / GB transmitted sounds more than other solutions (like Google Cloud nearline storage which costs $0.01 / GB-month storage).

As long as I've tried Mega, I've tried to get dotfiles and -directories to show. I could never get it going. I also asked them about this, but I never got a reply.
