There are a lot of backup solutions, many scripts based of rsync. The problem is not a lot of them encrypt your data before syncing it. I have a USB hard drive and I want to backup my user folder /home/myuser/ to the external drive. What software will allow me to create incremental backups which are encrypted with relative ease

Why not just use full disk encryption on the disk? It'll be transparent to rsync, but your data will be encrypted. Here's how to do it.

+1 That's how I do it; works very well. –  sleske Mar 27 '11 at 19:17

Try Duply. It's commonly used over ftp but it also has a file:/// backup target scheme.

Duply works, but it's still somewhat clumsy. –  Daisetsu Apr 1 '11 at 17:51
