Check out fsarchiver, you can do hot backups and it has built in compression. http://www.fsarchiver.org/live-backup/ http://www.fsarchiver.org/live-backup/ Someone above mentioned Veeam, which I love for windows, but haven't really tested on Linux. It's free, but not open source. I personally use rsync to btrfs, but it's not encrypted.
