I'm currently working on a disaster recovery plan using fsarchiver. I have very limited experience with it so far, but it had the features and social proof I was looking for.
I have so far used it to create offline filesystem backups of two volumes, one was LUKS encrypted (has to be manually "opened" with cryptsetup).
It can backup live filesystems which was important to me.
It's early days for my experience with this, but I'm sure others have used it and might chime in.
Just one warning. If doing live, think about state and test your restores. Just mention because things like databases and ecryptfs will not properly archive live. There are various ways around, but consider if you have concerns regarding getting really good complete backups taken at one point in time and on live systems.
