* Distributed backups
* Distributed/remote backups
Distributed backups are a better way of ensuring the persistence of your data, such that even if your system gets stolen or destroyed then the data will still be recoverable from your friends. Since the backups are encrypted your friends (or anyone else with access to their systems) won't be able to read your backed up content even if their systems are subsequently compromised.
Firstly you will need to have a user account on one or more of your friends servers. They don't necessarily need to be using Freedombone, just some version of GNU/Linux with ssh access. They can create a user account for you with the *adduser <username>* command when logged in as root and then give you the username and password via a secure method, such as on paper or via an encrypted email or via an XMPP chat using OTR. Make sure that the password used is a strong one - preferably a long random string stored in a password manager - so that dictionary attacks will not be easy. Also for maximum resilience put your password manager file onto a USB thumb drive and carry it with you.
