The Warm Showers Community is a free worldwide hospitality exchange for touring cyclists. People who are willing to host touring cyclists sign up and provide their contact information, and may occasionally have someone stay with them and share great stories and a drink.

irt-back is a python application that uses the libvirt API to safely shutdown, gzip, and restart guests.

The backup process logs to syslog for auditing and virt-back works great with cron for scheduling outages. Virt-back is in active development so feel free to give suggestions or branch the source.

virt-back has been placed in the public domain and the latest version may be downloaded here: https://bitbucket.org/russellballestrini/virt-back

If you're worried that you're not paranoid enough about your communications security and want to improve your OpSec, it is actually fairly easy to go "full-Sn*wden" with hardware storage of your PGP secret keys. The Yubico Yubikey-Neo and Neo-N USB tokens are a neat (and cheap) way to keep your keys locked in a hardware device rather than stored as a file on your harddrive. The hardware tokens are compatible with the OpenPGP card protocol, which recent versions of gnupg support out-of-the-box. All of the public-key cryptography happens inside the tamper-proof device, so your secret key is never decrypted in the memory nor stored on disk of your machine.
