These instructions are meant as a disaster recovery strategy in case all of FSFE's infrastructure collapses and a complete recovery of all servers are needed, including the backup server.
1. Setup a pristine Debian with duplicity on a new virtual or physical server.
2. Restore cleve's file system and keys either from the most current backup, or if really needed, from the directory ssh_keys/ and gpg_keys/ To restore cleve from Hetzner:
remotepass=<see documentation> remote=sftp://u124410:$email@example.com/ duplicity restore $remote/cleve /<restore_point>
This will ask you for the password for the GnuPG key, so you need to have this in hand.
3. Restore other machines in a similar way.
