Debian backup
bartok.debian.org alias backup.debian.org is Debian's backup machine.
Backup organisation
/org/backup.debian.org contains two directories, staging and backup. The latter contains the backup and is organised in directories with date directories that contain all the files from that particular day. The number of kept copies is configured in files in /etc/da-backup-manager/.
The /staging/ directory is used by the clients, i.e. the .debian.org hosts that have something valuable to backup. The contents of the particular directories is pushed from root to root@backup.debian.org via rsync via a restricted SSH session based on key-authentication.
Directories:

Adding new backup directories
- install da-backup on the client
- create a crontab that runs da-backup daily at some convenient time
- configure the directories in /etc/da-backup
- install the public host key of the server with a proper command in puppet modules/ssh/templates/authorized_keys.erb for bartok. Do a puppetrun on bartok. (This might get done automatically eventually.)
- configure how many copies of the directory should be kept in /etc/da-backup-manager/
- run da-backup -v on the client to see if it all works.
- Backup items should be called <host>/<directory>. Historically we also used services/<servicename>.
Consistency checks
- Run sudo -u nagios /usr/lib/nagios/plugins/dsa-check-dabackup-server
