This writes out the ssh config so the backup process uses the right key/user. Since we have a transition period where we have bup and borg backups we need to make the borg config have unique markers, or the two fight over the configuration block. Change-Id: I5455da3f2829e2aa8e0c531193adbbeff4b4776d
Configure a host to be backed up
This role setups a host to use borgp for backup to any
hosts in the borg-backup-server group.
A separate ssh key will be generated for root to connect to the backup server(s) and the host key for the backup servers will be accepted to the host.
The borg tool is installed and a cron job is setup to
run the backup periodically.
Note the borg-backup-server role must run after this to
create the user correctly on the backup server. This role sets a tuple
borg_user with the username and public key; the
borg-backup-server role uses this variable for each host in
the borg-backup group to initalise users.
Role Variables
The username to connect to the backup server. If this is left undefined, it will be automatically set to
borg-$(hostname)
