The ssh config file is /.ssh/config (not ssh_config) We are accepting the ed25519 key, not the ecdsa key, so fix that in the known_hosts stanza. Change-Id: If3a42a7872f5d5e7a2bf9c3b5184fb14d43e6a1a
Configure a host to be backed up
This role setups a host to use bup for backup to any
hosts in the 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 bup tool is installed and a cron job is setup to run
the backup periodically.
Note the backup-server role must run after this to
create the user correctly on the backup server. This role sets a tuple
bup_user with the username and public key; the
backup-server role uses this variable for each host in the
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
bup-$(hostname)
