If borg sees an ansible tmp file just before it is removed by ansible then we can get errors of this form when running borg: stat: [Errno 2] No such file or directory: '/root/.ansible/tmp/ansible-tmp-$IDENTIFIER' This causes the backup run to report failure. Address this by adding /root/.ansible/tmp/* to our borg backup excludes list. Change-Id: Ie2c7081a4510959f6514b1cb7eb8facc4ac129fb
Configure a host to be backed up
This role setups a host to use borgp for backup to any
hosts in the borg-backup-server group.
A separate ssh key will be generated for root to connect to the backup server(s) and the host key for the backup servers will be accepted to the host.
The borg tool is installed and a cron job is setup to
run the backup periodically.
Note the borg-backup-server role must run after this to
create the user correctly on the backup server. This role sets a tuple
borg_user with the username and public key; the
borg-backup-server role uses this variable for each host in
the borg-backup group to initalise users.
Hosts can place into /etc/borg-streams which should be a
script that outputs to stdout data to be fed into a backup archive on
each run. This will be saved to an archive with the name of the file.
This is useful for raw database dumps which allow borg to
deduplicate as much as possible.
Role Variables
The username to connect to the backup server. If this is left undefined, it will be automatically set to
borg-$(hostname)
