Single play not possible with remote system

[carygravel]

With a remote system, it is not possible to run the first play without error.

• If you run rsnapshot-remote-host first, it fails because the user has not yet been created by rsnapshot-backup-host.
• If you run rsnapshot-backup-host first, it fails because the user has not yet been created by rsnapshot-remote-host.

The best you can do is run rsnapshot-backup-host, which creates the user on the host, but errors later fetching the remote user key, then rsnapshot-remote-host, which is then successful, and finally rsnapshot-backup-host again, which is then successful.

However, my play for rsnapshot-remote-host is the trivial:

- hosts: REMOTEHOST
  become: true
  roles:
     - role: yannik.rsnapshot-remote-host
       rsnapshot_backup_host: LOCALHOST

The above could have been created automatically, given the backup_host variable(s) has all the info needed.

Could the two roles not be combined, then it could all be carried out with one play, and without error?

Interesting question. While I am actively using both roles, I do not set new backup servers very often (mostly new nodes to be backed) up, so I don't think remember experiencing an issue with this.

The foolproof setup method is this:

1. Run rsnapshot-backup-host on the host pulling the backups, with no rsnapshot_backups configured

then, for each host you want to pull backups from (or all at once)

1. configure relevant rsnapshot_backups
2. Run rsnapshot-remote-host on the host you want to pull the backup from
3. Run rsnapshot-backup-host on the host pulling the backups

However, this rather complicated procedure is not really required (I'm not using it either). Instead, it should be possible to simply run rsnapshot-backup-host (with rsnapshot_backups configured) and then run rsnapshot-remote-host. In this case, you will see an error on the Check that ssh to hosts works task during the rsnapshot-backup-host run, but that is only of informative nature (totally makes sense since you haven't configured the host you are pulling backups frmo yet), and does not lead to failure.
