The new year started off poorly for my backups, and it is all my fault. Each of my remote servers is backed up utilizing Bacula’s TLS (Transport Layer Security) features. This requires an X.509 certificate which I obtain via CACert. These certificates have expired:

My solution is simple: renew the certificates, install them, and [perhaps] restart the bacula-fd in question.

The problem arose simply because I forgot to renew the certificates, despite reminder emails from CACert. The update was easy, but time consuming. I had to update three hosts.

Happy New Year.
