CiviCRM backups are filling up the disk

Currently, about 80% of the root volume on crm-int-01 is occupied by MySQL backups.

Creating new backups and cleaning up old ones is triggered by /etc/cron.d/local-backup-mysql and the scripts referenced therein, all of which is custom shell scripts unmanaged by Puppet.

We should review this system and check why the backups are accumulating. We should also possibly look into replacing this backup system with something less bespoke.
