 ### Manual Backups
 Manual Backups can be performed by entering the container and typing `backup-now`
 
+- Recently there was a request to have the container work with Kukbernetes cron scheduling. This can theoretically be accomplished by setting the container `MODE=MANUAL` and then setting `MANUAL_RUN_FOREVER=FALSE` - You would also want to disable a few features from the upstream base images specifically `CONTAINER_ENABLE_SCHEDULING` and `CONTAINER_ENABLE_MONITORING`. This should allow the container to start, execute a backup by executing and then exit cleanly. An alternative way to running the script is to execute `/etc/services.available/10-db-backup/run`.
+
 ### Restoring Databases
 Entering in the container and executing `restore` will execute a menu based script to restore your backups.
