RKE recurring snap


I am new to rancher.

Few questions -

  1. How do I set RKE recurring snapshot to occour every 10 minutes and retain snaps worth 4 hours. I did something like below in cluster.yaml and its not working. Testing things on single node RKE cluster.

           interval_hours: 0.10
           retention: 4

Its actually showing -

time=“2020-06-09T12:39:06Z” level=info msg=“Initializing Rolling Backups” creation=12h0m0s retention=48h0m0s

  1. Also, if I kill some of containers running RKE manually, shoudn’t those be created automatically? I could only get those back after I ran rke up again.
