LocalPV supports ZFS Snapshots.

MongoDB is shitsoftware anyway.

I use k8s in a very small setup (3 worker nodes, 3 ctrl planes) in my startup. But i'm working professionally with k8s for 6 years.

My setup is relative big but also relative simple and most of it is also IaC. I don't need to backup my setup and i don't need to document how i setup everything.

I have blue/green deployment, multiply enviorrnments (dev, test, prod) configured 100% equal, a good monitoring stack + tracing, s3 replication, postgresql ha and offside backup.

i can shut down a node and nothing happens.

But you know, if k8s doesn't fit your time and experience and benefit estimation, don't use it.

The upfront cost of k8s is bigger though.
