Looks nice, but what's that for?

As a pod, it will always be there consuming resources, which is not great for dev env, for example, but ok for other envs.

This pod will be checking the backup folder on this pvc? What else do you think will be good to add as commands for this specific pod?

[DerekRoberts]

@paulushcgcj It's tied to a script and won't be long lived. Just for checking PVC backups right now.

@paulushcgcj It does give me more ideas, like scripting backup verification! Unfortunately that's out of scope for the moment.
