Should we add the setup related func to a setup func?

I think if we are not achieving optimisation or resource saving thne its ok to be as it is.

where are checking for the below steps-

get operation on the bucket gets the data that was stored before shutdown

delete operation on the bucket can delete the data that was stored before shutdown

put and list operations work correctly

S3 operations on NSFS bucket on files is not implemented yet.
