@shubham-pampattiwar Two more following up comments from me and @blackpiglet, see if you could address it. Basically, we suggest to avoid generating a dynamic client inside the helper, but get it from the backup as an input parameter and then call the existing function in util/pvc_pv.go.

@shubham-pampattiwar We also see the code coverage has dropped by 0.24% due to this PR, could you help to add some more test case?

@Lyndon-Li @blackpiglet Addressed PR feedback and added tests. PTAL, Thanks !
