Issue Number: ref #52534
Problem Summary:
Due to tikv/tikv#17168, the current tikv does not support backup with subranges very well.
So we need a version checker in case of use store based backup running on old version of tikv.(There is no correctness issue, but the performance may not work as expected.)
What changed and how does it work?
