> Components: server
> Affects Versions: 3.6.0

> Basic systems to backup ZooKeeper data will maintain snapshot files of the
> data tree. In order to understand the health of these systems, they need a
> way to determine how in or out of date their files are to the current state
> in the ensemble.
> Add an admin command that exposes the zxid and timestamp of the last
> saved/restored snapshot of the server. This will let such a backup system
> know when it can update and when it is stale.
