> {quote}
> Specifically, the client does a checkAndPut to specifics coordinates in the
> backup table and throws an exception when that fails. Remember that backups
> are client driven (per some design review from a long time ago), so queuing
> is tough to reason about (we have no "centralized" execution system to use).
> At a glance, it seems pretty straightforward to add some retry/backoff
> semantics to BackupSystemTable#startBackupExclusiveOperation().
> {quote}
> While we are in a state in which backup operations cannot be executed in
> parallel, it would be nice to provide some retry logic + configuration. This
> would alleviate users from having to build this themselves.
