Could also say how long a backup is going to take roughly. Me as an operator
would be afraid to run a backup because I'd think the command could run for
ever on my 100 node cluster. Reading later in the manual, it seems that it
could start and return immediately and then I check in on status. Would be good
to surface some of that up here at start of doc. to allay the fears of the poor
operator.

No, we can not estimate duration of an operation yet. It depends on : # of YARN
containers allocated to an operation, available resources CPU, IO memory to a
container, overall system - wide load etc, available inter-cluster bandwidth.
Backup and restore are both blocking operation, because are client driven. So,
they return only when operation finishes successfully or fail.
