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.
