Some questions on Storage Unit groups.

 

The purpose is to have a couple of Storage Units grouped so that backups will go from 1 Media Server to another when the first Media Server is down or busy AND the job stays queued when all Servers are busy.


There are several options:

Prioritize.  Which is unacceptable as this will fail the job if no non-busy server is found.  Or can this be changed?)

Failover.  When a server is full the job will be queued (possibly leaving other Media Servers idle = Not good either).

Round Robin.  Same as first: Job will fail when no Media Serve is found.

Load Balance.  The explanation in the guides are not clear about this.  What happens when all Media Servers are busy (full) ?  Does the job stay queued (and for which STU) or does it fail ?  Requires Flexible Disk option license when using DSU.

 

Or are there other options that I did not think of to accomplish this ?
