This sounds like an extremely simple situation, and 40GB of data is
nothing. In your place I'd designate a single machine, possibly an
additional one dedicated for the purpose, to be a server; set up a disk
SD on that machine using the NAS as storage; put a client on each of the
machines to be backed up; and just figure out a backup schedule that
works for you. There's nothing at all complex about your configuration.
If I were setting up a schedule for your situation, I'd create separate
disk pools for full and incremental backups, I'd divide the clients into
five sets of ten, and create a schedule for each group, staggered such
that ten clients get full backups each weeknight, just to spread out the
traffic instead of having a big spike of network load once a week.
Remember that you will need to increase the maximum job concurrency on
your both your Director AND your SD to at least the number of clients
plus a reasonable safety margin. There is no cost to setting the
concurrency "too high". In your case, with 50 clients, 75 would be a
good safe setting.
Let us know if you run into any problems, but this sounds like a very
straightforward installation.
