I had created a separate device in SD for every job I needed to run 
independently, because I didn't want the very small jobs (eg. backing up 
configurations) to be waiting for big jobs (eg. backing up gigabytes of users' 
data over WAN). The rule was that I had at least one device per client (that 
was actually pointed to the same subfolder (meant for the client) on the same 
partition), so that clients wouldn't bother each other.

DIR: 10
SD: 20 (yeah, it should've been at least the same as DIR's, but it didn't 
matter much)
clients: 10
storages: 6 (in order to be able to run multiple instances of one job - that 
was necessary to cancel duplicate jobs with a script)
jobs: 10 (actually 2 would be enough, I think)

I had total of 35 devices previously. I'm backing up to disk, so the fact that 
one device can run only 1 job is a real limitation in my case.

Number of storages/devices I have currently - 3 clients have really big jobs 
so I want them to be able to run independently of other clients, other clients 
are backed up to the same storage/device.
