I am in a similar situation and it works out fine. I am a windows
programmer who generates 50K lines of code per year. I am the network
and system administrator for a department of 20 users (and over 15TB
of data) with around 70 machines with mostly windows
desktops/laptops/workstatiosn and linux servers. I build all of the
computers for the network and install all of the software. We have
over 10TB of linux software raid5 and 6 that I have setup and we are
in the process of adding 5TB to 10TB more. I design the everything to
be inexpensive and yet we still have good performance. For us a 3TB
raid 6 server (dual core 4 or 8GB of memory) costs us less than $2000
US for the entire system. The network is complicated by the fact that
we need 2 networks. One for the company/internet the other to archive
gigabit to every single machine. And this is on the cheap also. For
less than $3000 US we have 70 computers connected to 3 X 48 port
gigabit netgear managed gigabit layer 2 switches. The company said
this would cost over 1 hundred thousand if they used the mandated
cisco equipment..
Anyways (my point here) the time I spend administering bacula is
probably less than 10 minutes per week so its not like this will take
you a lot of effort.

I am, well at least the mail server that sends out system messages
when bacula needs a tape or nagios detects a problem with one of the
machines.

I would not do that since it is way too much work. Have at least 3
tapes and make the recycle period much longer (a month or so). That
way you can do Fulls monthly with incrementals every day and
differentials weekly. I do this for my user (public and private
folder) backups and a DLT-IV drive with a 10 tape rotation. I have
bacula email me of the tape change which probably happens 1 time every
3 weeks and then two times for when the Fulls are run.
