As Dan pointed out - what the underlying OS needs. I had Bacula
running on an intel Pentium with, IIRC, 233 MHz and 128 MB RAM
(catalog DB was on another machine).

I've got Bacula running on an AMD Athlon 500 with 512 MB RAM.

I've also got several instances of Bacula running in Virtual Machines
with less than 512 MB RAM.

I'm pretty sure that, in theory, you could run a full Bacula on a
really minimal system, say 486-class, with 32 MB RAM and no local
disks at all, but I won't try this now :-)

A high percentage of what your hardware can deliver - I've seen
reports of Bacula saturating multiple LTO-3 drives, or two LTO-4 on
standard x86 hardware. If you look at what is possible with "real"
server hardware, and how well Bacula can scale if everything is
configured and tweaked, I don't think there is any built-in limitation
to Bacula's throughput. If you provide a really big Server with many
fast local disks, many fast FC connections, and a really fast SAN
storage, I'll gladly help you tweaking your setup :-)

Henrik gave some numbers - I believe he doesn't need any really
special hardware to get those numbers.

Will be limited by the available storage capacity only, so, in theory,
close to infinity... for practical reasons, you'll want some
information in the catalog, so I just invent a number and say "up to
10 Exabyte". Anyone claiming more please show me :-)

;-)

If we knew what you wanted to show or prove with your paper that might
even be possible.

Cheers,

Arno

If the OS and database are running, then Bacula should run too.

That is completely outside of Bacula's control. It is very much
dependent upon your hardware and tuning of your OS and database. Put it
on fast hardware, it'll fly. It is completely limited by outside
influences.

No pre-set limits.

Are we doing your research for you? :)

I started with 1.6 Ghz Celeron, 512MB, VXA-2 tape drive.
All the daemons there, as well as the MySQL catalog.

File server was in the same system. I think it was Bacula 1.38,
or maybe even 1.36.
The same hw served until 2.x
Then I got a VXA-320 autoloader.
Soon thereafter I upgraded to 2.8 GHz P4, 1 GB.

I strongly believe that even today's newest Bacula would run in that
beginner's system above. Of course, the performance wouldn't be
top-grade, but it's never top-grade with low-end hw.
