Hello,
and welcome to the mailing list!
I hope we can help you solve any issues you encounter with running
Bacula, and of course I also hope that you'll help others as well!

I assume this works as you want it and you've go some experience with
Bacula by now.

Sure, see below. And keep in mind that there is also commercial
support available - if you want to move some of the design and
implementation work to someone specialized on this sort of tasks,
there are companies available to assist you (Bacula Systems SA and
it's partners would be a good choice, of course ;-)

Here, the services will be the major task. VSS probably covers some of
them, but others - Oracle of course - will need some glue scripting.

Remote as in "connected by WAN/VPN"... ok.

Nicely sized network. You'll probably have some work to do with
firewalls and VPN gateways, but that's probably no news to you.

Reasonable, but it might be simpler if you use less pools. A pool is
most useful to organize backups into volumes with different retention
settings and media types - finding the right volumes to restore a
certain client from is handled by Bacula itself quite reasonably.
If you need to assign responsibilites for groups of clients to
different backup operators or admins, reflecting that responsibility
in the pools is, of course, reasonable.

So creating and maintaining all those filesets will be a good part of
your day-to-day workload with Bacula. I suggest you start
experimenting with include files and auto-generated configuration soon.

Ok, that's reasonable. I assume you want volumes to be labeled
automatically.

That in itself would not be a major problem, provided you've got
enough storage daemons to run many jobs in parallel.

I suggest you start thinking the way Bacula works, as it makes life
easier in the long run: "at which time the volumes *can* be
overwritten". If you want to force Bacula to overwrite volumes you're
starting a long struggle.

Ok.
Don't forget to assign unique media types to all the SD's (or rather,
storage devices) you use.

Probably better and more efficient to use a copy job to copy the
latest full backup to tape. Saves bandwidth, and it doesn't break the
relationship between full level backups and incremental / differential
ones.

The schedules don't have anything to do with the pools.
How you use pools is mostly a high-level decision, i.e. you could use
one pool only per storage device, or one pool per client. Quite often,
this is a matter of taste - but one pool per department sounds like a
reasonable compromise.

I guess that, for your network size plus some growth over time, one
central DIR should well be able to handle it. You'll need a decently
performing server and a well-performing catalog database, of course.
And reliable WAN connections...

Yup, that's what I'd recommend. Keep in mind that the traffic can be
more than you expect, due to all the metadata that gets sent to the
catalog!

Not personally, no. I do manage or personally know some Bacula
installations that are similar in number of clients, but those
typically have all the backed up machines in one data center. I think
the main issue you'll see is the WAN performance and stability. VPN
tunnels can make stability much less of an issue, and ssh tunnels
allow you to pass firewalls quite easily if no VPN or dedicated WAN
link is available - you might want to check the list archives, as
during the last few weeks, ssh tunneling has been discussed a bit.

You're welcome - your setup sounds like a nice and interesting
project! If you want commercial support don't hesitate to ask me! ;-)
(Or ask Bacula Systems - though we don't have a pertner in the US yet,
we might be able to help you anyway.)
