Wouldn't that be great! I was looking very briefly at doing this under
Debian, I guess the idea would be that you take the installer and add
some more stuff to it (bacula-fd, -sd, and -dir), and then remove most
of the stuff that does the actual installation.

As I mentioned in another email, the Backup Exec IDR does almost exactly
that - it creates a CD derived from your installation media but with
some hooks in place to call the installer after the base operating
system is installed, which has the advantage that the base operating
system is configured for the current hardware and not the hardware of
the system that was originally backed up, which may be different.

My ultimate wish is that you wouldn't have to do any real preparation
(burning CD's etc) for a disaster other than taking your tapes off site
nightly and making sure that your system state info is on that tape. The
recovery procedure would first extract the system state from the tape,
apply it, then restore everything. There would be a few levels of
automation ranging from "everything is on this single tape, the client
name is xxx, restore it", to "I want to set up my partitions a little
differently this time, and I want to restore the last full backup which
was two weeks ago and then all the differentials since then except for
last night when the rootkit was installed".

The restoring system state from tape idea should be pretty simple if
your director, catalogs, and sd are still running as you could identify
it and restore it pretty simply. In fact, if you defined a job that
restores the state and then runs the apply script as a 'run after job',
you could drive it all from the director as long as nothing went wrong.
(or do the scripts not work on a restore?)

Restoring the system state from tape when your entire network is in
pieces is obviously a bit harder, especially if you aren't doing a
simple one tape = one nights backup model. Our client base is mostly
small businesses with <100 employees who use Symantec Backup Exec or
NTbackup. Most of the time the backup tape is changed blindly each
morning. My philosophy for such businesses is that if everything can't
fit on a single tape, you need a bigger storage solution. Two tapes or
differentials get too complicated, and when things get complicated they
get done badly. Obviously everything changes for larger organisations or
organisations that just have more data than can be physically spooled to
tape in a single night.
