Hello world,

our company is planning to move to Bacula. Preliminary tests are
looking fine, but we really don't know how to deal with a few things.

As for hardware, we got a 24TB raid and access to a working tape
library with several drives.

1. Keeping configuration sane: With more than 120 servers, we need to
find a way to keep the configuration files readable. Our servers all
follow some naming scheme, for example, we got "appserver01" through
"appserver08" or "webcache01" through "webcache04". We think we should
split client configurations for each server group, so the file
"clientdefs/appserver.conf" would define all appserver0X clients.
Furthermore, most of those servers will need a default job performed
(/etc, /root, /opt and so on). While it's easy to reuse a "JobDefs"
stanza to actually define all those jobs, isn't there any way to
"group" those servers? Do we really have to define more than 120 jobs,
one for each server?

2. Backup availability: One plan would be to use a large part of the
24TB available as a FilePool (or several). Each job would then write
it's data to that pool. A Copy job could copy the data to tape later
on - with the advantage that restores of recent data would be quite
fast since they would still be sitting on disk. Before running the
backup the next day, we would simply recycle those file volumes. Is
that a reasonable strategy?

Any hints on this would be very appreciated.
