Yes, we'd like an estimate per GB, or 100 GB or 1 TB. Whichever units
make sense. The alternative we've been considering is buying a new server.

A copy of our current bacula director config has been sent to Lance. In
some cases (e.g. Apache) we actually want to keep some logs. We are
still undergoing some refinement to make the whole thing more efficient.
I assume you can take care of the keys, since you have access to all the

Generally no, we hope to never have a need for such a restore and in
such an event we'd likely be filing a ticket with you anyways because
something went wrong with the hardware or VMs. Though access to extract
some files from the backups would be nice long term.
