Not necessarily, no.  You certainly don't need to save bootstrap files;
they are generated at restore time.  Having the catalog data is not
necessary either, as it can be reloaded into the database via bscan; but
bscan can take a while.  You could include a catalog dump with each
dataset, but there is no specific provision in Bacula to take an
external catalog dump and cleanly merge it into the running catalog.
I've never tried doing so manually myself, and could not vouch for the
safety of such a process.  If you were going to do that, the SAFE way
would be to extract the catalog dump to a new location, stop Bacula,
restart it pointing at the alternate catalog, then perform your restore.
 Whether this is feasible is going to obviously be hihgly dependent upon
how busy your Bacula installation is.

You COULD, of course, hypothetically speaking, run a second Director
specifically to do such restores, starting it up only when needed.
