Greetings!

I have a question, but actually in three parts.

We would like to set up permanent off-site archives from multiple
systems/policies executed from the command line, but only a few of the
policies would actually fill a tape to a capacity worth actually
removing it from on-site. Most of the archives are only a few gig, not
even coming close to the capacity of the LTO-1 tapes. I've checked the
NB SysAdmin guide, but bparchive does not seem to have a flag for this.
It would be a shame, not to mention expensive, to send tapes out forever
with empty space. So, with that in mind....

1) Is there a way to specify a particular media to back up to? Can I
pick a tape to media archives to?

2) If so, is there a way to specify multiple policies on a single
archive media? 'yes' to #1 would really answer that.

3) Is there a way to ensure that a single archive will be written to a
single tape, assuming the capacity of the media allows that (i.e., not
starting the archive on a media that already has another archive or
possibly even normal backup on it? Again, 'yes' above on #1 would really
answer that, as well.

I considered a creating a policy-zilla where all my archives were in one
big fat policy, but a) there are a multitude of different
files/directories between the systems to archive, and b) it's just not
sexy. Plus, I'm not sure it guarantees my archives are still on one
tape, even without the multiple streams checked.

Thanks to all for any info (and for previous help on other topics!).
