Hi, Ted
I'll answer some in the middle of your mail, but there's some things I would
like to see first:
1- With backuppc you may say I want to backup everything from that client
("/" or "C:\ and D:\, etc...") or instead say I want to backup just this,
and this, but not that- the concept is "shares".
So you may have two (or more) backuppc servers if that helps your questions.
One backup this, the other backs up that and the clients.
backuppc needs very little maintenance, so I think that's an option.
2- backuppc is very little demanding of the machine. Any machine with apache
will do it. That besides the pool thing :)
3- About pool. It can be on the server disk(s), RAID1 would be a good idea,
or any kind of external mounted partition. A NFS share, for example. But
you'll be limited by the speed and bandwidth of your LAN. backups will
travel twice, I think.
4- I understood you want to archive to DVD and free space.
Archive is somehow direct. To delete older backups (not automaticaly, not by
schedule, that is) you may use a script that was shared in this mailing list
(I can send it to you)

Answered, I think. I'll move the server and pool to another machine.

I have some experience on DVD failure, regret to say.
Archive, AFAIK, is a compressed file, store it on DVD or move it to another
media (or both)
Delete the backups after with a script, or wait for the automatic delete
after you delete the files from disk.

Just don't ghost the pool, I guess - make pool a partition, so you may
exclude it from ghost.

Hope haven't said anything stupid. Anyone, please correct me.
Didn't answer all your questions, probably, but hope will get to it :)
Finnaly, backuppc may not be the perfect tool to backup a bunch of web pages
from diferent sites.
But it will do the job.
