If you have another machine that isn't busy at night, the simple 
solution is to just run a completely separate instance of backuppc and 
split the clients up. One of the nice things about free software is that 
it doesn't cost any more to run more copies.

You can use RAID0 to combine disks but keep in mind that it (or LVM) 
makes it twice as likely that you will lose data since a single disk 
failure will lose data from both.  A safer alternative would be to use a 
pair of 750gig or 1TB drives which aren't horribly expensive these days 
in a RAID1 configuration.  With software raid you can recover from 1 
disk even if you move it to a different machine/controller.

That can work, but unless your target machines are unusual, I would 
recommend keeping at least 2 fulls.  My most common reason to recover 
something is that a user deleted or modified some files and didn't 
realize until a few days later that they needed the old ones back.  With 
the scheme you propose there will be a day where you only have the 
previous night's run.
