It should have stopped doing backups when you had used 95% of the space
and sent you email as soon as some machine had gone a few days without
backups unless you changed the defaults. There was a bug in earlier
versions where the email didn't get sent if backups were skipped because
the space was low. I'm not sure when this was fixed.

If the backuppc archive isn't on it's own partition, you might have some
large logfiles (or spooled mail files) taking space.

That's correct - unless your cpool directory is on a different partition
than the pc directory and all the attempts to link files are failing.

Yes, but large files that change slightly can be a problem, like mail
files in unix mbox format (all messages in one file), database files, or
virtual machine images. You'll get a complete separate copy if a single
byte changes.

The 'new files' in your listing didn't look like they should be a
problem. I'd look for anything else that might be using space first
("du -s *" in /var, for example).
