If you install a packaged version, the configuration step that allows
you to specify alternate locations has already been done and you can't
change it.

You might be OK if you undo your config change and
ln -s /mnt/usb/BackupPC /var/lib/BackupPC.

None, but the target must be in the expected place and on the same
filesytem as the pc dirs.

No, every file stored under pc gets a hardlink in pool or cpool
(depending on compression) that is based on a hash of it's content, so
all matching files (with some tests for hash collisions) end up as links
to one instance.
