unrelated to your problem, but this is pointless. The global config is
included anyway. You can use 'do ...' to include a config for a group of hosts
(e.g. "do '/etc/backuppc/all_my_servers.pl';"), but for the global config this
is meaningless.

This is wrong, as you see in the error message. The RsyncClientPath is
/usr/bin/rsync. The sudo comes into the game in RsyncClientCmd.
As a side note, the '-n' option to sudo is sort of pointless. You need to
configure sudo correctly. '-n' just makes it fail in a perhaps more obvious
way. Adding the '-n' is sort of saying "I'm expressly preparing for this to be
wrong". Use it for debugging, but then remove it (well, my opinion).

$Conf{RsyncClientCmd} = '/usr/bin/sudo $rsyncPath $argList';

Note that I removed the '+'. sudo does *not* add an additional shell level, so
you don't want extra quoting.

Same here. Add 'sudo', remove '+'.

If you're excluding the directory 'archive', you're implicitly excluding
everything beneath it. Do you *want* the directory itself (without content)?
Using '**/archive/' should otherwise be equivalent (and if you *do* want the
directory itself, '**/archive/*' should be sufficient).

You likely don't have a command 'sudo -n /usr/bin/rsync' in /usr/bin, or
rather, you probably don't have a directory 'sudo -n ' in /usr/bin, which
in turn contains 'rsync' within subdirectories 'usr/bin'.

The incorrect escaping is due to the fact that you specified RsyncClientPath
incorrectly above.

Apart from that, everything looks good.

Hope that helps.
