What do you mean by "recons" or is that a typo?

The answer is that the "*" operator is file globbing (like 'ls') and
not the general regex operator "*" -- i.e., it doesn't match "/". This
is by design since file globbing is much faster (and in some ways
safer) than doing a 'find' on the directory tree.

I suggest you first manually do a find on a sample backup tree to find
where the iso files are and then construct the path with or without
(globbing) to delete them.

You could also do something like this to do it all at once.
./backuppc_delete.pl -t -c  -h ns -n - `(cd /var/lib/BackupPC/pc/ns ; find . -name "*.iso"| sed -ne "s#./[^/]\+/##p")`

where you first cd to your pc tree and then find *.iso files and then
use sed to remove the leading backup number directory.

Note: 1. Keep the '-t' there to test this works and that it is not
 	  	 about to remove things you don't want
 	  2. Since find returns files with mangling, I removed the '-m'
 	  	 flag.
	  3. Don't use the -r since you are not removing directories (presumably)
	  4. The -s flag is not necessary since the find is returning the
 	  	 share part of the path.
