Nobumi,

If you want a mirror forget about backup and perl, and go for rsync.  
Just say : do shell script "rsync -a --delete 'the source' 'the  
dest'", it's killer. Many options, it's a pleasure.

FWIW, as you know we (quomodo.com) use intensively the features of  
Smile and Satimage osax, but we are dropping "backup".
