Backup module ?

[Michael - acm3.c. <ml...@ac...>]

Hi,
 
I have a question on th backup module...  
 
I was trying to set up a backup, of a specific directory, going to a
specific location.  I could not get it to work...
 
Basically, what I want to do, is I have several web sites on my box, and
I would like to backup each one individually daily, with the backup each
night, over writing the existing backup.  (Possibly using .tar.gz
format)
 
This way, I just create a linked url, and download when I want.
 
Not sure if that module allows this, or not.
 
Any ideas?  Or scripts that do this already I can port into the system..
 
Thanks
 
Michael
