[Samba] a matter with winbackup

[enrico]

we tried to use samba to serve a windows network. In that network we use
iomega backup to copy folders from any pc to the server. 

All the network works well, but iomega backup can't create directoryes
and don't works. 

We tried with winbackup, but that software has a much of matters with
winxp. 

Someone knows hot to solve this problem ?
There is a scheduled-backup software for windows that works well on a
linux server ? 

thanks
