How to design a centralized cross-platform BACKUP solution ?

["J. Bakshi" <bakshi12@gmail.com>]

Hello list,

I like to implement a debian server with plenty of HDD space to work as a centralized net backup
server. The idea is both Linux and windows users can keep their backup at this server ( may be just folders;
or a complete partition or two); can browse their backups through web interface, can easily restore 
and the main thing minimal client configuration.

I have already "apt-cache search" in debian and I have found close to my scenario is backuppc.
Though amanda is also there but I don't know how much it comes closer to my requirement.

Hence I am in a phase to just listen to you; about your experience and implementation.
Waiting to hear you... 

Thanks
