[Samba] Feasibility question: get samba to back-up every version of a file

You can accomplish this with a VFS module.

As I remember there was supposed to be a SoC project doing this but I  
don't know what happened.

Using VFS you can trap all kinds of file operations (look at the  
recycle bin module to see how they move a file on delete instead of  
deleting it)

You would need knowledge in C/C++ but you can probably figure a lot  
out by looking at the Audit module.

If you would make one please send me a copy ;)
