MDB file

Hi

I have a program that use mdb file to store data.

What I will do with this is to backup the file

I know how to do that, but the question is
how to make backup of the file so I can
go back and restore the file from 10 Days ago.

I mean how to number the file we say

like this phone.mdb
phone.mdb1
and so on
