Why is it important to make a backup copy?
Your database may be damaged or deleted due to any kind of hardware or software error, as well as due to a virus infection. In this case our data can be reached only from a previously saved database. That is why it is very important to make a backup copy as often as possible.
It is essential to know that you cannot open your database by an older version of the program if the database itself was created or edited by a later version.
