If you have your database(s) locally (on the same
computer or in a local network) then you can choose this method
of backup. This is the window for Local Backup method.
It is the window for Remote Backup method. If you
have your database(s) remotely (on the internet, etc) then you
can choose this method of backup. For this you need to place a
server-side script (with the program installation included) on
to your server in appropriate folder and fill in appropriate fields
in 'Remote Backup Window'.
The Local Backup method: Here you need to choose from
the list of all existing on the MySQL-server databases those ones,
from which it is necessary to make backup copies (mark them with ticks).
