I would like to force a backup of user's local data at Windows startup. Once
logged on the network I would like to verify the date of the last backup file
within their Users\username\backup directory and if this file is older than
four weeks force a complete backup that cannot be stopped by the user.
Currently they have a batch file using winzip to manually backup their data
but of course certain laptop users tend to disregard this option.

Our current login script is visual basic.
