Who can help me to create a backup strategy that will copy the
backend.mdb into separate folders representing either the time, or
just folders that are sequentially numbered.
I need this for rollback purposes.
What follows is an ugly little vscript that I run on the task manager
to backup. It zips up the current file and uploads to the server. I
think it keeps five versions. It won't backup if there is a lock
file(ldb). It also compacts the database and has rudimentary logging.
Do with it what you will. Enjoy!
