I have a Windows 7 computer which currently has a large working Microsoft Access 2007 database on it containing some tables with confidential data. I would like to securely delete/remove the tables with the confidential data. I'm looking for a good protocol on how to do this.
Does all the data live in the *.mdb file?
Should I be concerned about temporary back-ups made by Access while the DB is open?
I would also like to kill the backups managed by Windows 7 back-up. Is there a good way to remove sensitive data from a Windows backup?
