How does Transparent Database Encryption protect backups?
Databases on backup media are as much at risk, if not even more so, than databases on the server. Of course you use a backup password, but anyone that needs to perform a backup or a restore needs to know the password. In fact, it is probably taped to the backup console! Encryptionizer can automatically encrypt a backup, as it is being created. This allows an additional layer of encryption, for which the backup operator does not need to know the key. What’s more, if someone takes the backup media and tries to restore your database to a different machine, or even instance on the same machine, it will appear as an unreadable backup.
