How does whole 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 to hard disk, or even directly to tape, as it is being created. This allows an additional layer of encryption, which the backup operator does not need to know the key for. What’s more, if someone takes the backup media and tries to restore your database to a different installation of SQL Server, it will appear as an unreadable backup.
