Database Backup Encryption & Recovery

  • What happens if a server "Dies" and a new server needs to be rebuilt, using encrypted backups ?

    If I create a master key

    CREATE MASTER KEY ENCRYPTION BY PASSWORD = '<master key password>'

    Then create a certificate

    CREATE CERTIFICATE MyTestDBBackupEncryptCert  WITH SUBJECT = 'MyTestDB Backup Encryption Certificate'

    Then backup my database  WITH ENCRYPTION (ALGORITHM = AES_256, SERVER CERTIFICATE = MyTestDBBackupEncryptCert )

    So all my backups are encrypted, what is needed to ensure I can restore them to a new server in the event of disaster to the original server ?

    Does the certificate need to be backed up and stored "off site" , then restored on the new server ?

  • You need to backup the certificate. Microsoft lays it out right here.
