Used to encrypt Database Master Keys, Linked Server passwords and Credentials it is generated at first SQL Server startup. As illustrated in Figure 1, backup files of databases with TDE enabled are encrypted using a key hierarchy that includes the service master key of the SQL. There is one per SQL Server instance, it is a symmetric key, and it is stored in the master database. TO DISK = 'E:\GKKeys\smGKFULLEncrtypted. Service Master Key: At the top of the key hierarchy is the Service Master Key. ,ENCRYPTION BY PASSWORD = 'smGK_BackupCertificate_BACKUP_Password'Ĭreating the backup: BACKUP DATABASE smGK TO FILE = 'E:\GKKeys\SMGK_BACKUP_CERTIFICATE.cer'įILE = 'E:\GKKeys\SMGK_BACKUP_CERTIFICATE_PRIVATE_KEY.key' I am doing the following steps:Ĭreate and backup database master key in the master database which is going to be used to encrypt our certificates USE MASTER ĮNCRYPTION BY PASSWORD = 'MasterKey_Password' ĮNCRYPTION BY PASSWORD = 'MasterKey_BACKUP_Password' Ĭreate and back up the certificate that is going to be used for encryption: USE MASTER On the new SQL server, re-create the master encryption key by running the following T-SQL statements. The SMK is created during installation and stored in the master database. Restore the most recent database backup to the new server. A copy of the MEK is encrypted using the Service Master Key (SMK) and a copy is stored in the master database. I want to create an encrypted backup on one of the databases and then restore it on the second instance. The Master Encryption Key (MEK) is protected with a mandatory password and 3DES. I have two SQL Server instances on same machine.
