Ho il requisito di eseguire il mirroring di alcuni database e di utilizzare anche la crittografia dei dati trasparente (TDE) su di essi poiché i nostri dati devono essere crittografati mentre "a riposo".
Ho installato TDE sia sul principale che sul mirror. Il problema che ho entra in gioco quando sto configurando il mirroring dei due database. Dal momento che sto usando TDE non conosco un modo per impostare il mirroring tramite l'interfaccia grafica, quindi sono costretto a usare t-sql per fare il lavoro.
Di seguito è riportato il codice che ho usato sul server con mirroring
--Restore the full backup to the mirrored mdf and ldf
OPEN MASTER KEY DECRYPTION BY PASSWORD = '1Password'
RESTORE DATABASE TDE
FROM disk = '\\SERVERNAME\SQL_Stuff\Backup\TDE_FULL.bak'
WITH NORECOVERY,
REPLACE,
MOVE 'TDE' TO 'E:\TDE.mdf',
REPLACE,
MOVE 'TDE_log' TO 'G:\TDE.ldf'
CLOSE MASTER KEY
GO
--Restore the log backup to the mirrored db
OPEN MASTER KEY DECRYPTION BY PASSWORD = '1Password'
RESTORE LOG TDE
FROM DISK = '\\SERVERNAME\SQL_Stuff\Backup\TDE_LOG.trn'
WITH NORECOVERY;
CLOSE MASTER KEY
GO
--Drop/Create Mirroring endpoint on mirror
--DROP ENDPOINT TDE
CREATE ENDPOINT TDE
STATE = STARTED
AS TCP ( LISTENER_PORT = 7025 )
FOR DATABASE_MIRRORING (
ROLE = PARTNER
);
GO
--Check the endpoints for the mirror
USE MASTER
SELECT * FROM sys.database_mirroring_endpoints
GO
--Set the principal on the mirrored db
OPEN MASTER KEY DECRYPTION BY PASSWORD = '1Password'
ALTER DATABASE TDE SET PARTNER = 'TCP://PRINCIPAL.DOMAIN.local:7022'
GO
CLOSE MASTER KEY
GO
Di seguito è riportato il codice che utilizzo sul server principale.
----------------------Mirroring Section----------------------------------
--Full Backup of Principal
USE TDE
GO
BACKUP DATABASE TDE
TO DISK = '\\SERVERNAME\SQL_Stuff\Backup\TDE_FULL.bak'
WITH COMPRESSION,
NAME = 'Full Backup of TDE';
GO
---Log Backup of Principal
USE TDE
GO
BACKUP LOG TDE
TO DISK = '\\SERVERNAME\SQL_Stuff\Backup\TDE_LOG.trn'
WITH COMPRESSION,
NAME = 'Log backup of TDE'
GO
--Drop/Create Mirroring endpoint on principal
--DROP ENDPOINT TDE
CREATE ENDPOINT TDE
STATE = STARTED
AS TCP ( LISTENER_PORT = 7022 )
FOR DATABASE_MIRRORING (
ROLE = PARTNER
);
GO
--Check the endpoints for the princple
USE master
select * from sys.database_mirroring_endpoints
GO
--Set the mirror db on the principal db
OPEN MASTER KEY DECRYPTION BY PASSWORD = '1Password'
ALTER DATABASE TDE SET PARTNER = 'TCP://MIRROR.DOMAIN.local:7025'
CLOSE MASTER KEY
GO
Ho impostato prima l'endpoint di mirroring, quindi l'endpoint principale. Emetto quindi ALTER DATABASE
sul mirror, quindi sul principal, dove ottengo l'errore risultante:
Msg 1416, Level 16, State 31, Line 2
Database "TDE" is not configured for database mirroring.
Sono in perdita su cosa fare al riguardo. Il mirror è nello stato di "ripristino", ma sono certo che l'errore sta parlando del principale db.
Grazie per l'aiuto che puoi dare!
Codice di aggiornamento per il TDE principale:
--Create Master Key in Master Database
USE MASTER
GO
CREATE MASTER KEY ENCRYPTION BY PASSWORD = '1Password';
PRINT 'created master key'
go
--Backing up the master key file
USE master;
OPEN MASTER KEY DECRYPTION BY PASSWORD = '1Password';
BACKUP MASTER KEY TO FILE = '\\SERVERNAME\TDE_Master_Key.key' ENCRYPTION BY PASSWORD = '1Password';
GO
--Create Server Certificate in the Master Database encrypted with master key (created above) which would be used to create USER database encryption key.
USE Master
CREATE CERTIFICATE Cert_For_TDE WITH SUBJECT = 'Master_Cert_for_TDE', EXPIRY_DATE = '3500-Jan-01';
Go
--Backing up the server cert file
--USE master;
BACKUP CERTIFICATE Cert_For_TDE TO FILE = '\\SERVERNAME\TDE_Cert.cer'
WITH PRIVATE KEY ( FILE = '\\SERVERNAME\TDE_Cert_Key.key', ENCRYPTION BY PASSWORD = '1Password');
GO
--Create user database key
USE TDE
CREATE DATABASE ENCRYPTION KEY
WITH ALGORITHM = AES_256 ENCRYPTION BY SERVER CERTIFICATE Cert_For_TDE;
GO
--Enabling Transparent Database Encryption for the USER Database
USE master;
GO
ALTER DATABASE TDE SET ENCRYPTION ON
GO
Codice sul mirror per TDE:
--restore the backed up key to the mirror
use master
RESTORE MASTER KEY
FROM FILE = '\\SERVERNAME\TDE_Master_Key.key'
DECRYPTION BY PASSWORD = '1Password'
ENCRYPTION BY PASSWORD = '1Password';
GO
--restore the backed up cert to the mirror
USE Master;
OPEN MASTER KEY DECRYPTION BY PASSWORD = '1Password'
CREATE CERTIFICATE Cert_For_TDE
FROM FILE = '\\SERVERNAME\TDE_Cert.cer' WITH PRIVATE KEY ( FILE = '\\SERVERNAME\TDE_Cert_Key.key', DECRYPTION BY PASSWORD = '1Password');
GO
Update2 sys.database_mirroring_endpoints unito a sys.tcp_endpoints nello show principale:

sys.database_mirroring_endpoints uniti a sys.tcp_endpoints su Mirror show:
