Note: Is is the Database Master Key (DMK). It is not the Service Master Key (SMK). The database master key is a symmetric key used to protect the private keys of certificates and asymmetric keys that are present in the database. When it is created, the master key is encrypted by using the AES_256 algorithm and a user-supplied password. Database master key is stored in both... » read more
Note: This is for Service Master Key (SMK). This is not the same as Database Master Key (DMK). The service master key is the root of the SQL Server encryption hierarchy. The service master key directly or indirectly secures all other keys in the tree. If a dependent key cannot be decrypted during a forced... » read more
SQL Server uses encryption keys to help secure data, credentials, and connection information that is stored in a server database. SQL Server has two kinds of keys: symmetric and asymmetric. Symmetric keys use the same password to encrypt and decrypt data. Asymmetric keys use one password to encrypt data (called the public key) and another to decrypt data (called... » read more
Back up the master key and certificate that are used for TDE to a safe location. The master key and certificate are required to restore backups that were taken when the database was encrypted with TDE. After you remove the database encryption key, take a log backup followed by a fresh full backup of the... » read more
TDE and Always On To configure the TDE on the TDE_Test database, we should first create a master key in the master database. Only one master key can be created per each SQL Server instance. All user databases that are hosted in the same SQL instance, and have the TDE enabled on it, will share... » read more
Create Database Master Key and Certificate Note: USE master database. You should backup the Certificate (With Master Key) as soon as you create the certificate. Note: You can not create a Master Key if a Master Key is already created. You can not drop a Master Key if there are existing Certificate created with the... » read more

Note: sp_spaceused is the fastest way to get a list of table size of the database. sp_spaceused Note: This query is the most detailed. It breaks out the Used space to Data Space and Index Space. ReservedSpace = DataSpace + IndexSize + UnusedSpace Total Space Note: Total Space includes both Used Space (Data + Index)... » read more
