Encrypting the database backups helps secure the data: SQL Server provides the option to encrypt the backup data while creating a backup. Encryption can also be used for databases that are encrypted using TDE. Encryption is supported for backups done by SQL Server managed backup to Microsoft Az...
Raising the security bar through releases, SQL Server 2014 now enables to encrypt database backups natively. It has been a long awaited feature, as the options to cover this need were rather cumbersome :- Transparent Data Encryption, released with SQL Server 2008, but it implies some CPU ...
If transparent data encryption is used to encrypt an entire database, compressing backups might not reduce their size by much, if at all. Whether the database is compressed. If the database is compressed, compressing backups might not reduce their size by much, if at all. See Also Tasks...
The backup process works on a data page basis : it copies data pages from the data files into the backup file. Since SQL Server 2008, we can compress database backups. This feature is supported by an algorithm similar to the ones behind file compression software : it factorizes patterns o...
Learn about compression of SQL Server backups, including restrictions, performance trade-offs, Configuring backup compression, and the compression ratio.
首先看服务主密钥。很简单,在 BACKUP SERVICE MASTER KEY语句中使用一个文 件路径(可以是一个本地或UNC路径),以及一个满足密码复杂度要求的密码。备份文件时 使用密码可以防止他人将您的主密钥还原到另一台服务器上,然后解密您的数据库主密钥。 下列示例将把服务主密钥的备份保存到C:\KeyBackups文件夹(此文件夹...

Digging a bit more into this, Encrypted Backups use a certificate or an asymmetric key along with an encryption algorithm to encrypt the backup file when a backup is performed. This only affects the backup file, not the actual data in the database. As it was explained above, Always Encrypt...
Always Encrypted is a new feature in SQL Server 2016, which encrypts the data both at rest *and* in motion (and keeps it encrypted in memory). So this protects the data from rogue administrators, backup thieves, and man-in-the-middle attacks. Unlike TDE, as well, Always Encrypted allows...
