This article describes how to back up and restore a database containing columns protected with Always Encrypted.
When you back up a database, the resulting backup file contains encrypted stored in encrypted columns and all metadata for Always Encrypted keys.
When you restore a database, all encrypted data and all metadata for Always Encrypted keys are restored.
If you restored the database on a different server or under a different name, you don't need to do anything special to enable the application to query the encrypted data in the target database, as the keys in both databases are the same.
