Transparent Data Encryption (often abbreviated to TDE) is a technology employed by Microsoft, IBM and Oracle to encrypt database files. TDE offers encryption at file level. TDE enables the encryption of data at rest, encrypting databases both on the hard drive and consequently on backup media. It does not protect data in transit nor data in use.
encrypt prior of destage = files are encrypted on the cloud storage gateway and destaged to object storage in an encrypted form; compress and/or deduplication prior of destage = files are deduplicated and/or compressed prior of destaging; backup data in a native backup format; Combinations of these functions are usual.

Data encryption, which prevents data visibility in the event of its unauthorized access or theft, is commonly used to protect data in motion and increasingly promoted for protecting data at rest. [9] The encryption of data at rest should only include strong encryption methods such as AES or RSA. Encrypted data should remain encrypted when ...
In other words, the files are "copied" (e.g. into the backup file) in encrypted form, and are not decrypted during backup. Starting with Windows Vista , a user's private key can be stored on a smart card ; Data Recovery Agent (DRA) keys can also be stored on a smart card.
Encryption in transit protects data as it is being transmitted to and from the cloud service. [20] Encryption at rest protects data that is stored at the service provider. Encrypting data in an on-premises cloud service on-ramp system can provide both kinds of encryption protection. There are several options available to avoid security issues.
Particular data binary large objects can be encrypted in a way that salt is added and/or an external user-prompted password (aka "Strong Key Protection") is required. The use of a salt is a per-implementation option – i.e. under the control of the application developer – and is not controllable by the end user or system administrator.
Client-side encryption is the cryptographic technique of encrypting data on the sender's side, before it is transmitted to a server such as a cloud storage service. [1] Client-side encryption features an encryption key that is not available to the service provider, making it difficult or impossible for service providers to decrypt hosted data.
Crypto-shredding or crypto erase (cryptographic erasure) is the practice of rendering encrypted data unusable by deliberately deleting or overwriting the encryption keys: assuming the key is not later recovered and the encryption is not broken, the data should become irrecoverable, effectively permanently deleted or "shredded".
