The backup data needs to be stored, requiring a backup rotation scheme, [4] which is a system of backing up data to computer media that limits the number of backups of different dates retained separately, by appropriate re-use of the data storage media by overwriting of backups no longer needed. The scheme determines how and when each piece of ...
Encrypted data should remain encrypted when access controls such as usernames and password fail. Increasing encryption on multiple levels is recommended. Cryptography can be implemented on the database housing the data and on the physical storage where the databases are stored. Data encryption keys should be updated on a regular basis.
A clear disadvantage related to symmetric encryption is that sensitive data can be leaked if the private key is spread to individuals that should not have access to the data. [17] However, given that only one key is involved in the encryption process it can generally be said that speed is an advantage of symmetric encryption. [19]

Crypto-shredding 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". [1] This requires that the data have been encrypted.
