Encryption is an increasingly important set of technologies, used to safeguard private data in computers, across public or private networks, or in other machine-readable forms. There are specific and unique issues of data protection and encryption relating to data backup solutions; these need to be understood and integrated into an organization's broader business-continuity plans. Encryption functions as an additional layer of protection, built on top of a solid core mechanism for data backup, protection, archiving, and disaster-recovery. All encryption methods depend on "Keys" to perform the transformation of "Plain Text" (which is a term of art in cryptography, meaning unencrypted data, whether textual in nature or otherwise) into "Cipher Text." Keys, like conventional passwords, can have varying degrees of "Strength." And like passwords, they must be carefully managed to ensure privacy, and to protect against loss of the key itself. Well-encrypted information simply cannot be unencrypted without the original key; for this reason, loss of the key represents an equally-large risk to the data owner as exposure of the underlying data itself may. Unitrends' InCrypt capability meets all these requirements, and is fully-integrated into the company's family of Data Protection Unit (DPU) and Data Protection Vault (DPV) appliances. This paper explains how keys can be used for data protection. It is a smart layer of protection that saves companies especially financial institutions like banks from crisis that may threaten its existence.
