Encryption is a mechanism for protecting data, which applies to it a specially designed algorithm, effectively obfuscating its content by making it different from the original.
NOTE: If running Windows 2000 to utilize the higher levels of encryption, the Windows 2000 High Encryption Pack must be installed.
LiteSpeed offers the option of encrypting in the following formats:
Higher levels of encryption require slightly more CPU, but generally the impact of 256-bit AES encryption on a backup running on a modern server is very low at less than 0.5% CPU utilization. We recommend for best security of a backup that 256-bit AES be used when encryption is needed.
Caution: When encrypting data, take care not to lose the encryption key; a backup cannot be restored or recovered without the original encryption key.
