System and method for information handling system multi-level authentication for backup services

An information handling system comprising:

• an information processing node having a processor operable to generate information for storage and retrieve information from storage, the information processing node accessing information according to a first authentication mechanism;
• a storage node having a processor and a storage medium, the storage node interfaced with the information processing node through a network, the storage medium storing information according to a second authentication mechanism;
• an authentication node interfaced with the network and operable to authenticate information requests under the first authentication mechanism;
• and
• a data management application executing on the information processing node processor and operable to interact with the storage node to retrieve information, the data management application further operable to authenticate communications with the storage node by a message of the second authentication mechanism that includes information of the first authentication mechanism;
• wherein the storage node is further operable to authenticate communications of the data management application by communicating the information of the first authentication mechanism to the authentication node;
• and
• wherein the information of the first authentication mechanism comprises a domain of less than all information stored on the storage medium.
