Methods and apparatus for storing and transmitting historical configuration data associated with information technology assets
Methods and apparatus for storing and transmitting historical configuration data associated with information technology assets are disclosed. The system reads and stores a first version of data with a timestamp. The system then performs a local update by reading a second version of data with a timestamp, replacing the first set of data and timestamp, and storing the changes between the first and second versions of data. The system also may receive update requests from a remote location for the latest version of data. The changes between versions of data are sent to the remote location, where the changes between versions of data are stored and are usable to create the requested latest version of data and/or prior versions of data.
