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.

replacing the first configuration data set with the second configuration data set, wherein a second timestamp is stored with the second configuration data set, the second timestamp being chronologically after the first timestamp;
reading a third configuration data set at a third time;
replacing the second configuration data set with the third configuration data set, wherein a third timestamp is stored with the third configuration data set, the third timestamp being chronologically after the second timestamp;
persistently storing a first delta between the first configuration data set and the second configuration data set and a second delta between the second configuration data set and the third configuration data set after the third configuration data set replaced the first configuration data set to allow for a restore of any one of the first configuration data set and the second configuration data set;
