Abstract

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.

Claims

1. A method for storing historical configuration data associated with an information technology asset, the method comprising:

reading a first configuration data set from a machine at a first time;

storing the first configuration data, wherein a first timestamp is stored with the first configuration data set;

reading a second configuration data set at a second time;

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; and

persistently storing a first reverse delta between the first configuration data set and the second configuration data set and a second reverse 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.

2. The method of claim 1, further comprising:

reading a fourth configuration data set at a fourth time;

replacing the third configuration data set with the fourth configuration data set, wherein a fourth timestamp is stored with the fourth configuration data set, the fourth timestamp being chronologically after the third timestamp; and

persistently storing a third reverse delta between the third configuration data set and the fourth configuration data set to allow for a restore of any one of the first configuration data set, the second configuration data set, and the third configuration data set.

3. The method of claim 1, wherein the information technology asset is a physical machine.

4. The method of claim 1, wherein the information technology asset is a virtual machine.

5. An apparatus for storing historical configuration data associated with an information technology asset, the apparatus comprising:

a processor; and

a storage device, the storage device storing a software program structured to cause the processor to;

read a first configuration data set from a machine at a first time;

store the first configuration data, wherein a first timestamp is stored with the first configuration data set;

read a second configuration data set at a second time;

replace 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;

read a third configuration data set at a third time;

replace 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; and

persistently store a first reverse delta between the first configuration data set and the second configuration data set and a second reverse 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.

6. The apparatus of claim 5, wherein the software program is structured to cause the processor to:

read a fourth configuration data set at a fourth time;

replace the third configuration data set with the fourth configuration data set, wherein a fourth timestamp is stored with the fourth configuration data set, the fourth timestamp being chronologically after the third timestamp; and

persistently store a third reverse delta between the third configuration data set and the fourth configuration data set to allow for a restore of any one of the first configuration data set, the second configuration data set, and the third configuration data set.

7. The apparatus of claim 5, wherein the information technology asset is a physical machine.

8. The apparatus of claim 5, wherein the information technology asset is a virtual machine.

9. A machine readable media storing instructions structured to cause an apparatus for storing historical configuration data associated with an information technology asset to:

read a first configuration data set from a machine at a first time;

store the first configuration data, wherein a first timestamp is stored with the first configuration data set;

read a second configuration data set at a second time;

replace 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;

read a third configuration data set at a third time;

replace 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; and

persistently store a first reverse delta between the first configuration data set and the second configuration data set and a second reverse 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.

10. The machine readable media of claim 9, wherein the instructions are structured to cause the apparatus to:

read a fourth configuration data set at a fourth time;

replace the third configuration data set with the fourth configuration data set, wherein a fourth timestamp is stored with the fourth configuration data set, the fourth timestamp being chronologically after the third timestamp; and

persistently store a third reverse delta between the third configuration data set and the fourth configuration data set to allow for a restore of any one of the first configuration data set, the second configuration data set, and the third configuration data set.

11. The machine readable media of claim 9, wherein the information technology asset is a physical machine.

12. The machine readable media of claim 9, wherein the information technology asset is a virtual machine.
