Abstract

A backup and restoration process which first attempts to recover information blocks from locally connected information handling systems executing a backup/restore service before looking to the slower access cloud store to recover data blocks.

Claims

1. A method for allowing restoration of information to an information handling system using information from other information handling systems comprising:

storing information from all information handling systems on a network to an off site datastore;

creating a common database, the common database cataloging information stored to the off site datastore;

storing the common database of the cataloged information to the off site datastore;

creating individual respective catalogs of information stored to the off site datastore for respective information handling systems on the network;

storing in a database identities of all information handling systems in the network;

determining whether a restoration is desirable; and

,

when a restoration is desirable,

booting an information handling system to be restored to restoration media;

obtaining, via the information handling system to be restored, access to the database describing identities of information handling systems in the network;

recovering information for restoration from other functioning information handling system on the network as possible;

determining whether there is any additional information to be restored that is not available from the functioning information handling systems; and

,

if there is any additional information to be restored, then obtaining the additional information from the off site datastore.

2. The method of claim 1 wherein:

the backup process uses a server application where the server application enables local storage of the information and the common database

3. The method of claim 1 wherein:

the storing information from all information handling systems on a network to an off site datastore performs an equivalency operation of information to be stored to the off site datastore and stores single copies of equivalent information to the off site datatore.

4. The method of claim 3 wherein:

the equivalency operation identifies cluster hashes of information blocks to be stored to the off site datastore.

5. The method of claim 1 wherein:

the restoration media comprises at least one of a compact disk (CD), a digital video disk (DVD) and a universal serial bus (USB) memory device.

6. The method of claim 1 wherein:

other information handling systems on the network also comprise respective caches of their respective databases for enhanced rapid access.

7. The method of claim 1 wherein:

the recovering equivalent information from functioning information handling systems on the network performs a cluster operation to determine whether the functioning information handling system have a byte for byte equivalent of the information to be restored.

15. The method of claim 1 wherein:

the recovering equivalent information from functioning information handling systems on the network performs a cluster operation to determine whether the functioning information handling system have a byte for byte equivalent of the information to be stored.

8. A method for performing a backup operation, the backup operation enabling restoration of information to an information handling system using information from other information handling systems comprising:

storing information from all information handling systems on a network to an off site datastore;

creating a common database, the common database cataloging information stored to the off site datastore;

storing the common database of the cataloged information to the off site datastore;

creating individual respective catalogs of information stored to the off site datastore for respective information handling systems on the network; and

,

storing in a database identities of all information handling systems in the network.

9. The method of claim 8 wherein:

the backup process uses a server application where the server application enables local storage of the information and the common database

10. The method of claim 8 wherein:

the storing information from all information handling systems on a network to an off site datastore performs an equivalency operation of information to be stored to the off site datastore and stores single copies of equivalent information to the off site datatore.

11. The method of claim 10 wherein:

the equivalency operation identifies cluster hashes of information blocks to be stored to the off site datastore.

12. A method for performing a restoration of information to an information handling system using information from other information handling systems on a network comprising:

booting an information handling system to be restored to restoration media;

obtaining, via the information handling system to be restored, access to a database describing identities of information handling systems in the network;

recovering information for restoration from other functioning information handling system on the network as possible;

determining whether there is any additional information to be restored that is not available from the functioning information handling systems; and

,

if there is any additional information to be restored, then obtaining the additional information from an off site datastore.

13. The method of claim 12 wherein:

the restoration media comprises at least one of a compact disk (CD), a digital video disk (DVD) and a universal serial bus (USB) memory device.

14. The method of claim 12 wherein:

other information handling systems on the network also comprise respective caches of respective databases for enhanced rapid access.
