Patent ID: 8195612

Claim:
A method for improving a restoration, the method comprising: creating a catalog, wherein the catalog indicates at least one location of at least one data block stored on backup media, and the at least one data block is associated with a full backup stream and at least one differential incremental backup stream for at least one object; examining the catalog to identify at least one data block associated with a first differential incremental backup stream stored on the backup media; accessing the at least one data block associated with the first differential incremental backup stream from the backup media; examining the catalog to identify at least one data block associated with a second differential incremental backup stream stored on the backup media, wherein the second differential incremental backup stream is performed before the first differential incremental backup stream, and the at least one data block associated with the second differential incremental backup stream has at least one identifier that does not correspond with the at least one data block associated with the first differential incremental backup stream; accessing the at least one data block associated with the second differential incremental backup stream from the backup media; examining the catalog to identify at least one data block associated with the full backup stream stored on the backup media, wherein the at least one data block associated with the full backup stream has at least one identifier that does not correspond with the at least one data block associated with the first differential incremental backup stream and the at least one data block associated with the second differential incremental backup stream; accessing the at least one data block associated with the full backup stream from the backup media; and creating a data stream for restoring the at least one object, wherein the data stream is created using the at least one data block associated with the first differential incremental backup stream, the at least one data block associated with the second differential incremental backup stream, and the at least one data block associated with the full backup stream.
