Abstract

A method, article of manufacture, and apparatus for processing data. In some embodiments, this includes analyzing a first container at a block level, determining a first text index of the first container, analyzing a second container at a block level, determining a second text index of the first container, and storing the first text index and the second text index in a backup catalog, wherein the backup catalog is stored in a storage device.

Claims

1. A method for processing data, comprising:

analyzing a first container at a block level;

determining a first text index of the first container, wherein the first text index includes a desktop search index, the desktop search index including a text content of at least one file in the first container;

analyzing a second container at a block level;

determining a second text index of the second container; and

storing the first text index and the second text index in a backup catalog, wherein the backup catalog is stored in a storage device.

2. The method as recited in claim 1, wherein the first container includes a Windows image.

3. The method as recited in claim 1, further comprising using the first text index and the second text index to perform a text search of files stored in the first and second container.

4. The method as recited in claim 1, wherein the at least one file includes an email message or a document.

5. A system for processing data, comprising a storage device, and a processor configured to:

analyze a first container at a block level;

determine a first text index of the first container, wherein the first text index includes a desktop search index, the desktop search index including a text content of at least one file in the first container;

analyze a second container at a block level;

determine a second text index of the second container; and

store the first text index and the second text index in a backup catalog, wherein the backup catalog is stored in the storage device.

6. The system as recited in claim 5, wherein the first container includes a Windows image.

7. The system as recited in claim 5, the processor further configured to use the first text index and the second text index to perform a text search of files stored in the first and second container.

8. A computer program product for processing data, comprising a non-transitory computer usable medium having machine readable code embodied therein for:

analyzing a first container at a block level;

determining a first text index of the first container, wherein the first text index includes a desktop search index, the desktop search index including a text content of at least one file in the first container;

analyzing a second container at a block level;

determining a second text index of the second container; and

storing the first text index and the second text index in a backup catalog, wherein the backup catalog is stored in a storage device.

9. The computer program product as recited in claim 8, wherein the first container includes a Windows image.

10. The computer program product as recited in claim 8, further comprising machine readable code for using the first text index and the second text index to perform a text search of files stored in the first and second container.
