(iii) present in response to the search criteria a fast-forward progression through the mounted smaller portions of respective archive copies that satisfy the one or more search criteria, without restoring the respective archive copies in their entireties to the user computing device.

2. The computing device of claim 1 wherein, for any given data file being archived to a respective archive copy, the executable indexer is further configured to:

(d) divide the respective archive copy into the content-indexed smaller portions.

3. The computing device of claim 1 further comprising:

a playback agent configured to, in response to a request for playback of a first smaller portion of a respective archive copy presented in the fast-forward progression, causes the first smaller portion to be restored to the user computing device from a secondary storage device comprising the respective archive copy.

4. The computing device of claim 1 wherein the executable search filter is further configured to accept search criteria for content attributes, including at least one of:

textual content, picture content, video content, and audio content.

5. The computing device of claim 1 wherein the executable indexer is further configured to:

(d) for the one or more data files being archived, generate a searchable file-attribute index comprising file attributes for each respective archive copy, and

(e) associate the file-attribute index with the respective archive copies.

6. The computing device of claim 1 wherein the executable indexer is further configured to:

(d) for the one or more data files being archived, generate a searchable file-attribute index comprising file attributes for each respective archive copy, and

(e) associate the file-attribute index with the respective archive copies; and

wherein the one or more search criteria also comprise at least one file attribute and wherein the executable search filter is further configured to also search in the file-attribute index for the at least one file attribute.

7. The computing device of claim 1 wherein the content index is stored to the computing device.

8. The computing device of claim 1 wherein the content index is stored to a user computing device that is associated with the data files being archived.

9. The computing device of claim 1 further comprising an executable media agent that comprises the executable indexer and the executable search filter, and wherein the media agent generates the archive copies being indexed.

10. A computer-readable medium, excluding transitory propagating signals, storing instructions that, when executed by a computing device, which comprises one or more processors and computer memory, cause the computing device to perform operations for content indexing of data files being archived, the operations comprising:

executing an indexer that, in the course of one or more data files being archived to respective archive copies, indexes the one or more data files according to content attributes, including at least one of;

textual content, picture content, video content, and audio content,

wherein each archive copy is stored offline relative to a user computing device that is distinct from the computing device executing the indexer;

(a) associating by the indexer content attributes with respective smaller portions of each archive copy,

(b) for the one or more data files being archived, generating by the indexer a searchable content index of associated content attributes relative to the smaller portions of each archive copy, and

(c) associating by the indexer the content index with the respective archive copies; and

executing a search filter that is configured to;

(i) search in the content index for one or more search criteria received from the user computing device,

(ii) cause only smaller portions of respective archive copies that satisfy the one or more search criteria, to be mounted to the user computing device,

wherein archive copies and smaller portions thereof that do not satisfy the one or more search criteria are not mounted and remain offline to the user computing device, and

(iii) present in response to the search criteria a fast-forward progression through the mounted smaller portions of respective archive copies that satisfy the one or more search criteria, without restoring the respective archive copies in their entireties to the user computing device.

11. The computer-readable medium of claim 10 wherein, for any given data file being archived to a respective archive copy:

(d) dividing by the indexer the respective archive copy into the content-indexed smaller portions.

12. The computer-readable medium of claim 10, the operations further comprising:
