Abstract

A system and method for managing data in a computer system. A backup server is configured to harvest data indicative of logical relationships among data entries in a backup data set. The harvested data and backup data set are stored on a backup medium. Catalog entries are created for both the backup data set and the harvested data. The computer system allows a user to browse the backup catalog, including the logical structure of the content of a particular backup data set. The user may select particular items for restoration from the catalog. In response, the server restores the backup data set and harvested data to a temporary location, identifies data in the harvested data which corresponds to the user'"'"'s selections, searches the backup data set for the selected items, and initiates restoration of the selected items.

Claims

1. A method for managing data in a computer system, the method comprising:

creating a backup data set comprising a plurality of data entries;

harvesting a harvested data set from the backup data set, wherein said harvesting comprises determining and storing a logical relationship among the plurality of data entries of the backup data set;

associating the harvested data set with the backup data set;

storing the harvested data set and the backup data set on a backup medium; and

creating and storing entries in a backup catalog which correspond to the harvested data set and the backup data set, said entries comprising a user-searchable view of contents of the harvested data set.

2. The method of claim 1, further comprising:

creating a plurality of backup data sets, corresponding harvested data sets, and corresponding entries in the backup catalog;

browsing harvested data set entries in the backup catalog;

selecting one or more items from the harvested data set entries in the backup catalog;

restoring a harvested data set and a corresponding backup data set that correspond to the one or more items selected from the harvested data set entries in the backup catalog to a temporary location;

identifying corresponding data within the harvested data set as restored which corresponds to the selected one or more items; and

utilizing the corresponding data to restore corresponding data from the backup data set as restored to a live data set.

3. The method of claim 2, wherein said identifying comprises performing a search of the harvested data set as restored for references which correspond to the selected one or more items.

4. The method of claim 2, wherein the logical relationship comprises a hierarchy of groups and each data entry of the plurality of data entries is a member of one or more of said groups.

5. The method of claim 4,

wherein each data entry comprises one or more values, each value corresponding to a selection parameter of one or more pre-determined selection parameters;

wherein each harvested data set includes a plurality of references, each of said references corresponding to one of the plurality of data entries; and

wherein each of said references comprises data corresponding to the one or more values of a corresponding data entry.

6. The method of claim 4, wherein harvesting a data set comprises:

associating each of a plurality of references with one or more of the groups; and

for each of the plurality of data entries, storing data which corresponds to one or more values of a given data entry in a corresponding reference.

7. A computer system comprising:

a backup data set comprising a plurality of data entries; and

a backup server coupled to a data storage device;

wherein the backup server is configured to;

harvest a harvested data set from the backup data set, wherein harvesting the harvested data set comprises determining and storing a logical relationship among the plurality of data entries of the backup data set;

associate the harvested data set with the backup data set;

store the harvested data set and the backup data set on the data storage device; and

create and store entries in a backup catalog which correspond to the harvested data set and the backup data set, said entries comprising a user-searchable view of contents of the harvested data set.

8. The computer system of claim 7, wherein the backup server is further configured to:

create a plurality of backup data sets, corresponding harvested data sets, and corresponding entries in the backup catalog;

display an interface which enables a user to;

browse harvested data set entries in the backup catalog; and

select one or more items from the harvested data set entries in the backup catalog;

restore a harvested data set and a corresponding backup data set that correspond to the one or more items selected from the harvested data set entries in the backup catalog to a temporary location;

identify corresponding data within the harvested data set as restored which corresponds to the selected one or more items; and

utilize the corresponding data to restore corresponding data from the backup data set as restored to a live data set.

9. The computer system of claim 8, wherein the one or more items includes one or more:

groups with which one or more references in the harvested data set as restored are associated; and

/or

selected values which corresponds to a pre-determined selection parameter.

10. The computer system of claim 9,

wherein the plurality of data entries include one or more of an e-mail message, an e-mail attachment, and an e-mail mailbox;

and/or

wherein the selection parameters include one or more of a timestamp, a task name, a folder name, a sender name, a recipient name, a mailbox name, and a sender address.

11. The computer system of claim 8, wherein the logical relationship comprises a hierarchy of groups and each data entry is a member of one or more of said groups.

12. The computer system of claim 10,

wherein each data entry comprises one or more values, each value corresponding to a selection parameter of one or more pre-determined selection parameters;

wherein each harvested data set includes a plurality of references, each of said references corresponding to one of the plurality of data entries; and

wherein each of said references comprises data corresponding to the one or more values of a corresponding data entry.

13. The computer system of claim 11, wherein harvesting a data set comprises:

associating each of a plurality of references with one or more of the groups; and

for each of the plurality of data entries, storing data which corresponds to one or more values of a given data entry in a corresponding reference.

14. A computer storage medium storing computer instructions for managing data in a computer system, wherein the instructions are executable to:

create a backup data set comprising a plurality of data entries;

harvest a harvested data set from the backup data set, wherein harvesting the harvested data set comprises determining and storing a logical relationship among the plurality of data entries of the backup data set;

associate the harvested data set with the backup data set;

store the harvested data set and the backup data set on a backup medium; and

create and store entries in a backup catalog which correspond to the harvested data set and the backup data set, said entries comprising a user-searchable view of contents of the harvested data set.

15. The computer storage medium claim 14, wherein the instructions are further executable to:

create a plurality of backup data sets, corresponding harvested data sets, and corresponding entries in the backup catalog;

display an interface which enables a user to;

browse harvested data set entries in the backup catalog; and

select one or more items from the harvested data set entries in the backup catalog;

restore a harvested data set and a corresponding backup data set that correspond to the one or more items selected from the harvested data set entries in the backup catalog to a temporary location;

identify corresponding data within the harvested data set as restored which corresponds to the selected one or more items; and

utilize the corresponding data to restore corresponding data from the backup data set as restored to a live data set.
