The present invention relates to a method for performing an image level copy of an information store. The present invention comprises performing a snapshot of an information store that indexes the contents of the information store, retrieving data associated with the contents of the information store from a file allocation table, copying the contents of the information store to a storage device based on the snapshot, and associating the retrieved data with the copied contents to provide file system information for the copied contents.

1. A computing system that restores data to an information store, the method comprising: an information store;at least one storage manager in communication with the information store, the at least one storage manager comprising computer hardware, wherein the storage manager directs performance of a first snapshot of the information store at a first point in time, the first snapshot comprising first data about at least one file existing at the first point in time;at least one media agent in communication with the at least one storage manager, the at least one media agent copies at least the first data associated with the first snapshot to one or more remotely-located storage devices that are remotely located from the information store;the at least one media agent stores information about the first data in at least one map, the at least one map associates the first data with the first snapshot, and identifies the location of the first data in the one or more remotely-located storage devices;the storage manager directs performance of a second snapshot of the information store at a second point in time occurring after the first point in time, wherein the second snapshot indexes changed data that changed after the first point in time, wherein the changed data comprises portions of the at least one file that changed since the first point in time, wherein the at least one media agent copies the changed data indexed by the second snapshot to the one or more remotely located storage devices;the at least one media agent stores information about the changed data in the at least one map, wherein the at least one map associates the changed data with the second snapshot, and identifies the location of the changed data in the one or more remotely located storage devices; andthe at least one media agent restores to the information store a copy of the at least one file existing at the second point in time using the map in association with the first and second snapshots to restore from the one or more remotely-located storage devices at least a portion of the at least one file existing at the first point in time and the changed data existing at the second point in time. 2. The system of claim 1 wherein the changed data comprises file information obtained from a file access table. 3. The system of claim 1 wherein the information about the changed data comprises a copy of the changed data. 4. The system of claim 1 wherein the map identifies one or more previously saved snapshots where previous copies of the changed blocks were stored. 5. The system of claim 1 wherein the information about changed data comprises one or more file names associated with the changed data. 6. The system of claim 1 wherein the at least one media agent stores copies of the changed data in association with a previous snapshot. 7. The system of claim 1 further comprising a block filter to identify the changed blocks. 8. The system of claim 1 further comprising copy on write to identify the changed blocks. 9. The system of claim 1 wherein restoring the copy of the at least one file existing at the second point in time comprises restoring the copy of the at least one file from the first snapshot and replacing portions of the restored at least one file with the changed data from the second snapshot. 10. The system of claim 1 wherein restoring the copy of the at least one file existing at the second point in time comprises restoring portions of the at least one file from the second snapshot and adding at least a portion of the at least one file existing at the first point in time. 11. A method in a computing system of restoring data to an information store, the method comprising: storing instructions in a non-transitory computer storage which perform the following acts when executed by one or more computing devices;performing a first snapshot of an information store at a first point in time, the first snapshot comprising first data about at least one file existing at the first point in time;copying at least the first data associated with the first snapshot to one or more remotely-located storage devices that are remotely located from the information store;storing information about the first data in at least one map, the at least one map associates the first data with the first snapshot, and identifies the location of the first data in the one or more remotely-located storage devices;performing a second snapshot of the information store at a second point in time occurring after the first point in time, wherein the second snapshot indexes changed data that changed after the first point in time, wherein the changed data comprises portions of the at least one file that changed since the first point in time;copying the changed data indexed by the second snapshot to the one or more remotely located storage devicesstoring information about the changed data in the at least one map, wherein the at least one map associates the changed data with the second snapshot, and identifies the location of the changed data in the one or more remotely located storage devices; andrestoring from the one or more remotely-located storage devices to the information store, a copy of the at least one file existing at the second point in time using the map in association with the first and second snapshots to restore at least a portion of the at least one file existing at the first point in time and the changed data existing at the second point in time. 12. The method of claim 11 wherein the changed data comprises file information obtained from a file access table. 13. The method of claim 11 wherein the information about the changed data comprises a copy of the changed data. 14. The method of claim 11 wherein the map identifies one or more previously saved snapshots where previous copies of the changed blocks were stored. 15. The method of claim 11 wherein the information about the changed data comprises one or more file names associated with the changed data. 16. The method of claim 11 further comprising storing copies of the changed data in association with a previous snapshot. 17. The method of claim 11 wherein identifying the changed blocks uses a block filter to identify changes. 18. The method of claim 11 wherein identifying the changed blocks uses copy on write to identify changes. 19. The method of claim 11, wherein restoring the copy of the at least one file existing at the second point in time comprises restoring the copy of the at least one file from the first snapshot and replacing portions of the restored at least one file with the changed data from the second snapshot. 20. The method of claim 11, wherein restoring the copy of the at least one file existing at the second point in time comprises restoring portions of the at least one file from the second snapshot and adding at least a portion of the at least one file existing at the first point in time.
