Abstract

Generally described, embodiments of the present invention provide a system and method for determining what files of a consumer computer should have protection copies included in a backup and what files should be excluded from the backup. Additionally, embodiments of the present invention provide a method and system for recovering files and/or directories from multiple types of temporal versions, such as backup copies and total copies, and also provide the ability to recover from either local temporal versions or remote temporal versions. Still further, embodiments of the present invention provide the ability to only create a protection copy for a portion of a file that has changed since a previous protection copy of a file was created and stored.

Claims

1. A method for identifying files that are to be included in a backup copy, the method comprising:

identifying a file;

determining, based on a file extension of the identified file, if the identified file is to be excluded from a backup copy;

in response to determining that the identified file is not to be excluded based on the file extension, determining, based on a file location of the identified file, if the identified file is to be excluded from the backup copy; and

in response to determining that the identified file is not to be excluded based on the file location, including the identified file in a backup copy.

2. The method of claim 1, wherein including the identified file in a backup copy includes:

creating a protection copy of the identified file and including the protection copy in the backup copy.

3. The method of claim 1, further comprising:

determining, based on the file extension of the identified file, if the identified file is to be included in the backup copy.

4. The method of claim 3, wherein determining, based on the file extension of the identified file, if the identified file is to be included in the backup copy includes:

determining, based on a heuristic rule associated with a file location of the identified file, if the identified file is to be included in the backup copy.

5. The method of claim 4, wherein the heuristic rule identifies whether the identified file has been modified more recently than a directory containing the identified file.

6. The method of claim 1, wherein determining, based on a file location of the identified file, if the identified file is to be excluded from the backup copy, includes:

determining if a directory containing the file has an exclusion rule;

if it is determined that the directory has an exclusion rule, excluding the file from the backup copy;

if it is determined that the directory does not have an exclusion rule, determining if the directory has an inclusion rule;

if it is determined that the directory has an inclusion rule, including the identified file in the backup copy; and

if it is determined that the directory does not have an inclusion rule, excluding the identified file form the backup copy.

7. In a computer system having a computer-readable medium including a computer-executable program therein for performing the method of creating a protection copy of a chunk of a file, wherein a protection copy of the file has previously been created, the method comprising:

identifying a file that is to be protected;

partitioning the identified file into a plurality of chunks;

determining if a chunk matches a previous protection copy of a chunk;

if it is determined that the chunk does not match a previous protection copy of a chunk, creating a protection copy of the chunk; and

generating a chunk assembly list.

8. The computer system of claim 7, wherein determining if a chunk matches a previous protection copy of a chunk includes:

generating a chunk signature for the chunk;

comparing the generated chunk signature with a chunk signature of a previous protection copy of a chunk; and

if the generated chunk signature and the chunk signature of the previous protection copy of a chunk are different, determining that a temporal version of the chunk is to be created.

9. The computer system of claim 7, wherein the protection copy of the chunk is maintained at a location local to the file.

10. The computer system of claim 7, wherein the protection copy of the chunk is stored on a removable media.

11. The computer system of claim 7, wherein the chunk assembly list identifies the location of the protection copy of the chunk and an identification of a location of the previously created protection copy of the file.

12. The computer system of claim 7, wherein the chunk assembly list includes information for restoring the file from created protection copies of chunks.

13. The computer system of claim 7, wherein the protection copy of the chunk is maintained on a first item of media and the previously created protection copy of the file is maintained on a second item of media.

14. In a user backup system having a remote storage location, a computer with a nonremovable storage medium, a removable storage media, and a method for restoring a file, the method comprising:

identifying a plurality of protection copies of the file contained in a plurality of temporal versions, wherein a first temporal version is a local temporal version and wherein a second temporal version is a remote temporal version;

generating a list including an identification of a first protection copy of the file contained in the first temporal version and an identification of a second protection copy of the file contained in the second temporal version;

receiving a selection of an identified protection copy of the file from the generated list;

obtaining the temporal version associated with the selected option; and

recovering the file.

15. The user backup system of claim 14, further comprising:

determining if any of the plurality of temporal versions includes a same protection copy of the file; and

wherein the generated list does not include an identification of any remote temporal versions that include a same protection copy of the file as a local temporal version.

16. The user backup system of claim 15, wherein the local temporal versions may be local available temporal versions, local networked temporal versions, or local obtainable temporal versions.

17. The user backup system of claim 16, wherein the local obtainable temporal versions are stored on removable media.

18. The user backup system of claim 17, wherein the removable media is randomly accessible media.

19. The user backup system of claim 14, wherein the identified local temporal versions include a plurality backup copies that contain protection copies of the file, wherein each of the plurality of backup copies is located on separate items of removable media.

20. The user backup system of claim 14, wherein the remote temporal version identifies a location and timestamp for the protection copy of the file contained in the remote temporal version.
