Abstract

Claims (37)

1. A method for managing file based backups (FBBs), the method comprising:

obtaining, by a backup agent, a backup request for a FBB;

in response to the backup request, generating a FBB;

identifying a compression ratio of a previous FBB metadata file;

making a determination, based on the compression ratio, that the FBB metadata file does not require an assessment; and

based on the determination, identifying a set of attribute regions, wherein the set of attribute regions are associated with the previous FBB metadata file;

generating the FBB metadata file corresponding to the FBB, wherein the FBB metadata file comprises the set of attribute regions;

performing, using the set of attribute regions, a deduplication on the FBB metadata file to obtain a deduplicated FBB metadata file; and

storing the deduplicated FBB metadata file in a backup storage system.

2. The method of claim 1 , wherein the determination is based on a compression ratio threshold.

3. The method of claim 1 , wherein the set of attribute regions comprises a constant attribute region and a plurality of variable attribute regions.

4. The method of claim 3 , wherein the constant attribute region comprises at least one of: a file identifier attribute, a parent file identifier and a container identifier.

5. The method of claim 3 , wherein a variable attribute region of the plurality of variable attribute regions comprises at least one of: a file size, a hash value of a file, and an offset of the file.

6. A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method for managing file based backups (FBBs), the method comprising:

obtaining, by a backup agent, a backup request for a FBB;

in response to the backup request, generating a FBB;

identifying a compression ratio of a previous FBB metadata file;

making a determination, based on the compression ratio, that a FBB metadata file does not require an assessment; and

based on the determination, identifying a set of attribute regions, wherein the set of attribute regions are associated with the previous FBB metadata file;

generating the FBB metadata file corresponding to the FBB, wherein the FBB metadata file comprises the set of attribute regions;

performing, using the set of attribute regions, a deduplication on the FBB metadata file to obtain a deduplicated FBB metadata file; and

storing the deduplicated FBB metadata file in a backup storage system.

7. The non-transitory computer readable medium of claim 6 , wherein the determination is based on a compression ratio threshold.

8. The non-transitory computer readable medium of claim 6 , wherein the set of attribute regions comprises a constant attribute region and a plurality of variable attribute regions.

9. The non-transitory computer readable medium of claim 8 , wherein the constant attribute region comprises at least one of: a file identifier attribute, a parent file identifier and a container identifier.

10. The non-transitory computer readable medium of claim 8 , wherein a variable attribute region of the plurality of variable attribute regions comprises at least one of: a file size, a hash value of a file, and an offset of the file.

11. A system comprising:

a processor; and

memory comprising instructions, which when executed by the processor, perform a method comprising:

obtaining, by a backup agent, a backup request for a FBB;

in response to the backup request, generating a FBB;

identifying a compression ratio of a previous FBB metadata file;

making a determination, based on the compression ratio, that a FBB metadata file does not require an assessment; and

based on the determination, identifying a set of attribute regions, wherein the set of attribute regions are associated with the previous FBB metadata file;

generating the FBB metadata file corresponding to the FBB, wherein the FBB metadata file comprises a set of attribute regions;

performing, using the set of attribute regions, a deduplication on the FBB metadata file to obtain a deduplicated FBB metadata file; and

storing the deduplicated FBB metadata file in a backup storage system.
