Abstract

Claims (50)

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

obtaining, by a FBB metadata file manager, a FBB mount request for a FBB mount of a FBB from an application, wherein the application is executing in a production host environment, and wherein the FBB comprises file system data comprising data tags and a FBB metadata file;

in response to the FBB mount request, the FBB metadata file manager:

identifies a FBB in a backup storage system;

obtains the FBB metadata file corresponding to the FBB from the backup storage system;

performs an attribute analysis to identify storage location attributes in the FBB metadata file;

stores a FBB virtual file system in the production host environment using the storage location attributes; and

enables access to the FBB virtual file system by the application;

obtaining, from the application, a file request for at least a portion of the file system data stored in the FBB;

in response to the file request:

identifying a storage of the portion of the file system data in the backup storage system via the FBB virtual file system;

initiating generation of a temporary storage device, separate from the backup storage system, that comprises a copy of the portion of the file system data from the backup storage system, wherein the copy does not include data tags; and

initiating access to the temporary storage device by the application.

2. The method of claim 1 , wherein the FBB is stored in a common data streaming format (CDSF).

3. The method of claim 1 , wherein the FBB metadata file comprises a plurality of root paths for a file system of the FBB.

4. The method of claim 1 , wherein the storage location attributes comprise at least one of: a file identifier attribute, a parent file identifier and a container identifier, a file size, a hash value, and an offset.

5. 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 FBB metadata file manager, a FBB mount request for a FBB mount of a FBB from an application, wherein the application is executing in a production host environment, and wherein the FBB comprises file system data comprising data tags and a FBB metadata file;

in response to the FBB mount request, the FBB metadata file manager:

identifies a FBB in a backup storage system;

obtains the FBB metadata file corresponding to the FBB from the backup storage system;

performs an attribute analysis to identify storage location attributes in the FBB metadata file;

stores a FBB virtual file system in the production host environment using the storage location attributes; and

enables access to the FBB virtual file system by the application;

obtaining, from the application, a file request for at least a portion of the file system data stored in the FBB;

in response to the file request:

identifying a storage of the portion of the file system data in the backup storage system via the FBB virtual file system;

initiating generation of a temporary storage device, separate from the backup storage system, that comprises a copy of the portion of the file system data from the backup storage system, wherein the copy does not include data tags; and

initiating access to the temporary storage device by the application.

6. The non-transitory computer readable medium of claim 5 , wherein the FBB is stored in a common data streaming format (CDSF).

7. The non-transitory computer readable medium of claim 5 , wherein the FBB metadata file comprises a plurality of root paths for a file system of the FBB.

8. The non-transitory computer readable medium of claim 5 , wherein the storage location attributes comprise at least one of: a file identifier attribute, a parent file identifier and a container identifier, a file size, a hash value, and an offset.

9. A system comprising:

a processor; and

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

obtaining, by a FBB metadata file manager, a FBB mount request for a FBB mount of a FBB from an application, wherein the application is executing in a production host environment, and wherein the FBB comprises file system data comprising data tags and a FBB metadata file;

in response to the FBB mount request, the FBB metadata file manager:

identifies a FBB in a backup storage system;

obtains the FBB metadata file corresponding to the FBB from the backup storage system;

performs an attribute analysis to identify storage location attributes in the FBB metadata file;

stores a FBB virtual file system in the production host environment using the storage location attributes; and

enables access to the FBB virtual file system by the application;

obtaining, from the application, a file request for at least a portion of the file system data stored in the FBB;

in response to the file request:

identifying a storage of the portion of the file system data in the backup storage system via the FBB virtual file system;

initiating generation of a temporary storage device, separate from the backup storage system, that comprises a copy of the portion of the file system data from the backup storage system, wherein the copy does not include data tags; and

initiating access to the temporary storage device by the application.

10. The system of claim 9 , wherein the FBB is stored in a common data streaming format (CDSF).

11. The system of claim 9 , wherein the FBB metadata file comprises a plurality of root paths for a file system of the FBB.

12. The system of claim 9 , wherein the storage location attributes comprise at least one of: a file identifier attribute, a parent file identifier and a container identifier, a file size, a hash value, and an offset.
