Abstract

Claims (70)

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

obtaining, by a FBB metadata file manager and by an application, a file request for a file stored in a FBB, wherein the FBB is stored in a backup storage system;

identifying, using a FBB metadata file of the FBB, a storage location of the file, and wherein the FBB comprises file system data and the FBB metadata file;

initiating generation of a temporary storage device, wherein initiating the generation of the temporary storage device comprises prompting a FBB temporary storage device manager of a backup agent to partition a portion of storage of the backup agent for the temporary storage device;

storing, by the FBB temporary storage device manager, a copy of the file in the temporary storage device using the storage location and the FBB;

initiating, after the storing, access to the copy of the file for the application;

writing, based on a write request obtained from the application, to the copy of the file in the temporary storage device to obtain an updated copy of the file;

deleting the temporary storage device in response to generation of a second FBB, wherein the second FBB corresponds to the updated copy of the file;

prior to obtaining the file request:

obtaining, by the FBB metadata file manager, a FBB mount request for a FBB mount of the FBB from the application, wherein the application is executing in a production host environment;

in response to the FBB mount request:

identifying the FBB in a backup storage system;

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

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

storing a FBB virtual file system in the production host environment using the attributes of the storage location;

enabling access to the FBB virtual file system by the application, wherein enabling access to the FBB virtual file system comprises:

obtaining a read request for data in the file system data from the application;

identifying, using the FBB virtual file system, a file path based on the storage of the file system data in the backup storage system; and

based on the file path, obtaining the data from the backup storage system; and

providing the data to 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 attributes of the storage location comprise at least one of: a file identifier attribute, a parent file identifier and a container identifier, a file size, a hash value of a file, and an offset of the file.

4. The method of claim 1 , wherein the file system data comprises data tags.

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 and by an application, a file request for a file stored in a FBB, wherein the FBB is stored in a backup storage system;

identifying, using a FBB metadata file of the FBB, a storage location of the file, wherein the FBB comprises file system data and the FBB metadata file;

initiating generation of a temporary storage device, wherein initiating the generation of the temporary storage device comprises prompting a FBB temporary storage device manager of a backup agent to partition a portion of storage of the backup agent for the temporary storage device;

storing, by the FBB temporary storage device manager, a copy of the file in the temporary storage device using the storage location and the FBB;

initiating, after the storing, access to the copy of the file for the application;

writing, based on a write request obtained from the application, to the copy of the file in the temporary storage device to obtain an updated copy of the file;

deleting the temporary storage device in response to generation of a second FBB, wherein the second FBB corresponds to the updated copy of the file;

prior to obtaining the file request:

obtaining, by the FBB metadata file manager, a FBB mount request for a FBB mount of the FBB from the application, wherein the application is executing in a production host environment;

in response to the FBB mount request:

identifying the FBB in a backup storage system;

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

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

storing a FBB virtual file system in the production host environment using the attributes of the storage location;

enabling access to the FBB virtual file system by the application, wherein enabling access to the FBB virtual file system comprises:

obtaining a read request for data in the file system data from the application;

identifying, using the FBB virtual file system, a file path based on the storage of the file system data in the backup storage system; and

based on the file path, obtaining the data from the backup storage system; and

providing the data to 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 attributes of 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 of a file, and an offset of the file.

8. The non-transitory computer readable medium of claim 5 , wherein the file system data comprises data tags.

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 and by an application, a file request for a file stored in a FBB, wherein the FBB is stored in a backup storage system;

identifying, using a FBB metadata file of the FBB, a storage location of the file, wherein the FBB comprises file system data and the FBB metadata file;

initiating generation of a temporary storage device, wherein initiating the generation of the temporary storage device comprises prompting a FBB temporary storage device manager of a backup agent to partition a portion of storage of the backup agent for the temporary storage device;

storing, by the FBB temporary storage device manager, a copy of the file in the temporary storage device using the storage location and the FBB;

initiating, after the storing, access to the copy of the file for the application;

writing, based on a write request obtained from the application, to the copy of the file in the temporary storage device to obtain an updated copy of the file;

deleting the temporary storage device in response to generation of a second FBB, wherein the second FBB corresponds to the updated copy of the file;

prior to obtaining the file request:

obtaining, by the FBB metadata file manager, a FBB mount request for a FBB mount of the FBB from the application, wherein the application is executing in a production host environment;

in response to the FBB mount request:

identifying the FBB in a backup storage system;

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

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

storing a FBB virtual file system in the production host environment using the attributes of the storage location;

enabling access to the FBB virtual file system by the application, wherein enabling access to the FBB virtual file system comprises:

obtaining a read request for data in the file system data from the application;

identifying, using the FBB virtual file system, a file path based on the storage of the file system data in the backup storage system; and

based on the file path, obtaining the data from the backup storage system; and

providing the data to 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 attributes of the storage location comprise at least one of: a file identifier attribute, a parent file identifier and a container identifier, a file size, a hash value of a file, and an offset of the file.
