Abstract

Claims (74)

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

obtaining, by a backup agent comprising circuitry, a FBB generation request for a file system at a point in time;

in response to the FBB generation request:

identifying a target backup storage system in which to store the FBB;

identifying a target exposed application programming interface (API) associated with the target backup storage system;

initiating generation of a temporary storage device, wherein initiating the generation of the temporary storage device comprises partitioning a portion of storage of a backup agent;

generating a FBB corresponding to the FBB generation request using the temporary storage device,

wherein the FBB comprises a FBB metadata file,

wherein the FBB is in a common data streaming format (CDSF);

generating an API command based on the FBB and the target exposed API;

initiating storage of the FBB in the target backup storage system using the API command;

deleting the temporary storage device in response to generation of the FBB;

obtaining, by the backup agent, a FBB mount request from a production host environment;

in response to the FBB mount request:

identifying the FBB in the target backup storage system;

obtaining the FBB metadata file;

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

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

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 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.

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

4. 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 comprising circuitry, a FBB generation request for a file system at a point in time;

in response to the FBB generation request:

identifying a target backup storage system in which to store the FBB;

identifying a target exposed application programming interface (API) associated with the target backup storage system;

initiating generation of a temporary storage device, wherein initiating the generation of the temporary storage device comprises partitioning a portion of storage of a backup agent;

generating a FBB corresponding to the FBB generation request using the temporary storage device, wherein the FBB comprises a FBB metadata file, wherein the FBB is in a common data streaming format (CDSF);

generating an API command based on the FBB and the target exposed API;

initiating storage of the FBB in the target backup storage system using the API command;

deleting the temporary storage device in response to generation of the FBB;

obtaining, by the backup agent, a FBB mount request from a production host environment;

in response to the FBB mount request:

identifying the FBB in the target backup storage system;

obtaining the FBB metadata file;

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

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

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.

5. The non-transitory computer readable medium of claim 4 , 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 of a file, and an offset of the file.

6. The non-transitory computer readable medium of claim 4 , wherein the file system data comprises data tags.

7. A system comprising:

a processor; and

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

obtaining, by a backup agent operating on the processor, a FBB generation request for a file system at a point in time;

in response to the FBB generation request:

identifying a target backup storage system in which to store the FBB;

identifying a target exposed application programming interface (API) associated with the target backup storage system;

initiating generation of a temporary storage device, wherein initiating the generation of the temporary storage device comprises partitioning a portion of storage of a backup agent;

generating a FBB corresponding to the FBB generation request using the temporary storage device,

wherein the FBB comprises a FBB metadata file,

wherein the FBB is in a common data streaming format (CDSF);

generating an API command based on the FBB and the target exposed API;

initiating storage of the FBB in the target backup storage system using the API command; and

deleting the temporary storage device in response to generation of the FBB;

obtaining, by the backup agent, a FBB mount request from a production host environment;

in response to the FBB mount request:

identifying the FBB in the target backup storage system;

obtaining the FBB metadata file;

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

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

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.

8. The system of claim 7 , 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 of a file, and an offset of the file.
