3. The method of claim 2 , further comprising:

receiving a notification that the first portion of the video data chunks were de-staged from the secondary storage to the archival storage; and

updating, in response to the notification, the first retention and staging metadata to reflect a new location of the first portion of the video data chunks.

4. The method of claim 1 , further comprising

making a first determination, by the DPU, that all of the video data chunks are in an archival storage; and

in response to the first determination:

obtaining all of the video data chunks from the archival storage;

stitching, by the DPU, the video data chunks to obtain a video file;

transmitting the video file to the archival storage.

5. The method of claim 4 , further comprising:

after transmitting the video file to the archival storage:

making a second determination that a retention period associated with the video file has expired; and

in response to the second determination:

deleting the video file from the archival storage.

6. The method of claim 1 , wherein the video data comprises at least one selected from a group consisted of:

video data obtained from a video camera; and

video data stored in a backup storage.

7. The method of claim 6 , wherein the video camera is connected to the edge device with a local connection and the backup storage is connected to the edge device with a non-local connection.

8. A system for processing video data, comprising:

a backup storage operatively connected to an edge device comprising:

primary storage,

secondary storage, and

archival storage;

a video camera operatively connected to the edge device and configured to generate video data;

the edge device comprising a data processing unit (DPU), wherein the DPU is configured to perform a method, the method comprising:

obtaining the video data;

processing video data to obtain video data chunks and video processing engine outcomes, wherein the video processing engine outcomes are obtained using the video data and one or more data analytics models, and wherein the video processing engine outcomes comprise fraud detection video processing engine outcomes and facial recognition video processing engine outcomes;

generating first retention and staging metadata based on a first portion of the video data chunks and a first video processing engine outcome of the video processing engine outcomes associated with the first portion of the video data chunks, wherein the first retention and staging metadata specifies retention and staging information associated with the first portion of the video data chunks;

generating second retention and staging metadata based on a second portion of the video data chunks and a second video processing engine outcome of the video processing engine outcomes associated with the second portion of the video data chunks, wherein the second retention and staging metadata specifies retention and staging information associated with the second portion of the video data chunks;

associating the first retention and staging metadata with the first portion of the video data chunks and the second retention and staging metadata with the second portion of the video data chunks;

storing the first retention and staging metadata and the first portion of the video data chunks in first appropriate storages based on the first retention and staging metadata; and

storing the second retention and staging metadata and the second portion of the video data chunks in second appropriate storages based on the second retention and staging metadata.

9. The system of claim 8 , wherein obtaining the video data comprises obtaining the video data obtained from the video camera.

10. The system of claim 8 , wherein obtaining the video data comprises obtaining the video data stored in the backup storage.

11. The system of claim 8 , wherein the video camera is operatively connected to the edge device with a local connection and the backup storage is operatively connected to the edge device with a non-local connection.

12. The system of claim 11 , wherein the local connection is a local wireless connection.

13. The system of claim 11 , wherein the local connection is a local wired connection.

14. The system of claim 11 , wherein the non-local connection is a network connection over a wide area network.

15. 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 processing video data, the method comprising:
