Method and system of universal server migration

1. A computer-implemented method for server migration comprising:

with an agent running inside a server, capturing a server image of the server, wherein the server image is independent of a source-compute infrastructure, and wherein the server image comprises a partition table metadata of all of a set of disks and of a set of allocated data blocks of all of a set of filesystems inside the server;

transferring the server image to a dedupe store, wherein the dedupe store implements an inline dedupe of an incoming server image, and wherein a data chunk is present in the dedupe store in dedupe preserving manner so that the data chunk is never replicated to dedupe store by another storage node;

transforming a dedupe stream of the server image into a bootable server image on a target compute infrastructure, wherein in the target compute infrastructure comprises a different compute infrastructure than the source compute infrastructure, the server image was captured from, and wherein the transformation of the dedupe stream is dependent on the target compute infrastructure;

generating a recovery set of disks on the target compute infrastructure; and

creating a recover-process server on the target compute infrastructure using a recovery set of disks.

2. The computer-implemented method of claim 1 , wherein the server image is of a physical-infrastructure server, a virtual-infrastructure server, a hyper-converged storage environment server or a cloud-environment server.

3. A computer-implemented method for server migration comprising:

spawning a recovery agent in a target compute infrastructure;

creating a recovery set of disks;

attaching the recovery set of disks to the recovery agent;

providing a dedupe store, wherein the dedupe store provides a source-server image stream, wherein the source-server image is made bootable by injecting a boot loader and a device driver-into the source-server image that is recovered from the recovery set of disks;

fetching a server image stream from the dedupe store, wherein the dedupe store implements an inline dedupe of an incoming server image, and wherein a data chunk is present in the dedupe store in dedupe preserving manner so that the data chunk is never replicated to dedupe store by another storage node;

writing the server image stream onto the recovery set of disks, wherein the recovery set of disks comprises a replica of the source-server image stream;

with the recovery set of disks, recreating a source server in the target compute infrastructure, wherein in the target compute infrastructure comprises a different compute infrastructure than the server the server image was captured from; and

deleting the recovery agent from the target compute infrastructure.

4. The computer-implemented method of claim 3 , wherein the target compute infrastructure is of a physical-infrastructure, a virtual-infrastructure a hyper-converged storage environment or a cloud environment.

5. The computer-implemented method of claim 3 , wherein to recover a Linux server, Linux recovery agent is created and to recover a Windows server, Windows recovery agent is created.

6. A computer-implemented method for server migration comprising:

spawning a recovery agent in a target compute infrastructure;

creating a recovery set of disks compatible with the target compute infrastructure;

attaching the recovery set of disks to the recovery agent;

providing a dedupe store, wherein the dedupe store provides a source-server image stream, wherein the source-server image is made bootable by injecting a boot loader and a device driver into the source-server image that is recovered from the recovery set of disks, wherein the dedupe store implements an inline dedupe of an incoming server image, and wherein a data chunk is present in the dedupe store in dedupe preserving manner so that the data chunk is never replicated to dedupe store by another storage node;

fetching a server image stream from the dedupe store;

writing the server image stream onto the recovery set of disks, wherein the recovery set of disks comprises a replica of the source-server image stream;

with the recovery set of disks, recreating a source server in the target compute infrastructure, wherein the transformation of the dedupe stream is dependent on the target compute infrastructure; and

deleting the recovery agent from the target compute infrastructure.
