LEVERAGING CONTINUOUS REPLICATION TO COPY SNAPSHOT BACKUP IMAGE
First Claim
1. An Information Handling System (IHS), comprising:
- a processor; and
a memory coupled to the processor, the memory comprising program instructions stored thereon that, upon execution by the processor, cause the IHS to;
store enterprise data in a primary volume;
store snapshot data referring to the enterprise data in the primary volume;
receive a command to backup the snapshot data separately from the enterprise data;
create a virtual volume in response to the command, wherein the virtual volume includes pointers to the snapshot data; and
backup the snapshot data via replication of the virtual volume onto a snapshot backup image volume.

Abstract
Systems, methods and devices provide efficient data protection by creating backup images of snapshots using the replication capabilities of the data protection system. The snapshots are point-in-time representation of a data set, where the snapshots allows recoverable states of the data set without having to make a complete copy. A snapshot to be backed up is stored in a primary volume. A virtual volume is created, the virtual volume comprising references, such as pointers, to the snapshot data stored in the primary volume. The snapshot data referenced by the virtual volume is then replicated using the replication capabilities of the data protection system. In this manner, the replication of the snapshot does not burden the primary volume that is hosting the snapshot storage.
