Disclosed herein are systems and method for backing up data in a load-balanced clustered environment. A clustered resource to be backed up is selected, wherein the clustered resource is stored on a common storage system and operated on by a cluster-aware application executing on at least a first node and a second node of a computing cluster. A load-balanced application may migrate the clustered resource from the first node with a high-load consumption to the second node with low-load consumption. A list of changes made by both nodes are received and merged. A backup agent then generates a consistent incremental backup using data retrieved from the common storage system according to the merged list of changes to the clustered resource.

System and method for backing up data in a load-balanced clustered environment

Disclosed herein are systems and method for backing up data in a clustered environment. A clustered resource to be backed up is selected, wherein the clustered resource is stored on a common storage system and operated on by a cluster-aware application executing on two or more nodes of a computing cluster. A first backup agent executing on a first node of the computing cluster may determine a list of changes to the clustered resource and may receive at least one list of changes to the clustered resource that are tracked by peer backup agents executing on other nodes of the computing cluster. The first backup agent may merge the lists of changes to the clustered resource, and may generate a consistent incremental backup using data retrieved from the common storage system according to the merged lists of changes to the clustered resource.
