Abstract

Techniques to back up a cluster shared volume (CSV) are disclosed. In various embodiments, a snapshot of the cluster shared volume is stored persistently on the cluster shared volume itself. A task to back up a corresponding assigned portion of the snapshot is assigned to each of one or more cluster servers available to participate in backing up the cluster shared volume. The cluster servers have shared access to the snapshot as stored on the cluster shared volume, and each is configured to perform the task assigned to it in parallel with any other cluster servers assigned to back up other portions of the same cluster shared volume snapshot. The respective assigned tasks are monitored to completion.
