Abstract
Described is a system for distributing multiple phases of a deduplication processing amongst of set of nodes. The system may perform a load-balancing in configurations where multiple generations of backup data are redirected to the same host node, and thus, require the host node to perform certain storage processes such as writing new backup data to its associated physical storage. Accordingly, the system may perform an initial (or first phase) processing on a first node that is selected based on resource usage or classification (e.g. metadata storing node). The system may then perform a subsequent (or second phase) processing on a second, or host node, that is selected based on the node already storing previous generations of the backup data. Accordingly, the system still redirects processing to a host node, but provides the ability to delegate certain deduplication operations to additional nodes.
