ABSTRACT:
A composite storage server employs a plurality of distributed storage sites including a mount site, a source copy site and one or more copy target sites for executing a storage of volume data within the composite storage server. In operation, an immediate copy target site receives a communication of a source copy complete message from the mount site, the source copy complete message being indicative of the source copy site having a complete copy of the volume data. Based on the source copy complete message, the immediate copy target site pulls the volume data from a peer distributed storage site having a complete copy of the volume data (e.g., the source copy site, the mount site or another copy target site).
