QNAP Netbak Replicator is an easy-to-use and VSS-aware backup software, and helps businesses to create complete backups in datacenter and virtualization environments without needing to purchase expensive and complex commercial software. To build a QNAP Snap Agent and VSS Hardware Provider operating environment, all applications (including VSS Service, Requestor, Provider and QNAP Snap Agent) can be deployed with VSS-Aware applications on the same server, and the minimal requirements are only one ES1640dc and one server for it to be operational.
