FalconStor Software Inc. introduced Tuesday a new version of its iSCSI Storage Server software, built on Microsoft Windows Storage Server 2003, and intended for disaster recovery, disk-based backup and rapid restore applications. The iSCSI Storage Server sports an IP-based delta replication of an application host's mission-critical data, from a primary site to a remote site over IP in a peer-to-peer or many-to-one configuration, based on policy. The iSCSI Storage Server also protects host-based systems and user workstations via replication of local files and directories, as well as mirroring an entire local disk to an iSCSI server-managed disk for automated off-site data storage backup and disaster recovery, FalconStor said.
