As organizations consolidate more virtual machines on fewer servers, and IT computing infrastructure is expected to support 24x7 operations, data protection and recovery becomes a greater challenge for IT managers. With nightly backup windows shrinking and more application data sets sharing fewer physical servers, both bandwidth and computing cycles require existing backup methods to be augmented with new technologies. Virtual server and hypervisor-based snapshotting and replication tools are available today, but they can consume far too much of the physical servers’ resources and provide less than optimal storage utilization. In both scenarios, virtual machine recovery is often slow and sometimes unreliable.
