Quantum's vmPRO software and appliances are used for protecting virtual machine (VM) data. vmPRO software works with DXi appliances and users' existing backup applications to integrate VM backup and recovery into their existing data protection processes. It auto-discovers VMs and presents a file system view, allowing users to back up VMs or files within VMs without adding VM-specific agents. When data is read through the vmPRO software, inactive data is filtered out, reducing backup volumes by up to 75% and boosting deduplication rates. To support fast recovery, vmPRO software augments traditional backup with a simple VM snapshot utility that creates native-format VM copies on secondary disk, allowing restore at a VM or at a single file level.
