About Virtual Copy Management
HP 3PAR Recovery Manager for Microsoft Hyper-V features an essential Virtual Copy management tool with enhanced recovery commands that allows you to create and restore application consistent Virtual Copies of running Hyper-V Virtual Machines (VMs). When creating a VM Virtual Copy, Recovery Manager for Microsoft Hyper-V identifies all the underlying HP 3PAR volumes and creates Virtual Copies simultaneously for all volumes to ensure consistency. Recovery Manager for Microsoft Hyper-V manages the set of Virtual Copies as a single entity.
NOTE: HP 3PAR Recovery Manager for Microsoft Hyper-V requires a license. In addition, specific licenses are required for HP 3PAR Virtual Copy and HP 3PAR Virtual Lock when performing Virtual Copy operations and setting volume retention policies.
Virtual Copy Data Consistency
You can create application consistent Virtual Copies of Hyper-V Virtual Machines with Microsoft VSS technology and HP 3PAR VSS Provider.
When a VSS aware VM Virtual Copy is created, the VM is put into a saved state during the Virtual Copy creation operation. Simultaneously, both VSS and HP 3PAR VSS Provider automatically creates HP 3PAR Virtual Copies of the underlying LUNs and the VM returns to the previous state during the operation. Recovery Manager for Microsoft Hyper-V then saves any details of the Virtual Copy, along with VSS backup document, for browsing and restoring purposes.
Application consistency is provided for HP 3PAR snapshots of Virtual Machines for data compatibility with supported applications. Recovery Manager for Microsoft Hyper-V supports VSS Child VM Snapshots and provides crash consistent backups through using saved state method.
NOTE: The current version of HP 3PAR Recovery Manager for Microsoft Hyper-V supports system crash, VM and application consistent Virtual Copies. Application consistency is provided for HP 3PAR snapshots of Virtual Machines for data compatibility with supported applications. Recovery Manager for Microsoft Hyper-V supports only VSS Child VM Snapshots.
Virtual Copy Policy
Recovery Manager for Microsoft Hyper-V provides the ability to create Virtual Copy policies for VMs. Only a single policy is permitted for every Virtual Machine and the policies exist independently of the virtual disks the VM is using.
