vvFrom the Tivoli Storage Manager GUI Backup panel, expand the "Hyper-VVMs" container, and select the virtual machine to back up.You can also enter dsmc backup vm -vmlist=vm1 -vmbackuptype=HyperVFullon the Tivoli Storage Manager command prompt, where vm1 is the name ofthe virtual machine.Important:a. If the virtual machine is not fully VSS-compliant (the operating systemsupports VSS, and all virtual hard drives (VHD) are configured to supportVSS):v The virtual machine that is running pausesv A snapshot is takenv The virtual machine resumesb. If Microsoft clustering is enabled, you might need to set the clusterdisksonlyoption to NO to back up Hyper-V VMs. This action is necessary if any VMfiles or supporting VM files reside on disks that are not clustered.4. Restore a virtual machine:v From the Tivoli Storage Manager GUI Restore panel, expand the Hyper-VVMs container, and select the virtual machine to restore.v You can also enter: dsmc restore vm1 -vmlist=vm1 -vmbackuptype=HyperVFull on the Tivoli Storage Manager command line,where vm1 is the name of the virtual machine.Important: When a restore operation is complete, the existing virtual machineis stopped (if it is running) and all existing files (for example, VHD) aredeleted. When the backup snapshot is restored, all the virtual machines thatexisted when the files were backed up are recreated. This includes any Hyper-Vsnapshots that existed when the files were backed up.You can set up Tivoli Storage Manager scheduled backups on a regular basis (forexample, once a week). Create the schedules as MACRO type schedules with themacro file located in the Tivoli Storage Manager Backup-Archive Client directoryof the Hyper-V machine. The contents have the dsmc command, for example: dsmcbackup vm -vmbackuptype=HyperVFull.Related reference“Backup VM” on page 552“Query VM” on page 610“Restore VM” on page 644“Clusterdisksonly” on page 317Hyper-V backup support limitationsDue to the tight integration of Microsoft Failover Clustering with Cluster SharedVolumes and Hyper-V, the following limitations apply when using Tivoli StorageManager.Microsoft Hyper-V support is provided for the following configurations:v A dedicated Hyper-V system orv A Hyper-V configuration that is part of Microsoft Failover Clustering orv A Hyper-V configuration that is part of Microsoft Failover Clustering withCluster Shared Volumes150 IBM Tivoli Storage Manager for Windows Backup-Archive Clients: Installation and User's Guide
