Hyper-V is an application provided by Microsoft for establishing Virtual environment. Under Virtualization, multiple Operating Systems are installed on physical machine known as host and one can gain access to these operating systems by connecting via guest machines. The process of implementing solutions for protecting Hyper-V environment to mitigate the risk of disruptive events is known as disaster recovery for Hyper-V Environment.

Measures for Successful Disaster Recovery Planning

Hyper-V recovery plan can be used to ensure uninterrupted business mobility in case of issues like: server breakdown, human errors, or virus assaults. Disaster recovery of VHD should be mapped keeping in mind the existing business requirements. The following measures should be taken care of while planning out disaster recovery module:

1. During setup phase, configuring the effective server settings is of prime focus as it needs to be at remote location.
2. Adequate physical resources should be available on site i.e., technical engineers for administrating server environment and monitoring it while live processing.
3. Network configuration is one of the critical components for setting up HADR i.e., Highly Available Disaster Recovery.
4. Multiple networks have to be administered with split subnets. One network is required for local cluster communications and another one for production program networking.
5. The last step includes time to time scheduling of data storage replication and virtual machine once the production goes live.

Despite implementing powerful plans for managing disaster recovery for Hyper-V Virtual environment, the stored data under Hyper-V virtual environment can be vanished due to human errors or system failures. The solution to recover data from corruption is suggested in next segment.

Solution for Recovering Corrupted VHD Files

The files saved on virtual machine can get corrupted while dismounting the virtual data from Server environment. The files created under virtualization environment provided by Hyper-V are saved in VHD format. The VHD files can also get damaged while creating, deleting or formatting a partition on virtual machine. Such damage can be recovered by utilizing commercial Hyper-V disaster recovery for Windows software solution which can also be taken as a disaster recovery solution for VHD files damaged or corrupted with some probable reason. Some of the effective features of the software are as under:

• It offers multiple scanning modes such as Quick, Advance and Raw Scanning.
• It recovers healthy data from corrupt or even permanently deleted VHD files.
• The recovered data is stored in respective file formats, i.e., .doc, .pdf, etc.
• Effectively removes error messages from corrupted VHD files.
