Contrary to the popular belief, Hyper-V does not add layers of complexity to server backup. The Cloud backup application encapsulates the complexities and simplifies the process of Hyper-V backup.
Cloud backup systems take advantage of the snapshot technology that is integral to the Hyper-V server and tweaks it to confer Cloud backup advantages. The technology uses application aware plug-ins and ensures that the snapshot backs up the database and the system memory, so that there is no data loss or inconsistency in the database that is backed up to the Cloud. Further, the snapshot is taken off-site to the Cloud and any loss of local hardware does not result in the loss of the snapshot.
Hyper-V servers can be run at the host level or within a guest operating system. Combinations of the two are frequently used by organizations. If the Hyper-V host or the guests are up and running, the backup process will require the installation and enablement of integration services, the guest operating systems must use volumes that are formatted as NTFS, FAT or FAT-32, the guests use basic disks and Volume Shadow Copy is enabled. The Cloud backup software automatically checks for all these parameters and creates a “catch-all” backup solution that backs up the configuration settings for each virtual machine, virtual hard drives and virtual machine snapshots that may exist on the machine. In the event of disaster, the administrator will be spared the necessity of rebuilding the configurations. The Hyper-V server recovery is comprehensive.
This brings us to a discussion of Hyper-V restoration issues. The Cloud backup technology recognizes that there are many Windows Server backup specific limitations in the restoration of Hyper-V servers. The application works around these issues and allows users’ recover individual snapshots and perform application recovery of the Hyper-V host or guest server or a combination of the two types of Hyper-V deployments with ease. The recovery can be orchestrated on to a same or similar hardware or even completely different hardware environment. This is known as “Bare Metal” recovery. This is because the virtual machine configuration can be recreated from the snapshot along with the content of the server.
Generally, there are no extra licensing fees to contend with for the backup of Hyper-V servers when users subscribe to a Cloud backup service. But, it is recommended to verify this with your Cloud backup service provider before you sign up on the dotted lines.
