In the last few years, the hypervisor vendor VMware has made great strides in providing a simple and consistent way to protect application data stored on virtual servers. HP Data Protector, for example, is a software package that works seamlessly with the VMware platform to enable rapid and reliable security of the virtual servers users create with VMware.
One challenge HP Data Protector faces, however, is the circumstance of enterprise customers wanting to deploy several different versions of hypervisor technology. This happens because in many organizations, various needs can be best met using a specific hypervisor platform. For example, medium and large enterprises frequently prefer to deploy Citrix XenServer in order to provide virtualized desktops to staff working at corporate headquarters or large branch offices. However, alternate hypervisor software is sometimes preferable in remote offices; Microsoft's Hyper-V is often a popular choice in such situations. VMware is considered by many enterprises to be the best choice specifically for virtualization of a data center.
Any enterprise using managed services to help them deploy multiple hypervisors must be sure they have IT solutions in place to manage not just backup functions, but also recovery across multiple platforms. Complete protection is a further challenge in virtualized environments because with many platforms, creating a new VM (virtual machine) can be performed by a knowledgeable end user, but that VM may not be automatically included in existing backup and recovery routines. Keeping backup administrators "in the loop" is one of the challenges inherent to the new virtualized world of business IT infrastructure.
