Virtual server backup is the copying of data stored on a virtual server to ensure complete and comprehensive protection of data to facilitate uninterrupted business operation. Server backups on a virtual machine can be carried out using any one of the many conventional backup software available in the marketplace. These backup software are installed on the virtual machine on which data is installed and the backup copy of the data is made to the pre-specified destination.
This is the most simple and straightforward approach to backup data but has its own certain downsides. It is a resource intensive process and the additional resources needed to execute a backup may put extra burden on the resources of the virtual machine. Additionally, backup license also needs to be acquired for the software needed to make a backup copy of the stored data.
Client-based backups are a common way to backup virtual servers and provide the ability to recover single files. However, recovering the entire virtual machine image for disaster recovery can be a cumbersome process, which can degrade the performance of the virtualised application. It is therefore important to look for a virtual server backup provider that can offer a host of backup solutions without impacting the overall performance.
