How to backup hyperconverged infrastructure

Enterprises running hypervisors on hyper-converged infrastructure (HCI) systems typically have backup options available to them that are not available to those running on generic hardware. Such customers may also have additional backup challenges depending on the HCI vendor and hypervisor they have chosen. Let’s take a look.

Traditional hypervisor backup

When backing up physical servers you might run a full backup on all of them at one time, and that’s fine. It’s an entirely different situation if all of those servers are actually virtual machines sharing the same physical server. Even running several full-file incremental backups (backing up the entire file even if only one byte has changed) at the same time can significantly affect the performance of your hypervisor. That’s why most customers using server-virtualization products such as VMware or Hyper-V have switched to more hypervisor-friendly methods.
