Similar to traditional operating systems, VMs require periodic or continuous backing. While the two processes do hold some likeness, there are some factors that need special considerations. So, before you run VMware backup software, here are some factors you might want to consider:
1. Backing Up Virtual Disks or OS Images
The .VMDK, .VHD or .VHDX files exist on the storage that is connected to the hypervisor. It holds within it all the essential information and data of a virtual hard disk, that is easily accessible via a specific guest operating system. In order to backup the system, you have two options: to either run an agent in the guest OS or back up single files through the hypervisor.
2. Keep An Eye Out For I/O Storms
If you choose to install a standard backup agent in each VM, you may have to proceed with caution. When using a standard backup agent, you should manually manage the beginning and end time of each backup. This is because of limited bandwidth. Let’s assume you’re operating in conditions where you do not have access to abundant bandwidth. A simultaneous backup may result in slowing down of the overall system. A backup application that is hypervisor-aware is designed to automatically control backups to prevent a slowdown.
3. Opt For Backup Agents That Support The Hypervisor
In the recent past, VMware and Microsoft have made special allowances to address common concerns surrounding the backup of these two systems. This has been a tremendous contribution for managed service providers who now have the tools to effectively manage backing systems. The backup software for the systems that are now developed by companies are customized and especially designed to meet the specifications of certain hypervisors. So, not only are I/O storms managed, but the software creates snapshots using storage virtual disk files, enhancing the security and reliability of the data.
