Most organizations run business-critical applications, such as Microsoft Exchange, Microsoft SQL Server, or Microsoft Active Directory, on their virtual infrastructure.
In this way, backups of your VMware virtual machines will also include configuration settings, along with all the guest operating system files, enabling VMware VMs to restore exactly the same as they were at the time their backups were made. However, the best way to backup VMware VMs is to utilize an agentless VM backup solution that works at the host or vCenter level to create image-based virtual machine backups. Thus, if there is a need to recover a VMware VM, you will have to create a new virtual machine, load the agent, and restore files. Additionally, configuration settings that make up a crucial part of a properly functioning virtual machine, may not be captured by an agent. Installing and managing guest operating system agents can be time-consuming. Many legacy backup solutions require the use of in-guest agents to perform backups of virtual machines. So, never use snapshots instead of backups! Create Image-based, Application-aware VM Backups
In contrast, using backups provides an autonomous way to preserve and restore your data, without relying on either the physical infrastructure or underlying virtual disks. Thus, if any disk in the chain is corrupted, the whole chain becomes corrupt. VMware snapshots work in a âchainâ, meaning that they require and rely on the base VMDK disks and any other delta disks in place to reflect the current virtual machine state. Snapshots can be useful in development environments providing a quick rollback mechanism to test processes, patches, settings, etc. They are temporary restore points in time that allow for quickly reverting an entire virtual machine, including its settings, to its previous state at a specific point in time. Snapshots are not backups, and VMware does not support them in this capacity. However, this can prove to be a disastrous approach, as VMware snapshots should never be utilized as backups. Many have mistakenly made the decision to rely on snapshots of their VMware virtual machines as a type of backup.
