There are several possible ways to do it. Many have mistakenly made the decision to rely on snapshots of their VMware virtual machines as a type of backup. However, this can prove to be a disastrous approach, as VMware snapshots should never be utilized as backups. Some of the ways to do backups are very expensive.
Personally I like NAKIVO VMware Backup as it eliminates the need to track every change in your infrastructure and manually manage basic data protection tasks. And the price is really great comparing with the famous competitors.
