The choice of suitable backup solution for an infrastructure depends on what you actually need to protect—configurations, data, VM, applications, and so on. Depending on that, backup solutions can be categorized as follows:

• Backup with agent: This solution is intended for the protection of a physical environment or specific configurations like VM cluster. Vendors like Arcserve or Veritas Backup Exec provide this solution type.
• Native backup for VMware: This is specifically developed for virtualized environments, and is the recommended solution for a virtualized environment because it takes the benefits of vSphere features (for example, snapshots technology). Veeam, Nakivo, Altaro,Vembu, HPE are some vendors that provide backup solutions for virtual infrastructure.
• Hyper-scale backup: Vendors like Rubrik or Cohesity provide ready-to-use backup solutions based on appliances installed in the infrastructure.

Let's discuss the protection of the infrastructure components and the tools used to guarantee maximum availability.
