The choice of the suitable backup solution for an infrastructure depends on what you need to protect—configurations, data, VM, applications, or a complete system state.

Depending on that, backup solutions can be categorized as follows:

• Backup with an agent: This solution is intended for the protection of a physical environment or specific configurations such as a VM cluster. Vendors such as Arcserve and Veritas Backup Exec provide this solution type.
• Native backup for VMware: This was developed explicitly 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, and HPE are some vendors that provide backup solutions for virtual infrastructure.
• Hyper-scale backup: Vendors such as Rubrik and Cohesity provide ready-to-use backup solutions based on appliances installed in the infrastructure.

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