Which agent do I need?

Selecting an agent depends on what you are going to back up. The table below summarizes the information, to help you decide.

In Windows, Agent for Exchange, Agent for SQL, Agent for Active Directory, and Agent for Oracle require that Agent for Windows is also installed. Thus, if you install, for example, Agent for SQL, you also will be able to back up the entire machine where the agent is installed.

It is recommended to install Agent for Windows when you install also Agent for VMware (Windows) and Agent for Hyper-V.

In Linux, Agent for Oracle and Agent for Virtuozzo require that Agent for Linux (64-bit) is also installed. These three agents share one installer.

*During the installation, Agent for Exchange checks for enough free space on the machine where it will run. Free space equal to 15 percent of the biggest Exchange database is temporarily needed during a granular recovery.

**If your ESXi uses a SAN attached storage, install the agent on a machine connected to the same SAN. The agent will back up the virtual machines directly from the storage rather than via the ESXi host and LAN. For detailed instructions, refer to "Agent for VMware - LAN-free backup".

***For Virtuozzo 7, only ploop containers are supported. Virtual machines are not supported.

****A virtual machine is considered virtual if it is backed up by an external agent. If an agent is installed in the guest system, the backup and recovery operations are the same as with a physical machine. Nevertheless, if Cyber Protection can identify a virtual machine by using the CPUID instruction, a virtual machine service quota is assigned to it. If you use direct passthrough or another option that masks the CPU manufacturer ID, only service quotas for physical machines can be assigned.
