A backup agent can back up any file system that is accessible from the operating system where the agent is installed. For example, Agent for Windows can back up and recover an ext4 file system if the corresponding driver is installed in Windows.
The following table summarizes the file systems that can be backed up and recovered (bootable media supports only recovery). The limitations apply to both the agents and bootable media.
