Managing boot media
Boot media is used to boot a client and provide the shared resource tree or the resources to mount a shared resource tree. The boot media contains a small run-time environment that includes a kernel, a RAM file system, libraries, and programs. The client system firmware boots the kernel from the media. This boot media also contains a shared resource tree.
If you use media to boot the client system, you must use BMR to prepare the appropriate boot media. You can prepare boot media at any time before the restore. However, a prerequisite is that the shared resource tree for the protected system must exist.
Boot media is created from the resources that are stored in an SRT.
