About boot servers
Boot servers provide the environment that is required to rebuild a protected client, including system recovery needed resources such as shared resource trees (SRT). Boot servers also provide the resources that are used to boot the client system when it performs a network boot before restore.
This known in the NetBackup-BMR language as an SRT or Shared Resource Tree, needs to be created and hosted according to the peculiar requirements of a host's operating system and that of NetBackup-BMR as well. An SRT is a collection of OS files, NetBackup Client Software, and other required software like the Veritas Volume Manager. An SRT is NOT an image of the client and a single SRT can be used for recovering multiple clients. Many of the operations required to be carried out for creation and modification of an SRT are dependent on the target host's operating system. Hence, NetBackup-BMR needs a Boot Server of the same operating system as that of the hosts that are to be recovered.
Boot server software is installed from the NetBackup installation media.
The general deployment including the BMR Boot Server appears as follows:
