About shared resource trees
A shared resource tree (SRT) is BMR system recovery critical software which is a collection of the following:
Operating system files
NetBackup client software
Programs that format drives, create partitions, rebuild file systems, and restore the original files using the NetBackup client software
An SRT also provides the resources that are needed to boot the client system and begin the restore process.
The software in an SRT is not installed permanently on the protected system. Its purpose is to bring the protected system to a state from which the original files can be restored.
Note the following:
For UNIX and Linux systems: Each client type and operating system version requires its own SRT. For example, Solaris 11 requires a Solaris 11 SRT, AIX 7.1 TL3 requires an AIX 7.1 TL3 SRT, and so on.
For Windows systems: A single SRT can restore all Windows versions of the same architecture. For example, 64-bit Windows SRT can restore Windows 2008/2008R2 64-bit clients.
For UNIX and Linux systems, you create SRTs on boot servers of the same operating system. The boot server must run the same version or a later version of the operating system that is installed in the SRT. For example, a Solaris 11 SRT must reside on a Solaris 11 or later boot server. For Windows systems, any version of Windows can host the SRT.
For more information about supported operating systems for clients, SRTs, and boot servers, see the NetBackup Release Notes.
During a restore, a client accesses the SRT from a boot server over a network, or on a CD or DVD. Although SRTs reside on boot servers, you can copy an SRT to CD media or DVD media, boot the client from that media, then access the SRT on that media. If you are using a BMR Media, you do not require the boot server during recovery.
Depending on the operating system for which an SRT is created, the SRT size requirement can vary from 100 MB to 1 GB of disk space.
For more information about disk space requirements, see the NetBackup Release Notes.
