Use sp_addserver to add additional Backup Servers:
sp_addserver instance_name_BS, NULL, instance_name
For example, this adds the cookie_BS entry to sysservers:
sp_addserver cookie_BS, NULL, cookie
You must insert interfaces file entries for each of the Backup Servers before you can start them. See Chapter 5, “Setting Up Communications Across the Network,” in the Configuration Guide for information about editing the interfaces file.
