Server DR protection using BMR
The process of Protecting servers from disaster using BMR occurs in three phases. These phases are
BMR Enabled backup
NetBackup backup policy needs to be BMR-enabled so that during client backup, client system skeleton information is backed up which is required to recover client when DR is intended. This system skeleton info comprises OS details, disk information, volume details, file system information and network information. For details about BMR Backup process, refer chapter Protecting clients.
Recovery Pre-requisites
Setting of restore prerequisite can be done any time prior to DR of client is intended. It is recommended to have this prerequisite little prior to avoid any delay in recovery. During this phase, recovery critical software i.e., share resource tree needs to be prepared on BMR Boot server. This SRT forms a staging environment to do client recovery. Single SRT can be used to recover clients belonging to same operating system family. For details about recovery pre-requisites, refer chapter Setting up restore environments.
Client Recovery
This is the actual client recovery phase, where client computer boots into recovery environment. The client needs to be prepared for recovery by running single command line or single click. BMR supports two recovery methods: Network-based boot and Media-based boot. For details about client recovery process, refer chapter Restoring clients. BMR can also be leveraged in NetBackup's Auto Image Replication setup to recover primary domain host into DR Domain.
