Dell PowerVault DL2000 - Manual (Page 30)

Disaster Recovery Planning Using IDR
NOTE: This section applies to DL appliances running Backup Exec versions prior to Backup Exec 2012. For disaster
recovery planning for Backup Exec 2012 and later see the topic “Disaster Recovery Planning Using SDR”.
The primary role of the PowerVault DL Backup to Disk Appliance is to protect the files, databases, and critical
applications of other computer systems. Steps must be taken to ensure that the appliance can be recovered should a
disaster strike. When a hardware failure, software error, or a natural disaster affects the appliance, you must reinstall
the following:
• The appliance operating system
• Backup Exec
• Appliance updates
• Other applications
If the Backup Exec database is lost or corrupted, you must manually recreate backup jobs, policies, and schedules. You
cannot run backup and recovery jobs until the appliance is fully operational. To adequately prepare the appliance, you
must perform the following:
• Configure Backup Exec Intelligent Disaster Recovery (IDR) on the appliance.
• Schedule a full backup of the appliance to run on a regular basis.
• Schedule a backup of the optional deduplication storage folder (DSF) to run on a regular basis.
• Maintain the Backup Exec and optional deduplication services passwords.
Backup Exec IDR Option
Backup Exec IDR is a bare metal recovery solution that allows you to recover the appliance in the event of a complete
catastrophic software or hardware failure. IDR restores the appliance system software to the state of the last full
backup set. This includes all files and software installed on the appliance. For more information on the Backup Exec IDR
option, see the
Symantec Backup Exec Administrator's Guide at symantec.com.
IDR Restrictions And Limitations
IDR requires Backup to Disk Folders to backup the critical system files and system state. If the appliance configuration
contains a DSF and no Backup to Disk Folders, you cannot use IDR to recover the operating system. See the topic
“Recovery Solution Map” and follow the non-IDR recovery steps based on the failure type to recover the appliance. See
the
Symantec Backup Exec Administrator’s Guide at symantec.com for additional information on Backup Exec
Deduplication option and the DSF.
Preparing the System To Use IDR
To configure IDR on the appliance, follow the steps below:
1. Prior to configuring IDR, ensure that all internal and external storage has been configured including the DSF if the
Backup Exec Deduplication option is enabled and licensed.
2. Navigate to the Home view in Backup Exec and select Configure Intelligent Disaster Recovery in the Getting
Started section.
3. Select an alternative location to store the disaster recovery *.DR file.
Ensure that the location does not reside on any of the appliance's internal physical disks.
