Catalog Recovery Procedure for the Loss of an Entire Catalog

You should create a detailed disaster recovery plan to follow should 
it become necessary to restore your organization's data in the event 
of a disaster.  A checklist of required tasks can be a tremendous tool 
in assisting associates in triage.  For example, after the facility is 
safe for data to be restored, the power and data infrastructure need 
to be verified.  When these tasks are completed, the following 
scenarios will help to quickly restore the NetBackup environment, and 
in turn, restore applications and data.

Disaster Recovery Procedure using the DR Package file and DR Image File

In the event of a catastrophic failure, use the following procedure to 
rebuild the previous NetBackup environment.

Important Notes:
- If new hardware is required, make sure that the devices contain 
		drives capable of reading the media and that the drive controllers are 
		capable of mounting the drives.
- Keep the passphrase associated with the DR Package file handy. 
		This passphrase is set before the catalog backup policy configuration 
		using the NetBackup Administration Console or the nbseccmd command.
- If this catalog backup is encrypted using a key from a Key Management Server, 
  ensure that the Key Management Server is online before doing any of the following steps.

	1. Install NetBackup.
    a. The installation procedure prompts you to confirm if this is a DR 
							scenario.
						i. On the UNIX installer, you can see a prompt as "Do you want to 
									do a disaster recovery on this master server? [y,n] (y)". 
									Select "y"
      ii. On the Windows installer click the 
										"Disaster Recovery Master Server" button.
    b. The installation procedure prompts you for the master server’s DR 
							Package 
							(refer to the /dr/nbu_dr_file/cat_backup_1438271286_INCR.drpkg 
							mentioned earlier).
       Make sure that the Master Server can access the attached DR package 
							file.
    c. Type the passphrase associated with the Master Server’s DR Package, 
							when prompted.
      i. The installer validates the DR package using that passphrase
      ii. In case of errors in validation, the installer aborts the 
										operation. To work around the issue, refer to the following 
										article: http://www.veritas.com/docs/000125933

	2. Configure the devices necessary to read the media listed above.
	3. Inventory the media.
	4. Make sure that the master server can access the attached DR image file.
	5. Start the NetBackup Recovery Wizard from the NetBackup Administration
	   Console.  Or, start the wizard from a command line by entering
		  bprecover -wizard.

WARNING: CRLs are not backed as part of the DR package backup. 
Refer to the following article to manually add the CRLs:
https://www.veritas.com/support/en_US/article.100044250


Disaster Recovery Procedure without the DR Image File
NOTE: ONLY ATTEMPT THIS AS A LAST RESORT If you do not have the 
attachment included with this email, use the following instructions to 
recover your catalog. (If using OpenStorage disk pools, refer to the 
Shared Storage Guide to configure the disk pools instead of step 2 and 
3 below ):

	1.  Install NetBackup.
	2.  Configure the devices necessary to read the media listed above.
	3.  Inventory the media.
	4.  Run
		    To recover from copy 1:
		    bpimport -create_db_info -stype AdvancedDisk -dp dp-advdisk
      -dv /storage/advdisk
	5.  Run:  
		   cat_export -client client1.example.com
	6.  Go to the following directory to find the DR image file
	    cat_backup_1438271286_INCR:
	    /usr/openv/netbackup/db.export/images/master.example.com/1438000000
	7.  Open cat_backup_1438271286_INCR file and find the BACKUP_ID
	    (for example: master.example.com_1438271286).
	8.  Run:  
		   bpimport [-server name] -backupid master.example.com_1438271286
	9.  Run:
		   bprestore -T -w [-L progress_log] -C master.example.com -t 35 
     -p cat_backup -X -s 1438271286 -e 1438271286 /
	10. Run the BAR user interface to restore the remaining image database 
	    if the DR image is a result of an incremental backup.
	11. To recover the NetBackup relational database, run:
		   bprecover -r -nbdb
	12. Stop and Start NetBackup.
	13. Configure the devices if any device has changed since the last
     backup.
	14. To make sure the volume information is updated, inventory the
     media to update the NetBackup database.
