Goals & Objectives


1- Help you establish a stronger last line of defense for 52X0 appliances DR procedures.

2- Define, what is possible, what is not possible and where to go for more help when it comes to a 52X0 series appliance disaster recovery procedures.

3- Recovery procedures from OST disk devices are all the same with a minor NBU command option difference.

With OpenStorage, NetBackup sees disk as disk and

knows about the advanced capabilities

NetBackup OpenStorage provides

tighter integration,

richer features, better solution

Lifecycle Polices control

the replication from

Alabama Domain to

Colorado Domain and

once the image is

automatically imported by

Policy, the Colorado

Domain copy is managed

by that domain

AIR “Import” is

a) Immediate

and

b) Optimized

(fast) operation

Which one to use? AIR or Opt Dup


1- When it comes to protecting NB clients data, configure A.I.R across your

sites.

2- When it comes to protecting NB catalog of a Master appliance, configure optimized duplication across your sites.

3- When it comes to protecting 52X0 appliances configured as media servers, no NetBackup catalog recovery is required on the Media server appliances during DR.

Master appliance Recovery at Production Site


Customer Environment Note1: Appliance

setup so that the Hot-Catalog backups are

written to an Appliance Storage Server

device and then the image is duplicated to

DR remote location via an SLP

configuration.

How To Read NB Catalog DR File


DR_MEDIA_REC 2 0 0 nb5220dc 2 1 0 0 0 0 0 0 6 35 0 1353982384 @aaaak 1;PureDisk;NB5020DR;NB5020DRDP;PureDiskVolume;0 *

The names of the storage server and disk

pool that will be created in next steps need

to match the production environment. If

there are any questions of what these

names were the DR file can be used to

identify those names.

From this DR file the following items are pointed out:

Storage server type = PureDisk

Storage Server name = NB5020DR

Disk pool name = NB5020DRDP

Procedures for Master Appliance Server Recovery At Local Production Site (Applicable for Any OpenStorage Target)


1) Configure the role of Master Appliance 2) Configure the role of Recovery Media Server 3) Configure Recovery Storage Server 4) Configure a Disk Pool on Recovery Storage Server 5) Configure a DSTU 6) Run nbcatsync to synchronize DR file 7) Tune NetBackup for faster recovery (Buffer Files) 8) Run bprecover

Glossary

Recovery Media Server = 5220 Appliance that holds Catalog backup

Recovery Storage Server = 5220 Appliance that holds Catalog backup

FQDN = Fully Qualified Domain Name

nbcatsync = Reconciles the disk media ID information held in the meta-data of the NetBackup

image database with the disk media ID information found in the NetBackup EMM database.

bprecover = Recovers selected NetBackup related catalogs

Procedures for Master Appliance Server Recovery at Local Production Site


1. Configure the role of Master Appliance using CLISH Login to the appliance as admin and run the following command Main_Menu>Appliance>Master

2. Configure the role of Recovery Media Server using CLISH Login to the master server appliance and run the following command: Main_Menu>Appliance>Add <media server appliance name>

The above command will add the media server appliance as SERVER in bp.conf file & performs below EMM command on the master server nbemmcmd -addhost -machinename XXX -machinetype media -masterserver XXX -netbackupversion 7.5.0.4 -operatingsystem linux http://www.symantec.com/docs/TECH163230 is available for more information.

http://www.symantec.com/docs/TECH163230


3. Configure Recovery Storage Server (using the same name as in production)

Procedures for Master Appliance Server Recovery At Local Production Site

NB CLI ‘s - NB appliances

nbdevconfig -creatests --storage_server nb5220 -stype PureDisk -media_server nb5220

tpconfig -add -stype PureDisk -storage_server abc-01 -sts_user_id root -password root

For 3rd party OST, make sure OST plug-in has been installed and configured

nbdevconfig -creatests -st 9 -storage_server SSS -stype DataDomain -media_server XXX tpconfig -add -storage_server SSS -stype DataDomain -sts_user_id boostuser -password cccc


4. Create the Disk Pool on Recovery Storage Server (using the disk pool wizard and the same name as in production)


5. Configure DSTU

16

6. Run nbcatsync to synchronize the disaster recovery file to the new disk pool


nbcatsync -sync_dr_file /tmp/DR/NBU_Catalog_1358360205_FULL -copy 1 –dryrun

nbcatsync -sync_dr_file /tmp/DR/NBU_Catalog_1358360205_FULL -copy 1


17








7. Tune NetBackup for faster recovery

These touch files will be in /usr/openv/netbackup/db/config

echo 262144 > SIZE_DATA_BUFFERS

echo 256 > NUMBER_DATA_BUFFERS

echo 1048576 > SIZE_DATA_BUFFERS_DISK

echo 512 > NUMBER_DATA_BUFFERS_DISK

For more information, please study

“Symantec NetBackup™ Backup Planning and Performance Tuning Guide”


8. Run bprecover


NB CLI: /usr/openv/netbackup/bin/admincmd/bprecover –wizard

Must monitor to ensure that the Green line

isn’t growing faster than the red line. In this

case, duplications are falling behind

NetBackup Appliances DR Best Practices

25

Document All Appliance Recovery Procedures (Site Specific Step–By–Step)

Re-visit Recovery Point Objectives (RPOs) and Recovery Time Objectives

(RTOs) to ensure recovery per real business requirements

OpsCenter is your friend. Use it to monitor progress of SLPs.

Configure IPMI

Enable Call Home

Store NB Catalog DR File Off-Site

Create Checkpoint Before Applying Maintenance Patches


26

In the past disaster recovery could be overwhelming, but with the current capabilities of NetBackup and our appliances, this has been greatly simplified.
