• You should perform test backups and restores.
• You MUST have a backup schema & DRP plan to keep your job.
Joe Holbrook, CHPTP XXXXX 2

NETBACKUP OVERVIEW
• Q. What is Veritas Netbackup?
• A. Veritas Netbackup is an enterprise backup and recovery solution that is the industry standard.
• Q. How does Veritas Netbackup help Unix
Admins?
• A. Ensures every file gets backed up and is able to be restored by using cataloging.
Joe Holbrook, CHPTP XXXXX 3

NETBACKUP OVERVIEW
• Netbackup will backup, restore and archive files.
• Uses GNU tar format
• Use TCP to establish communications.
• Performs both FULL and incremental backups

• Netbackup has a collection of “add on” products and agents. None of which were purchased.
Joe Holbrook, CHPTP XXXXX 6

JTAV NETBACKUP FYI
• We currently have an Oracle database.
• The person that specified this configuration did not specify the Netbackup for oracle or nor the oracle database agent to allow “hot or online” backups, advanced recovery and management, etc.
• We will require a “cold” backup increasing downtime.
Joe Holbrook, CHPTP XXXXX 7

Veritas.Com
Joe Holbrook, CHPTP XXXXX 11

Veritas Netbackup DataCenter
• Netbackup automates the backup and archive routines on Valiant and Hood.
• Full backups run weekly on Fridays and
Incremental-Differentials daily.
• Valiant is the “Master” server and the
“Media” server
. (Master being the manager and Media being the controller of media such as tape drives and disks.)
Joe Holbrook, CHPTP XXXXX 12

• We could add more servers to list.
• Just have to add the Netbackup client agents and configure the client backup policy.
• Netbackup uses ports to connect to clients and for processes.
• Netbackup is broken into two subsections.
• Netbackup and Media Manager
Joe Holbrook, CHPTP XXXXX 13

VERITAS PORTS
• Veritas uses ports to communicate over the network. TCP port connections to be exact.
The next page covers the ports used by
Netbackup and the Media Manager.
• The configuration of these is done during the installation of Netbackup.
• These can be found in the /etc/services file.

NETBACKUP Terminology
• The following several slides cover common
NETBACKUP terms and principals to give a brief understanding of terms and principals.
• Review the bibliography for more info.
• Review the documents on www.veritas.com
.
• Review the HELP menu.
Joe Holbrook, CHPTP XXXXX 19

• Archive.
An archive is special backup in Netbackup where it will backup up the file(s) and then delete the file(s) from the local disk.
Joe Holbrook, CHPTP XXXXX 20

• Catalog.
A catalog is a an internal database that contain info about configuration, media, devices, errors, logs, etc.
• Policy.
A policy is a template for backup a single client or a group of clients.
Joe Holbrook, CHPTP XXXXX 21

• Disk image backup
A disk image backup is a bit by by bit backup rather than a file system backup.
• Duplicate image
A duplicate image is a copy of a backup.
• Expiration
Time when a volume is considered unusable
Joe Holbrook, CHPTP XXXXX 22

• Multiplexing.
1.
Netbackup can send multiple concurrent backups from one client or several to a single storage device(tape, disk, NDMP, etc).
2.
Multiplexing is used to reduce backup time.
3.
Multiplexing is done sequentially onto the media.
4.
Multiplexing reduces restore performance.
Joe Holbrook, CHPTP XXXXX 23

•
Why multiplex!
1. Reduce backup times
2. Slow network connections
3. Many short backups (incrementals on small and lightly used file systems)
4. Software compression
Joe Holbrook, CHPTP XXXXX 24

•
Configure Multiplexing
Must be configured in two places (menus)
1. Storage Unit
“Maximum Multiplexing per Drive for
Storage Unit”
Number range 1 – 32
Joe Holbrook, CHPTP XXXXX 25

2. Schedule setting
“Media multiplexing” value
Must be also set for multiplexing to work.
Important
Storage unit and schedule settings must be set. If you set 8 for storage unit and 6 for schedule then the max “multiplexes” will be 6.
Joe Holbrook, CHPTP XXXXX 26

NETBACKUP TERMINOLOGY
• Multistreaming
Multistreaming establishes multiple connections, or threads , from a single system to the backup server. This is useful if you have a large system with multiple I/O devices and large amounts of data that need backing up.
Joe Holbrook, CHPTP XXXXX 27

•
Storage Unit
A Storage Unit is a group of one or more storage devices that are the same type
(disk, tape, etc) and density (DLT, SDLT, etc)
•
There are 4 types of storage units in
Netbackup and for the JTAV project only two can be used currently.
Joe Holbrook, CHPTP XXXXX 28

•
Storage Unit (four types)
1. Media Manager – uses tape robots, standalone drives or optical disk drives that are under the Media Manager control.
2. Disk – A storage unit that is basically a directory on a disk. Unlimited can be set up in Netbackup.
**Notes
Joe Holbrook, CHPTP XXXXX 29

3. NDMP – NDMP is an optional functionality but also requires you have a
NDMP host (NetAPP).
4. Fastrax – another optional functionality and requires an EMC system.
**optional in Veritas means “separately purchased product”
**Note
Joe Holbrook, CHPTP XXXXX 30

• True Image backup - is a snapshot of files done at the directory level at a certain point in time. When a "True Image" backup is restored, the directory restored will be brought to the same state as when it was backed up. Any files or sub-directories that did not exist at the time of backup will be deleted when the restore occurs if it is restored to the same location.
Joe Holbrook, CHPTP XXXXX 31

• Volume group - is a group of volumes that have some common physical location or characteristic, such as being in the same library, at the same offsite location, having the same media density, or the like. There may be more than one group in a location, however, all media in a volume group must be in the same location.
Joe Holbrook, CHPTP XXXXX 32

VERITAS NETBACKUP
• bp.Conf.
The main configuration file for Netbackup is.
/usr/openv/netbackup/bp.conf.
This is true for clients, media and master servers.
The only difference is the types and number of
OPTIONS you can specify and how. Refer to the
Netbackup system administrator guide for UNIX.
Joe Holbrook, CHPTP XXXXX 33

VERITAS NETBACKUP
•
Backup policy.
1. A backup policy is a “template” for backup up clients.
2. Every client must be in at least one policy but can be in many policies.
3. Easier to divide clients into group by the requirements. Then create policy for each group of clients.
Joe Holbrook, CHPTP XXXXX 34

VERITAS NETBACKUP
• Backup policies are configured within four tabs of the policy menu
• 1. General attributes determines policy storage units, settings, types of backups, etc
• 2. Schedules specifies when the backup occurs and the type of schedule (automatic or user set)
Joe Holbrook, CHPTP XXXXX 35

VERITAS NETBACKUP
3. File list contains the list of files to be backed up.
You can use the parameter
ALL_LOCAL_DRIVES to backup all of the files and drives.
• Select “cross mountpoints”, true image recovery
& allow Mutiple data streams.
•
Do not select compression (software).
•
Our DLT drives support hardware compression
Joe Holbrook, CHPTP XXXXX 36

VERITAS NETBACKUP
4. Client List is the “clients” that are to be backed up by the policy.
• Example: all UNIX clients use “Standard”
Policy.
• Remember to add the client to /etc/hosts.
You can also use an IP address.
• To install a client you configure the /.rhosts file on the client. **Notes
Joe Holbrook, CHPTP XXXXX 37

VERITAS NETBACKUP
• Catalogs.
A catalog is a an internal database that contains info about configuration, media, devices, errors, logs, etc.
• Catalogs are in “binary” format in NB 4.5.
• Netbackup places the catalog backup in default locations. You can change this.
Joe Holbrook, CHPTP XXXXX 38

VERITAS NETBACKUP
• Netbackup catalogs are important to maintain for recovery purposes. If you lose your server or need to restore to a new machine then the catalog is critical.
•
JTAV servers catalog backups up the following directories.
Media catalog.
/usr/openv/netbackup/db.
Joe Holbrook, CHPTP XXXXX 39

VERITAS NETBACKUP
Volume catalog & device catalog.
/usr/openv/volmgr/database.
Logs & config.
/usr/openv/var.
Joe Holbrook, CHPTP XXXXX 40

VERITAS NETBACKUP
• Reporting
Netbackup has great reporting capability for reporting the management, verification and troubleshooting of Netbackup operations.
• Refer to the Netbackup Systems
Administrator Guide for UNIX Chapter 5, page 195
Joe Holbrook, CHPTP XXXXX 41

• Full – Need to explain (Level 0)
• Cumulative incremental backup is the backup of all files that have changed since the last full backup.
• Differential incremental backup is the backup of all files that have changed since the last backup.
Joe Holbrook, CHPTP XXXXX 42

• Busy file processing is a series of configurations and actions set in the bp.conf
file that can be executed when a file that cannot be read (read-locked) is encountered.
Joe Holbrook, CHPTP XXXXX 43

Reporting
Reports (10 types)
1. Status of backups
2. Client backups
3. Problems
4. All log entries
5. Media list reports
6. Media contents reports
Joe Holbrook, CHPTP XXXXX 44

Reporting
7. Images on media

•
You can select the fields you need by specifying bpdbjobs -report –state –status –class –schedule – client -server
Joe Holbrook, CHPTP XXXXX 46

• Four media states
1. Full
2. Suspended
3. Frozen
4. Imported
Joe Holbrook, CHPTP XXXXX 47

• Full – No more space on Media
Can use it for restore but you can not use it for backup
• Suspended – Cant do nothing.
• Frozen – Put on Hold
Can restore bu
Joe Holbrook, CHPTP XXXXX 48

• Imported - Media was imported (restored) to the NB database.
Joe Holbrook, CHPTP XXXXX 49

Refer to page 424 of the Netbackup system
Administratiojn guide for UNIX
Joe Holbrook, CHPTP XXXXX 57

• Logging allows monitoring of NETBACKUP
• There are 10 logging levels 0 being min, 9 being max.
• Logging default level is 0
• You must create logs in
/usr/openv/netbackup/logs
• Configure bp.Conf logging level by VERBOSE = ?
• ? = The logging level 0 - 9
Joe Holbrook, CHPTP XXXXX 58

• Create Logs by
• Cd /usr/openv/netbackup/logs
• mkdir bpcd
• mkdir bprd
• Etc for each daemon & process
Joe Holbrook, CHPTP XXXXX 59

Daemons can started or stopped by several ways
• initbprd
• bprdreq –terminate
• initbpdbm
• xbpadm
• bpadm
• jnbSA
Joe Holbrook, CHPTP XXXXX 60

•
Netbackup uses a worklist for the flow of automatic backups. (Que)
•
This determines the backup priotity and scheduling of backups
1. The highest priority backup goes first
2. Backup with retention level as tape in drive currently!
3. Most overdue backup
Joe Holbrook, CHPTP XXXXX 61

Display the robot inventory. Do the following process.
Java GUI:
1. Start media and device management.
2. Click on the media manager that hosts the robot you wish to inventory. .
Joe Holbrook, CHPTP XXXXX 62

3 . Select inventory robot from the actions menu.
4. Select the robot on the host you wish to inventory
5. Select show contents of robot
6. Start to obtain an inventory.
Joe Holbrook, CHPTP XXXXX 63

• By the command line
• Note that ACS and TLM type libraries are not managed by NetBackup and you cannot inventory through this method. .
• vmupdate .
• vmcheckxxx -rt robot_type -rn robot_number -list.
Joe Holbrook, CHPTP XXXXX 64

• Tapes for restore (GUI
).
1.
If you are using the java GUI, start the restore of the file, files, directories, etc .
2.
Then click "preview media required".
You can also perform the restore (either via the GUI or command line), and have messages written to a log file. The beginning of the log will contain a list of tapes needed for the restore.
.
Joe Holbrook, CHPTP XXXXX 65

• Tapes for Restore(command line)
Or you can avoid the GUI (and avoid having to kick off a restore) with the bpimagelist command. Let's assume you want to restore from a backup of CLIENTA that happened on August 1st.
(these commands would be run on your NBU master server)
### First you need to find the exact start time of the backup you want: nbumaster# bpimagelist -U -client CLIENTA -d 08/01/2001 -e /08/01/2001
Backed Up Expires Files KB C Sched Type Class ---------------- ---------- -------- --------
- ------------ ------------ 08/01/2001 05:05 08/15/2001 729846 52624096 N Full
Backup CLIENTA_OS 08/01/2001 02:05 11/02/2001 58233 5029312 N Full
Backup CLIENTA_DATA
### Next you use the -media flag to see what volume(s) were used for that backup: nbumaster# bpimagelist -media -U -client CLIENTA -d 08/01/2001 05:05 -e
08/01/2001 05:05
Media ID Last Written Server -------- ---------------- ---------- 602595 08/01/2001 05:05 nbumaster 603084 08/01/2001 05:05 nbumaster
Joe Holbrook, CHPTP XXXXX 66

• Verify Media status (available_media)
