Gestión de Media.Media Manager

Conceptos de Media Manager

Volumes : Piezas individuales de mediaVolume Pools : Media usada para un proposito comúnVolume Groups : Media en una localización física Común.

Volumenes

Volumenes son :• Media magnética ( tapes ) ó Discos ópticos• Son gestionados por Media Manager.

Son identificados de forma única mediante• External VSN ( Código de Barras )• Internal VSN ( Label ).Escritura en banda

magnética.

EVSN Codigo de Barras

Volumes Pools

Conjunto de volúmenes, en los que almacenaremos datos con una característica común.• Han de ser creados antes de que podamos

asignarles volumenes.

Pool OpcionalCuando un volume pool no tiene volúmenes para escribir datos, un volumen es asignado desde el pool de SCRATCHPara crear un scratch pool:• Editar vm.conf

SCRATCH_POOL = nombre• Reiniciar procesos de Media Manager

Volume Groups

Identifican la localización fisica de un volumen.Son creados para realizar un seguimiento más exhaustivo de donde se encuentra un volumen.

Alta de media en NetBackup

!!!! Media Type Volumen = Media Type Drive !!!

Ejemplo Practico. Alta de media en un drive StandAlone

Configuración de Media en Robots

Agregando media a un Robot

Método Manual :• Igual que en StandAlone más información de

residencia.CAP.

Inventario : • Interrogar a la librería por su contenido.• Solo librerías con lector de código de barras!!!.

Inventario de un Robot con Lector Código de Barras

“Show Contents”“Compare Robot Contents with Volume Configuration”“Preview Volume Configuration Update”“Perform Volume Configuration Update”.• Empty Media Access Port Prior to Update.

Slot 1 ORA-001Slot 2

.

.

. Volume Database

Opciones de Inventario

Reglas de Código de Barras :• De acuerdo al código de barras detectado,

agregar el volumen a un volume pool especifico.

Asignar la media agregada/eliminada del Robot a un Volume group especifico.Asignar un rango especifico de VSN a volumenes agregados.Media de un tipo específico asignar a un volume pool especifico.

Eliminación de volumenes en un drive StandAlone.

No deben de contener backups válidos.• Time Assigned !!!!

Seleccionar volúmenes y eliminar.

Eliminación/expulsión de media en un Robot

Expulsar un volumen : Seleccionar un volumen “eject from robot”Eliminación:• Time Assigned.

El problema del inventario en un robot sin código de barras

NetBackup al preguntar por el contenido de la librería solo detecta la presencia de cartuchos o no, en cada slot.Asigna un rango de EVSN por defecto o previamente configurado y los agrega a su base de datos de volumenes.Cuando escriba en un volumen por primera vez etiquetará (LABEL) dicho volumen de acuerdo al rango previamente asignado.

En NetBackup

LABEL = codigo de Barras

STORAGE UNITS

Storage: Dispositivos vs Unidades

Dispositivos de Almacenamiento: • Sitio individual donde escribir backups.

– Tape Drives, discos opticos etc..

Storage Units (STU) : Uno o más dispositivos de almacenamiento sobre un media server, a el cual los backups son enviados.• Pueden incluir varios dispositivos de

almacenamiento.• Han de ser del mismo tipo y densidad.• Los dispositivos estan bajo el control del mismo

robot.

Storage Units II

Políticas de Backup

Políticas. Definición

Una política es una petición de backup de un conjunto de clientes con un “File List”común.Una política determina :• Qué ?• Quién ?• Cómo ?• Donde ?• Cuándo ?

Elementos de un Política

Clientes• UNIX, NT, Macintosh, NetWare, etc

File List• Ficheros, directorios, file systems, etc….

Atributos• Cross mount points, compression, multiplexing, etc.

Schedules• Cuando iniciar el backup, nivel de retención, etc…

Clientes

Conjunto de máquinas de las que realizaremos el backup.• Misma plataforma ( UNIX, NT )

Es necesaria la instalación de un agente.• Instalación de binarios en el cliente y confguración básica• UNIX :

– Posibilidad de instalación remota desde el Master ( GUI, CLI ). Es necesaria relación de confianza.

• Windows :– Instalación local

Se requiere que la resolución de nombres entre el master/medias y el cliente este correctamente configurada. MANDATORY !!!!

Installing Patches

After installing NetBackup, it is important to install any necessary patches as recommended on the VERITAS Support Web site.

NetBackup patches, or NB patches, arepatches for the NetBackup server software andclient software.

Review the readme file before installing.Drive mapping patches contain updated drivemappings for robotic drive mappings used byMedia Manager.The patch naming scheme is broken down asfollows:

NB_34_1_3.win95_246538.exe

Type of patch Version Platform Patch ID


Uninstalling Patches

The patch uninstaller is a new feature of NetBackup 4.5:

On UNIX systems, only the last installed patch of a certain product/subproduct may be uninstalled.

Uninstall patches in reverse-sequential order.

On Microsoft Windows systems, only the last installed patch can be uninstalled.This feature should not be used to uninstall any patches previous to the NetBackup 4.5 release.Refer to the README file supplied with each patch for specific instructions.


Troubleshooting

Common Installation IssuesNetwork/communication issues: • Ping by name between master server, media

servers, and all clients.• Start or communicate with NetBackup services.• Ensure ports/service entries on each media

server and client match entries on master server.

Host communications setupMisspelled or incorrect host names

NetBackup requires reverse name lookup.

Incomplete or incorrect device installationor configuration

Two-part catalog:• ltidevs—Tape and optical devices• robotic_def—Robotic devices

One device catalog per media server, which contains:• Device type• Operating system access information• Hardware status

ltid starts vmd and reads the catalog upon startup to determine the devices it controls.• If devices have been configured, then avrd and the

appropriate device controllers are started.• If no devices have been configured, ltid shuts

down without starting avrd or the device controllers.The catalog is empty upon installation.

To configure the first device using the Media andDevice Management interface, vmd must be running.


Configuring Devices

PrerequisitesHardware devices must be attached to the server that acts as the device host.Appropriate drivers must be installed.Use operating system utilities (such as Device Manager) to verify that devices are accessible.

Shared (Multihosted) Drives

Drive sharing (also known as multihosting) isa feature of the Shared Storage Option (SSO).

SSO is a separately priced option.

SSO supports dynamic allocation and deallocation of drives across multiple NetBackup media servers.Shared Storage Option Resiliency is a new feature of NetBackup 4.5.• SSO Resiliency isolates media server drive

issues, preventing multiple failures.• SSO Resiliency dynamically remaps tape

drives upon the start of the devicemanagement service.

Robotic Test Tools

Test a robot without NetBackup.Move media within the robot fornon-NetBackup functions.Front-end application is robtest, which is located at install_path\Volmgr\bin\robtest.exe• This application invokes the device-specific test

tool (such as tl8test and tldtest).• The robot must be configured in order to use the

robtest menu interface.• A device-specific test tool can be invoked if the

robot is not configured.robtest is especially useful for validating drive mappings within a robot.


robtest Interface


Using Robotic Test Tools


Cleaning Drives

Using a Cleaning TapeIt is recommended that you specify the number of cleanings that remain for each cleaning tape. It is important to clean your tape drives, but be careful not to underclean or overclean.There are different drive cleaning methods that you can use:• Hardware-based cleaning based on drive alerts• Frequency cleaning configured within the

NetBackup software• Manual drive cleaning


Hardware-Based Cleaning

The robot must support hardware-based cleaning.The TapeAlert feature of NetBackup allows reactive cleaning for most drive types.The tape drive sends a notification to the robot that it requires cleaning.After backup tape is unmounted, NetBackup mounts the cleaning tape and cleans the drive.Hardware-based cleaning is the supported cleaning method in a SAN environment.


Frequency-Based Cleaning

Use the tpclean command to specify the number of hours a drive is used between drive cleanings (cleaning frequency).

Refer to the recommended frequency from the drive manufacturer.

Media Manager updates the mount time for the drive each time a tape is unmounted.A cleaning tape is configured in the robot; cleaning occurs when the accumulated mount time exceeds the time that you specified for cleaning frequency.Frequency-based cleaning is not supported for shared drives.


Manual Drive Cleaning

Use tpclean to manually clean the drive and reset the accumulated mount time to zero after cleaning the drive.You can manually clean a drive regardless of the cleaning frequency and accumulated mount time.Clean stand-alone and robotic drives if a cleaning tape of the correct media type and volume pool has been configured.


Troubleshooting

Common device configuration issues:Devices not recognized by operating systemIncorrect device definitionServices or processes not running“Downed” drives:• Hardware problems• Bad media• Misconfigured robotic drive


Summary

You should now be able to: Describe the Media Manager architecture, services, and network structure.Describe the device catalog configuration and contents.Identify the prerequisites of configuring devices.Configure tape libraries and tape drives.

Volume Catalog

The volume catalog is one of the internal catalogs where Media Manager stores information about:

Volumes: Individual pieces of mediaVolume pools: Media used for a commonpurposeScratch volume pool: A volume pool that enables Media Manager to logically move tapesinto volume pools that do not have mediaavailable to useVolume groups: A group used by theadministrator and Media Manager for trackingthe physical location of volumes


Volumes

Volumes are media (tapes or optical disks) that have been assigned a media ID.Volumes are owned and managed by Media Manager until they are assigned.Each volume has a unique volume serial number (also called a media ID):• External volume serial number (EVSN)• Recorded volume serial number (RVSN)

Media ID is limited to six characters.Use the Robot Inventory Media ID Generation rule to specify which six characters to use for the Media ID.


Volume Pools

Volume pools identify a logical set of volumes. Volume pools can be used to reserve media for specific NetBackup jobs.A volume pool must exist before volumes may be assigned to it.The following volume pools are automatically created:• NetBackup: For backups of NetBackup catalogs• None: For jobs other than NetBackup• DataStore: Reserved for use by VERITAS or its

partners who provide agents that integrate with NetBackup.


Volume Pools Example

Objectives

After completing this lesson, you will be able to:Describe storage units.Create and maintain disk (file system) and Media Manager storage units.Break up a single image into multiple fragments by using fragmentation.Describe the concept of multiplexing.Create and maintain storage unit groups.Troubleshoot common storage unit issues.


Storage Units

A storage unit is a group of one or more storage devices of a specific type and density that attach to a media server.Four types of storage units:• Media Manager: Robotic or stand-alone that is

under Media Manager control• Disk: A directory on a disk that stores the

backup or archive data• NDMP (Network Data Management Protocol):

Drives controlled by Media Manager but that attach to NDMP hosts and require that you have the NetBackup for NDMP option installed

• Fastrax: Controlled by Media Manager but attach to Fastrax hosts and require that you have theNetBackup for EMC Fastrax option installed


What Is the Difference?

A Storage Device is an individual place to write backups:• Tape drives• Optical disk drives• Magnetic disk with file system

A Storage Unit (STU) is one or more storage deviceson one media server to which backups are sent:• Includes one or more storage devices• Same type and density devices (robotic or

stand-alone)• Controlled by the same robot

A Storage Unit Group is a group used to identify storage units as a group• Available for various types of storage units• Determine the priority of storage units

File List Rules for UNIX Clients

Dependent upon client platform“/” with “Cross Mount Points” selected backs up all local file systemsFile list rules:• Enter one pathname per line. NetBackup supports a

maximum path length of 1023 characters on UNIX clients.• Start all pathnames with a slash (/).• You can use the following meta or wildcard characters in

policy file lists: *, ?, and [ ].• The following are sample UNIX file specifications that use

this capability:– /logs/daily_log[1234567]

Back up daily_log1, daily_log2, daily_log3…under the /logs directory.

– /etc/*.confBack up any file that ends with .conf in the /etcdirectory.

Lesson 7Monitoring NetBackup Activity


Course Overview

Configuring Media










Restoring Data



Objectives

After completing this lesson, you will be able to: Describe the NetBackup bpsched process.

Monitor NetBackup activity using the Activity Monitor.Access NetBackup reports.Enable NetBackup and Media Manager logging.


The bpsched Process

1. Every wakeup interval bprd starts a bpsched process:bpsched process scans the NetBackup policy configuration looking for work to do.

2. For each policy, bpsched checks for a schedule with an open backup window.

3. For each client:a. Calendar-based backups are queued automatically.b. For frequency-based backups, the period since the

last appropriate backup is compared with the schedule frequency. If the period is greater than the frequency, a backup job is queued.

4. If the job fails, retry the job as set in the Host Properties (Global Attributes) of the master server.

If the job still fails, it is reported as a failure.


Global NetBackup Attributes


Performing AutomaticScheduled Backups

In processing a policy with a schedule and an open window, a job is created for each client in the policy client list for which a backup is due to be performed.• If multiple data streams are enabled for the

policy, then NetBackup creates multiple jobs for a single client.

• Create a separate job for each data stream defined by the policy file list.

Clients are processed in the order in which they are displayed in the policy client list.


Performing Manual Backups

As the NetBackup administrator, you have the capability of initiating a manual backup.

Manual backups are sometimes called immediate backups.

The following are common reasons for running manual backups: Exception conditions; you want to:• Test a configuration.• Make up for a missed or failed backup.• Preserve an old configuration prior to

upgrading.


Initiating a Manual Backup


Activity Monitor Interface

The NetBackup Activity Monitor lets you:Monitor the progress of backups, archives, restores, duplicates, vaults, imports, and catalog backups.Monitor, stop, and start NetBackup andMedia Manager daemons and processes.Cancel uncompleted jobs.Save and print job information.Troubleshoot failed jobs.Monitor the status of drives.Change the operating mode of drives.

User-Directed Operations

End users can (if enabled) perform user-directed backups or archives:• There must be a user backup schedule in the

policy which defines the window during which a user can initiate a user backup.

• The client must be on the client list in the policy.• Users select files and directories to back up.• NetBackup ignores the file list in the policy.

An archive operation deletes the files on the client following a successful backup of those files.End users can obtain status information using progress logs and e-mail notifications.

Restoring Data



Objectives

After completing this lesson, you will be able to:Describe the restore process.Restore from multiple images.Use the NetBackup Backup, Archive, and Restore interface to restore data.Restore to an alternative client.Troubleshoot common restore issues.


Restore Operations

Restores are not scheduled.File transfers occur in the background.The administrator can restore data from any client in the NetBackup domain to any other client in the NetBackup domain (“push”).

This is known as a server-directed restore.Restores can be performed on the client side (“pull”), by client request.• If a client performs a user-directed backup,

the client has, by default, the ability to initiatea restore.

• This is known as a user-directed restore.True-image restores recreate contents of a directory to what it was at the time of any scheduled full through incremental series of backups.


Restoring from Multiple Images

Restores from full and incremental backups:• The default search range is the most recent

backups since the last full backup.• Specify a search range to restore an older

version of a folder or file.

Restore from a backup series:• Cumulative incremental backups require a full

backup and the last cumulative in the series.• Differential incremental backups require a full

backup and all differentials in the series.

Restore a specific version of a file or directory: • Specify the desired date range for the search.• Select only backups that include the version of

the directory or file you want to restore.


Invoking the Backup, Archive,and Restore Interface

catalog when NetBackup mounts a tape and attempts to write an image to that tape.

• Volumes are deassigned and deleted from the media catalog when all images on the volume expire.

• Look for entry in the Time Assigned field.• The media catalog also tracks media states

(FROZEN, AVAILABLE…)

Media Selection Flow

NetBackup searches the media catalog for a volume that:• Is located in the specified storage unit within a

storage unit group (if applicable)• Matches the requested volume pool • Matches retention level of the schedule• Is not FULL, FROZEN, IMPORTED, SUSPENDED,

or DBBACKUP• Is not currently in use

A mounted volume that meets these requirements is preferred.An unmounted volume will be selected if a mounted volume is unavailable.

Volume with the least number of mounts is picked if more than one is available.


Volume Expirationvs. Image Expiration

Volume expiration• Media Manager function• Relates to “freshness” of a volume• Not set by default

Image expiration• NetBackup function• Relates to need for the data on the volume• Set in the schedule within a backup policy

Image retention periods in general are less than volume expiration (except for an infinite retention period), and therefore a volume is automatically recycled many times during its lifetime.


Volume Expiration Date


Importing Backup Images

Importing images restores image entries by reading backup headers from tape:• Reinstate expired images.• Import images from another NetBackup domain.

Media IDs are added to the volume catalog(Media Manager catalog) on the master server.Media IDs are added to the NetBackup media catalog on the media server and images are added to the NetBackup image catalog.NetBackup Administration interface Images menu or command line.Two part process:• Part one—Initiating the import• Part two—Importing the image

After completing this lesson, you will be able to:Describe the NetBackup catalogs.Outline considerations to be made for the backup of the NetBackup catalogs.Back up the NetBackup catalogs.Restore the NetBackup catalogs.Control the size of the NetBackup catalogs.Troubleshoot common issues with the NetBackup catalogs.


NetBackup Catalogs

Catalogs are internal databases containing information about the NetBackup configuration and any backups that have been performed.

Master Server Catalogs:• NetBackup Catalogs

– Images – Jobs– Class – Error– Config – Vault

• Media Manager Catalogs– Volume – Global Device

Media Server Catalogs:• NetBackup Catalogs

Media• Media Manager Catalogs

Device


Where Are the Catalog Files?

Master Server Catalogs• install_path\NetBackup\db

• install_path\Volmgr\database

• install_path\NetBackup\var

Media Server Catalogs• install_path\NetBackup\db

• install_path\Volmgr\database

• install_path\NetBackup\var


Important Points to Remember

NetBackup catalog considerations:• Maintain a hard copy of the media IDs and their

physical location.• A current copy of the NetBackup catalog backup

tape must accompany tapes moving offsite.• There is an alternative backup method to secure

very large catalogs.Refer to the NetBackup System Administrator’s Guide.

NetBackup catalog backups:• Should be backed up regularly• Should be run only when there is no other activity• Take precedence over all other backups, if automatic• Should not be manually compressed• Should include media servers• Overwrite existing data when written to tape• Can be monitored in the Activity Monitor

Controlling Image Catalog Size Using Compression


File System Considerations

It is strongly recommended that you install NetBackup on a partition that can be dynamically enlarged using a product such as VERITAS Volume Manager.If NetBackup is installed on a static partition, the images catalog might outgrow your partition.

You can move the images catalog to another file system as follows:1. Check that no backups are occurring.2. Terminate the NetBackup services.3. Create the images directory in the new partition.4. Move the client images to the new location.5. Create an ALTPATH from

install_path\NetBackup\db\images\client_name to the new location.

6. Add the alternative location to the NetBackup catalog backup configuration.


Troubleshooting Common NetBackup Catalog Issues

Misconfigured:• Media• File list• Frequency

Media unavailable:• Not mounted in nonrobotic device• Not in robotic device

Catalog sizing:• Disk space• Media

Appendix CConverting Backup Exec Catalogs

C-2© Copyright 2002 VERITAS NBU_4.5_NT_R1.0_20020617

Converting Backup Exec Catalogs

Steps for using NetBackup to restore files backed up by Backup Exec:1. Install NetBackup with the Backup Exec Tape Reader

option.2. Configure devices and volumes in NetBackup.3. Convert Backup Exec catalogs.4. Browse for a Backup Exec file to restore.5. Restore files backed up by Backup Exec.

Methods for converting Backup Exec Catalogs using beconv:• Convert all Backup Exec media.• Convert Backup Exec media in a specific robot.• Convert Backup Exec media by slot on a robot without bar

code support.• Convert a single piece or a group of Backup Exec media.• Check database consistency for duplicate media IDs or

globally unique identifiers (GUIDs).


Conversion Utility (beconv)

Conversion utility Descriptionbeconv -all Convert all the media present on the

Backup Exec server or the Backup Exec configuration has only stand-alone drives.

beconv –rn Convert media that belongs exclusively to a particular robot.

beconv –tbs Convert media by slot on a robot without bar code support.

beconv –m Convert a single piece of media or a group of media belonging to the same family to NetBackup media.

beconv –check_consistency

Check the consistency of the volume databases with respect to media records having duplicated media IDs or GUIDs.


After the Backup Exec Catalogsare Converted

Once the Backup Exec catalogs have been converted:

Backup Exec file list requests can be generated.Backup Exec restore requests can be generated.Backup Exec images can be imported by using NetBackup (if the Backup Exec Tape Reader option was installed).

Selecting a Media Rotation Method

Media rotation is part of the backup strategy to:• Minimize tape wear• Maximize copies of data

Three Examples of Media Rotation Methods • Son: Easiest to manage • Father/Son: Mixture of full and partial backups• Grandfather: Most common strategy


Son Media Rotation Method


Father/Son Media Rotation Method


Grandfather Media Rotation Method


Determining Backup Horizons

The backup horizon: • Determined by how long data needs to be kept• Varies depending on company, department, and

government requirements

Different types of data have different horizons:• No horizon• Hours• Days • Weeks• Months• Years• Forever


Types of Backups

Full

Cumulative

Differential


Determining Backup Methods

Full: All data on a volume.Differential: All selected files since the last full backupIncremental: Files that have changed since the last full or incremental backupDaily: Files that were changed or created todayCopy: All selected data, does not affect any media rotation schemeWorking set: Data that has been created and modified since the last full or incremental backup all files accessed within the last x days can be includedArchive: Files deleted from the volume after being successfully backed up

Incremental Versus Differential

Incremental backups take less time and fewer tapes than differential backups.File versioning is somewhat easier with incremental backups.Differential backups allow for faster full-system recovery.Incremental and differential backup types should not be run on the same files. Select one method or the other.


Defining Backup Windows

The backup window answers the question: • When is data available for backup?• Can occur at various times • Can be various lengths

The length of a backup window depends on: • Applications• Business function• Data availability • Tape drive availability

Considerations for defining the backup window: • Running backups degrades system

performance.• Some services may need to be shutdown.
