What’s New in SAP HANA SPS10: Backup and RecoveryData backups: full and delta

Delta backups contain data that was changed

since the last full data backup

Two types of delta backups are available:

Incremental and differential

Note: Delta backups are data backups – they

contain actual data. In contrast, log backups

contain redo log entries (sequence of changes)

F

Full data backup

– all data

I I I

Incremental backup

– changed data since

the last data backup

(full or delta)

DDifferential backup

– changed data since

the last full backup

A full data backups contains all current data

Note: Old data that is no longer valid but might still

be physically present in the data volumes is not

part of the data backup


What’s New in SAP HANA SPS10: Backup and RecoveryDelta backups – when to use what

Incremental backups...

...are usually small

faster backup

...are restored one after the other during a recovery

longer recovery times

Differential backups...

...increase the amount of data saved with each backup

longer backup times

...reduce the number of data backups during recovery

faster recovery

You can also mix incremental and differential

backups in your backup strategy

F

Full data backup

I I I

Incremental backup

DDifferential backup


What’s New in SAP HANA SPS10: Backup and RecoveryDelta backups – Creating a delta backup

Delta backups can be created using SAP HANA

Studio

Prerequisites: System privilege BACKUP OPERATOR

or BACKUP ADMIN; DATABASE ADMIN (for MDC)

1. In the Systems view in SAP HANA Studio, right-click

on the system and choose Backup and Recovery

Backup System...

2. Choose the backup type, for a delta backup: either

Differential Data Backup or Incremental Data Backup,

and specify further settings

3. Start the backup


What’s New in SAP HANA SPS10: Backup and RecoveryDelta backups – Backup catalog

Delta backups are included in the backup

catalog

In SAP HANA Studio, they are hidden by default

Prerequisites: System privilege BACKUP OPERATOR

or BACKUP ADMIN; DATABASE ADMIN (for MDC)

1. In the Systems view in SAP HANA Studio, double-

click on Backup and open the Backup Catalog tab

2. Select Show Delta Backups


What’s New in SAP HANA SPS10: Backup and RecoveryDelta backups – Backup lifecycle management

Backup lifecycle management now also

includes delta backups

Deleting old data backups

Prerequisites: System privilege BACKUP ADMIN;

DATABASE ADMIN (for MDC)

When choosing to delete all backups older than a

specified full backup, older delta backups will also be

deleted along with older full backups and log backups


What’s New in SAP HANA SPS10: Backup and RecoveryDelta backups – Backint support

Delta backups are compatible with the current Backint API specification

There are a few points that you need to be aware of when using a 3rd party backup tool

For delta data backups, SAP HANA is using the Backint option -l LOG in combination with the data Backint

parameter file given as option-p /usr/sap/<SID>/SYS/global/hdb/opt/hdbconfig/init<SID>Data.utl

The Backint parameter file is tool-specific and typically contains information like the backup destination (the

name of the backup container/pool in the 3rd party backup tool that is used to store the backup).

Note that some 3rd party backup tools support only one Backint parameter file for both data and log backups

In some cases backup tools use the Backint option -l to determine the suitable backup container from the

Backint parameter file, which means that for the option –l LOG the log backup container is used.

Caution: Backup containers that were until SPS10 only used for log backups may be sized too small for delta

backups. This could lead to a database standstill due to a log full situation.

Recommendation: Ask your 3rd party backup tool vendor for details on how to configure the

respective 3rd party backup tool for usage with delta backups. If in doubt configure two dedicated

Backint parameter files: one for data backups, and one for log backups.


What’s New in SAP HANA SPS10: Backup and RecoveryDelta backups – SQL commands

What’s New in SAP HANA SPS10: Backup and RecoveryRecovery using delta backups – Tool support

Recovery includes delta backups automatically

Recovering to the latest point in time using SAP HANA Studio

Prerequisites: Credentials of <sid>adm operating system user

1. In the Systems view in SAP HANA studio, right-click on the system,

choose Backup and Recovery Recover System... and enter the

required credentials. The system is shut down.

2. Select the recovery type and specify the log backup location

3. Select the full backup upon which the recovery is to be based

4. Specify further recovery settings as usual.

If you do not want SAP HANA to use delta backups for the recovery,

de-select Use Delta Backups. Note: If you do not exclude delta backups,

SAP HANA automatically determines the best recovery strategy based

on all available backups, including delta backups.

5. Start the recovery


What’s New in SAP HANA SPS10: Backup and RecoveryRecovery using delta backups – SQL commands

If delta backups are available, SAP HANA per default uses them for recovery

If you do not want delta backups to be used in a recovery, you need to specify this explicitly.

Executing the database to a point in time, excluding delta backups

Prerequisites: Credentials of <sid>adm operating system user, or system privilege DATABASE ADMIN (for

tenant databases in MDC system)

RECOVER DATABASE UNTIL TIMESTAMP '2015-05-15 10:00:00' IGNORE DELTA DATA BACKUPS


What’s New in SAP HANA SPS10: Backup and RecoveryRecovery using delta backups – Identify required backups using hdbbackupdiag

You can use hdbbackupdiag to display the backups required for a recovery of the database

This helps you to keep the quantity of the files that have to be made available to a minimum.

Finding out which backups are required for a recovery to a specified point in time

Prerequisites: You are logged on to the database server with the operating system user <sid>adm and have

read authorization for the backup location. For more information, see the SAP HANA Administration Guide.

http://help.sap.com/hana/SAP_HANA_Administration_Guide_en.pdf

Support for multitenant

database containers


What’s New in SAP HANA SPS10: Backup and RecoveryMultitenant database containers: Backup/recovery concept

MDC systems follow the same backup/recovery principles as single-container systems

The system database plays a central role for MDC backup and recovery

It can initiate both backups of the system database itself and of individual tenants databases. A tenant database

can also carry out its own backups unless this feature has been disabled for this tenant database

Recoveries are always initiated from the system database

To recover a complete MDC system, the system database and all tenants need to be recovered

individually

Note: Snapshots are currently not supported


What’s New in SAP HANA SPS10: Backup and RecoveryMultitenant database containers: SAP HANA Cockpit support

You can use SAP HANA Cockpit to create data

backups of the system database and of

individual tenant databases

Log on to the relevant database and click on the

Data Backup tile

Create data backups and view backup information

in the same way as for single-container databases

Note: You can also use SAP HANA Studio to create

data backups. Backup lifecycle management is

currently not available in SAP HANA Cockpit.


SAP HANA Backup and RecoveryMultitenant database containers: Backint support

The current Backint API specification also covers MDC systems

There are a few points that you need to be aware of when using a 3rd party backup tool

Isolation level “high”

With SPS10, a new option “isolation level” was introduced for MDC systems. If the isolation level is set

to high, all tenant databases run under individual operating system users.

In high isolation scenarios, Backint is supported from the SAP HANA side but you need to check with

your 3rd party tool vendor whether any tool-specific restrictions apply.

Tenant copy

Tenant copy using Backint is currently not supported. Use file system backups for tenant copy instead.
