Backup and RestoreLocate this document in the navigation structure

You must back up your system landscape regularly to ensure that you can restore and recover it in case of failure.

The backup and restore strategy for Search and Operational Analytics includes data backup and restore for the following components:

Component

Category

Data Type

Backup Method for Application Data

TREX or BWA or SAP HANA

IV.

Search index for business objects and files

Backup and recovery according to the relevant procedures for the technology used

ABAP

III.

Incoming temporary data of the BI extraction

Configuration data

Database and log backup (MaxDB)

Since Search and Operational Analytics is based on SAP NetWeaver AS for ABAP and a search and analysis technology (either Search and Classification (TREX), BWA, or SAP HANA), you have to use the standard backup/restore and recovery tools and procedures of these components.

Data Types in Search and Operational Analytics

The following data types can be distinguished in Search and Operational Analytics:

  • Application Data

    In the case of application data, these are the indexes created for searching. These indexes are stored in TREX. For the TREX servers, the standard TREX backup and recovery procedures apply.

  • Configuration Data

    The configuration data for the ABAP system is stored in the corresponding database tables. Search and Operational Analytics uses standard technology for configuration data and log information:

    • Search and Operational Analytics uses modified ABAP tables and SLG1 logs. These table entries must be considered during backup and restore.

    • Technical configuration data for TREX is stored in the directory /usr/sap/<SAPSID>/TRX<instance_no>/<trex_hostname> as configuration files in the format *.ini. The TREX configuration data that is displayed in transaction RZ20 for CCMS and GRMG is stored as XML files in the directory /usr/sap/<SAPSID>/TRX<instance_no>/trace/grmg with file names in the following format: GRMG_config. <SAPSID>_ <INSTANCE>. <host_name>.xml.

More Information

For more information about backup and restore, see the relevant sections of the technical operations manual for SAP NetWeaver.

Depending on the search and analysis technology used:

  • SAP HANA: Backup and Recovery section in the SAP HANA Technical Operations Manual

  • TREX: Data Backup and Restore for TREX

  • BWA: BW Accelerator High Availability section in the Technical Operations Manual SAP BW Accelerator 7.20 for SAP Business Warehouse

Note

The backup and the restore run of the ABAP databases and the TREX indexes must be carried out simultaneously. During the backup, no indexing or configuration changes are permitted.
