Backup/Restore and Recovery 

Usage type PI is based on both SAP NetWeaver usage types AS-ABAP and AS-Java. Therefore, you have to use the standard backup/restore and recovery tools and procedures of these usage types. For more information, see Backup and Recovery for AS-ABAP and Backing up and Restoring AS Java for AS-Java.

Backup and Recovery for Individual Tools and Engines:

Tool/Engine	Data	Backup and Recovery Method
System Landscape Directory	Original	Database and log backup.
Integration Builder	Original	Database and log backup; application log backup.
Integration Engine	Original (messages) and cache (configuration data from Integration Directory)	Database backup. Data consistency with sender and receiver systems must be taken into account.
Adapter Engine (J2EE)	Original (messages) and cache (configuration data from Integration Directory)	Database and log backup; application log backup. Data consistency with sender and receiver systems must be taken into account.
Runtime Workbench	Original	Database and log backup; application log backup.

The standard installation is all-in-one, which means that data of all tools and engines is stored in one database. An exception is the System Landscape Directory if it already exists on the customer side.

If the Adapter Engine is installed separately (as a non-central Adapter Engine) on a separate database instance, backup and recovery must be handled separately, too.
