The target system should have at least the same amount of disk space as the source system.The target database has sufficient disk space and memory. Prerequisites for Copying a Database Using Backup and Recovery: Note: if we are performing a recovery to different system - Target system and Source system must have the same configuration.IN Particular, the no.of DB services with their own persistence must be the same in both systems.Tenant databases can be recoverd via the relevant system database only. With #SAP HANA multi-tenant database containers, recovery using snapshots is not supported yet.There can be any number of hosts in the target system, provided that the number and type of services is identical in both the source and the target system.The #SAP HANA database software version used for the recovery must always be the same version or higher than the #SAP HANA database used to create the backup. A #SAP HANA database cannot be recovered to a #SAP HANA database with a lower software version.Specific Log Position: This recovery type is an advanced option that can be used in exceptional cases where a previous recovery failed.Specific data backup is required for the above type of recovery option.
Specific Data Backup: Used for recovering the database to a specified data backup. Point in Time: Used for recovering the database to the specific point in time. For this recovery the data backup and log backup have to be available since last data backup and log area are required to perform the above type recovery For this recovery the data backup and log backup have to be available since last data backup and log area are required to perform the above type recovery
Most Recent State: Used for recovering the database to the time as close as possible to the current time. Copy the backup file to your target system, restore it to a new database there, then run SWPM/HANA Studio to complete the copy.
For a SQL Server-based ABAP system, for instance, you can make an online backup of your source database without having to shut down the #SAP system, which means there is no downtime of the source system involved. Homogeneous system copy, choose the Backup/Restore method.
