Structure-Retaining Database Copy or Restore on Windows
If the database is on several drives on Windows, problems occur as follows:
Database copy with retained structure, that is,
backup_dev_type = disk_copy | disk_standby | stage_copy | stage_standby
)BRBACKUP attempts to copy all databases onto the drive which is defined in the
init<DBSID>.sap
parameternew_db_home
.Restore on another computer with changed database name:
BRRESTORE attempts to reload all databases to the drive which is defined in the environment variable
SAPDATA_HOME
.
In both cases the distribution of the database files to several drives is not maintained.
