- system copy it's better to be done with an offline backup, because no tx logs should be applied after - we can schedule an offline backup via crontab, or just run the backup_offline.ksh script - before starting the backup stop SAP, check if pmon is running, sap, etc.... - start the backup and meanwhile check the log file /oracle/S01/102_64/bin/namelogfile.log with fast –f ./namelogfile.log - after the backup is complete verify if all the data files were backed up correctly - delete te data files *.data* from /s01/sapdata1+2+3+4 ---find . -name "*.data*" -type f -exec rm {} \; - create the same directory structure in /S02/sapdata1+2+3+4 - after we should check the permisions on the new directory structure - next step is to unmount the /S01/sapdata1+2+3+4 - next we should mount /S02/sapdata1+2+3+4 - the backup log file is rdyzhxtr.rsb - next we have to modify the enviroment variable and chnage it from /usr/S01 to /usr/S02 - the backup file is bdyzhdsn.aff - before running the restore try brrestore -b bdyzhdsn.aff -m all -c -q check --to check for some eventual errors - restore using brrestore -b bdyzhdsn.aff -m all -c - after resore try to start SAP...hope for no errors... :D
