I have SAP system runing on AIX box. Need to take the offline backup and no tools available. Can you please suggest, which method can you use either by
TAR or SAVEVG or BACKUP
Destination Tape drive.
What do you mean "no tool available"?
If you don't have any vendor tool,the ones provided by the db and os is the best choice.You can backup db to disk if you have storage server like IBM DS8000 or FAStT and backup OS to tape .In addition, do remember to backup the import filesystem if they locate on the share storage,/usr/sap and /sapmnt.
Now your system is safe enough!
