HI everyone,
I had know the method of "help.sap.com".
1. Backup Database.
2. File system backup.
But when I copy the file of the SAP system directory /usr/sap/<SID>,
there are some files can't be copy because of file name is too long or the directory is too deep.
Then I compressed compress the file of the SAP system directory /usr/sap/<SID>, but there are several files can't be compress.
Is there anybody had met this problem and give me any advice?
What is the most applied mothod of Portal backup and recovery?
Best Regards,
Jianguo Chen
