I woulld like to know, how to execute the regular SAP OS backup and have the following questions regarding this issue:
1) How often should I backup the SAP-Binaries-partition \usr\sap\...?
(daily, weekly, 1 times month)
2) Should the DB, SAP R/3 or some Services be stopped for this issue?
Do exist some file-locks avoiding offline backup of \usr\sap\... ?
3) What should be backuped from \usr\sap\...?
Thank you very much!
