All the objects? probably you are talking about saving the entire system?
CharlieBrown is right, use the SAV command to save all your libraries, and think to save the system’s licenced internal code and the QSYS library using the SAVSYS command.
Hope it complements the previous answer.
Assuming the your server is named MyServer1 and that you back it up into a savefile named QGPL/MYSAVF, the CL to back up all of the objects on it should be:
Lots of variations are possible.
You should probably review Backing up and recovering IXS or IXA-attached integrated Windows servers. Among its subtopics is Examples: Saving parts of integrated Windows servers.
Thanks for your input. It is indeed the IXS we want to backup on IBM i tapes from time to time, in additional to the Backup Exec our network manager is running.
The IFS is already being saved using the SAV command as suggested.
