IFS backup question

[ADMobius]

I want to back up the IFS (except QSYS and QDLS). I have seen 2 different commands that say they will back up everything except QSYS and QDLS, but what is the difference between these 2 commands?

SAV DEV('QSYS.LIB/TAP01.DEVD') OBJ(('/*') +
('/QSYS.LIB' *OMIT) ('/QDLS' *OMIT)) +
ENDOPT(*LEAVE)

AND

SAV DEV('QSYS.LIB/TAP01.DEVD') OBJ(('/') +
('/QSYS.LIB' *OMIT) ('/QDLS' *OMIT)) +
ENDOPT(*LEAVE)

Should it be OBJ('/') or OBJ('/*)

Re: IFS backup question

An Example to understand :
If you use OBJ(('/home/') SUBTREE(*ALL) the /home directory is saved (and the definition of the /home directory) with all sub directories and their contents.
OBJ(('/home/*') SUBTREE(*ALL) is identical as the previous command except for the definition of the /home directory which will not be backuped.

Then use OBJ(('/') to save the root definition
