How can I authorize a non-root user to do a system backup with 'mksysb'?
I use AIX 5.2 I want to allow a non-root user to do a system backup with 'mksysb' command.
I try to add 'ManageBackup' Role to that non-root user but it have an error "ksh: mksysb: 0403-006 Execute permission denied."
What should I do?

Have you considered using "sudo"? With this package installed you can specify certain commands to be run by a (group of) user(s) as root. You can even limit this to the prescribed usage of certain parameters (for instance, a user might be allowed to do a "ls -l" as root, but not a "ls -a", etc.).

It looks like you could tailor this to exactly your needs.

I hope this helps.

You might also SETUID the mksysb binary. Though, I would prefer (and already use) sudo...
Setting this bit is very dangerous and so, you should be VERY careful If you consider using it...

Regards.

Sorry, but "mksysb" is a shellscript. See the output of "file /usr/bin/mksysb".

Anyways, i suppose we agree upon "sudo" being by far the preferable solution.

Try the whereis command or sudo -V.

Oooops! No way. I just assumed it was a binnary file so forget it, I'm sorry.
Of course, sudo is as you said: by far, the preferable solution.
