Thanks to the many users of this list that responded to my questions.
Here are the response that I received (Q=Question,A=Response):

Q: do you have to kill all processes b4 doing backup?
A: single-user mode better for full backup

Q: how do you check the max # of users a machine can support (not the #
of user processes)?
A: sysdef -i

Q: how do you check the security attribute of each user?
A: -/etc/passwd, .cshrc, .login {the uname setting}
   -type groups <user_name>

Q: how safe are TAR and CPIO for backup?
A: -use ufsdump (tar and cpio have limitations)
   -ufsdump is used for doing full backups (faster)
   -tar is used for dumping directory
   -tar good
Q: how do you access the kernel file to modify certain parameters --
where is it located?
A: -add stuff in /etc/systems file
   -in /etc/system, then REBOOT
   -system.h and then RECOMPILE

SURVEY: I am interested in knowing if anyone have read this summary,
please send me an email so that I can see who actually read this.

Thanks again for your help!
