And for system-wide backups i would use "mksysb" and "savevg" solely under AIX - neither "tar" nor any of the other aforementioned programs.
Just my 2 cents.

Pretty penny's.
Just remember that mksysb and savevg are just front-ends for backup.
In other words, backups on AIX are organized by volume groups. mksysb is specialized for rootvg and savevg is used for other volume groups.
Ignoring that rootvg also creates files needed to boot a system that basic content and layout is the same.
Note: when mksysb is written to a file, rather than bootable medium, there is no boot program appended to the file (see above).
restvg - restore volume group - is the standard tool for restoring backups created by savevg.
"Booting" is the normal interface for restoring an mksysb image. Since a file does not have a normal boot interface a nim server can be used to restore practically any mksysb image. Two commands are needed to create the resources needed to restore an mksysb image "asis".
And then a nim bos_inst command using the two resources just defined to boot and install the image.
Getting back to restvg:
restvg -l -f savevg_or_mksysb.file will tell you what is in the backup - sort of like doing an lsvg -l command.
That is all for now. Questions and Comments to see where this takes us.

Questions is other threads remind me the importance of clearing limits for root user.
This sets all ulimt settings to unlimited for root in /etc/security/limits
There may be reasons to hold some limits but this is a default I use in my nim fb_scripts (first boot scripts).
Note: you may need to perform a similar command for other applications using large files: e.g., oracle, itdsldap.
If you want to remove limits for everyone the command is simple (editing files is so 1985 :wink: )

I have several H80 machines, all with AIX 4.3.3. On these machines I have mksysb running for rootvg backups and savevg for non-rootvg backups.
