An "mksysb" is always an image of the rootvg only. It is used to create a backup set with all the configuration/customization information of a system in place so that it can be set up again fast in case of a machine failure or to clone a system onto another one. In fact mksysb-format backups include boot blocks so it is possible to directly boot a system from such an image and restore it from it in one pass.

There is the more general command "savevg", which creates a backup for any volume group. "mksysb" is in fact using "savevg", but putting a boot block and other information in front of this image. gts1999 already told you about "savevg".

The destination for either a mksysb- or a savevg-image is classically a tape drive, but can be any device or file. Just make sure you have enough room for it on this device/file.

I hope this helps.
