A typical mksysb image is generally in a size range from about 91MB to about
1.5GB

it also depends on what version of AIX u r using ... but typically it comes to around within 1.5GB

I think it depends on the sizes of all mounted file systems..

Please correct me if i am wrong.

Thanks

man mksysb

Quote:
The mksysb command creates a backup of the operating system (that is, the root
volume group). You can use this backup to reinstall a system to its original
state after it has been corrupted. If you create the backup on tape, the tape is
bootable and includes the installation programs needed to install from the
backup.

The file-system image is in backup-file format. The tape format includes a boot
image, a bosinstall image, and an empty table of contents followed by the system
backup (root volume group) image. The root volume group image is in backup-file
format, starting with the data files and then any optional map files.
