Saving system backup information

Edit online

When you are defining a mksysb NIM resource using the nim -o define -t mksysb command, the -a mksysb_flags=xxx attribute can be given the -p option, which prevents the mksysb image from being compressed.

Note: Due to the amount of space that this system backup is likely to occupy, the location into which the mksysb file is saved, specified by the -a location=xxx attribute, must be large-file enabled. Otherwise, errors can occur.
