I can tell you that both will work. That's the good part! BUT if you are doing your backup to a REMOTE image catalog, that is, one hosted on NFS then you cannot use the VFYIMGCLG command to rebuild the BOOTP directory. Reason is that all you have is access to the virtually mounted ISOs not to the file system next to them.

So you would need to backup to a LOCAL Image catalog, rebuilt BOOTP there, and then transfer that directory along with the ISOs off to the target Linux server. All doable of course, but more steps and more opportunity for errors.

For example if you find you need to regen the BOOTP directory contents but all you have is the images on Linux, then you may be stuck.

That's why I feel backups should be automated. Including secondary measures like ensuring boot stuff is current.

Some ideas about this topic:

- regarding SAVSYS automation, in place of SAVE menu option 21, you can use the capability to run a job in batch restricted state: in your CL program which does the SAVSYS, include ENDSBS SBS(*ALL) BCHTIMLMT(somevalue). This job can be scheduled just like any other, but must run in the controlling subsystem; checkout https://www.ibm.com/ docs/en/i/7.3?topic=ssw_ibm_i_73/cl/endsbs.html and https://www.ibm.com/ support/pages/running-full-system-save-or-savsys-restricted-state-batch

- regarding BOOTP stuff, at the end of your program, you could try to run the VFYIMGCLG TYPE(*UPGRADE) NFSSHR(*YES) command; conditions exist regarding the content of image catalog in order for the restore to succeed, checkout https://www.ibm.com/docs/en/i/7.3?topic=ssw_ibm_i_73/ cl/vfyimgclg.html

The first item works as it is used by BRMS. For the second one, this is just an idea and never tried it (and I don't have a position where I can test it!).
