Re: back up options

[Al Mac Wheel <macwheel99@xxxxxxxxxx>]

We ran into a variation of this when we had Machine/36 hosted by OS/400.
The reality was & probably still is, that objects on one operating system 
are entirely foreign to objects on another operating system, so what you 
could get was a backup of the ENTIRE system, like a SAVE-21.
You could not get partial backups, you could not get partial restores.

So example ... we discover that a person was deleting query definitions 
that they created and no longer using ... come to find out SOMEONE ELSE was 
using those queries & wanted them back.  In the current reality, we go to 
the last backup tape, before the deletions, and restore ONLY certain query 
definitions.

If one operating system stuff has been backed up using some other operating 
system, the other operating system thinks of the backed up stuff as a 
single object ... you cannot address the pieces in terms known to the OS 
that got backed up.

You need to plan your backup strategey to support access to pieces, perhaps 
both the backup in total, and key pieces in save files, if you have enough 
disk space, and a good naming system.
