A save file (*SAVF) is simply a single membered unkeyed physical file that
is 528 bytes in length.  The OVRSAVF command allows you to read the file in
a program, although you can't muck with the contents, because IBM writes a
checksum byte at the end, and if you've mucked with it, it won't restore.
On the other hand, if you want to lock it up so no one can restore from it,
you can change it, but only if you know how to change it back exactly.

The nifty thing about the iSeries is that if you use SAVLIB to save
an entire library, you can use RSTOBJ and pluck a single object out
of the save and restore it!

So, if the save file (or backup tape) has a library in it (on it) you
can restore the entire library, or just selected objects.

My perception of a save file is that IBM wrote a 'device driver'
called a save file.  When you do saves/restores to a save file, your
job will sometimes show SAVFWAIT as the status-- similar to TAPEWAIT
for a physical device.  I think the operating system sees a save file
is another tape device!

You can also save the save file data (SAVSAVFDTA (??)) from the file
to a physical tape device.  This transfers the contents of the save
file to the tape file.  Once you've done this, you can restore from
tape as if the save had been to the tape device in the first place!
