RE: Using DVD-RAM drive

You had a multipart question.  I thought I'd help you with the part that I 
worked with and/or cared about.  Let the software distributors talk about 
the other stuff.

RE: Using DVD-RAM drive










I was speculating more about the image format and what you had to do to
extract meaningful data off of it given that Vern had sugested downloading
it to a PC.  Granted, there are a few DVD-RAM drives available for PC's 
but
the vast majority of PC's use +-R drives.

You can do the RST* family of commands from a DVD provided it was saved
with the SAV* family of commands.

RE: Using DVD-RAM drive










How does a DVD-RAM image compare to a CD image or a DVD +-R/RW?  Does size
matter?  (insert your own joke here)  I'm not familiar with DVD-RAM but
DVD
+-R is 4.5GB compared to the 650MB or 700MB for a CD.  Also, archiving is
one thing but if you want to restore it can you just drop it in the DVD
drive on your iSeries and do a RST, RSTLIB, or RSTOBJ or do you have to
move the image back into an image catalog before you can restore it?

If you are on V5R3 you can create an image catalog entry that is writable.
This is in the IFS and acts like a writable optical device. The resulting
image file can be downloaded to a PC and burnt there. It is bound to be
much faster, although I've not tested this. You can even create multiple
entries, and the SAV will span the optical images, just as it does on
tape.
These can be created at 650meg CD size, all the way down to 48meg, IIRC,
and up to DVD sizes and larger.
