[rescue] Backups

[Charles Shannon Hendrix]

Stuff like this really should be in geeks.  In the past it seems like
you can never move discussions to the other list, but I'm crossposting
this one to geeks.

I actually would like for mine to live for awhile, because it is all I
have right now.

I do a lot of full backups onto CD, so I figure after doing this awhile,
I've got quite a lot of redundancy there.

What I'd really like to do is tie it together with an md5-keyed database
of files so I can find them easier.

Their CD media is the most compatible.  Supposedly the Phenyl* stuff is
more stable because it has metal in it.  I don't know if TY makes any
metal stabilized cyanine or not.

Each drive has a database of media descriptors with strategies for
burning them.  So does a lot of burning software.

The problem is that a company might buy a CD press (perhaps used) from
someone and fail to change the ID number.  If they don't do as good a
job, or run the machine long after it has worn out, it will fool the
drive.

Ah, it should have the newer burn chip in it.

I want very much to backup some games with *insane* copy protection.

Of course, usually what I do is buy a game and then use the pirate
utilities to disable the copy protection.  It's pretty bloody stupid to
have to get out a CD to use software that is on my hard drive.  That's
one big reason I have hard drives!

Me too... except that I haven't succeeded.

Yeah, well...

Another issue with CD/DVD backups is that a lot of the rescued hardware
we like to play with can't use them, but can still use some fairly
recent tape drives.

I think it would be funny, just for kicks, to do something like
interface a CD burner to an older IBM mainframe.

Then write JCL to burn a CD calling "IEHBURN" with gobs of parameters to
control the operation.
