Making A Back Up Disc of OS X 10.5 and 10.6 Upgrade

[yOGi420™]

I'm trying to make back ups of my originally purchased system discs so that I can use those to do any restores of my system any keep the originals in a safe place. I'm not quite sure what i need to do to successfully do this. Can someone please help me out. I Have 2 different macs that I can use to burn dvd's on but not sure if the drive can do this since I think that I might have to burn dbl layer discs. My iMac says it is a MATSHITA DVD-R UJ-85J and specs DVD-Write: -R, -R DL, -RW, +R, +R DL, +RW. Any info would be great.

You'll need a dual-layer disc for each backup you want to make. I'd make an image of the original disc using Disk Utility, then burn it to the DL DVD.

ok, so what program would be best to burn the dl disc with??

Disk Utility should allow you to burn the Leopard Install DVD.

Have you thought about cloning the install DVD's to an external USB hard drive or USB stick? Much easier than messing around with Dual Layer discs. See here : http://www.maciverse.com/installing-snow-leopard-onto-an-external-hard-drive.html

Toast will do it, as will Disk Utility or Burn.
