    How do i burn a 7GB .iso file to a standard DVD?
    Disk Utility doesn't seem to allow it to be compressed or break the file up.

    It's probably a dual-layer DVD image - so you'd need to do this on one of the newer Macs.

    Toast will allow you to split the iso on to two DVD's as a back up but you have to put it back on a hard drive and rejoin it to mount and run it.

    Create 2 4GB disk images with disk utility. Mount the .iso in OSX (just double click it), copy the files to the 2 disk images. Burn the 2 disk images with disk utility. If the iso you're backing up is bootable then you'll loose this if you do this.

    This of course assumes you can split the files up into two chunks like this. If not you could do something with 'split' via the terminal to break up the iso into 2 chunks, burn each chunk to a dvd, then 'cat' them back together again when you need the original file.
