TheDiggler, why only 1.175GB? Thanks for the work around.
Anyone else?
I calculated that value based on the following facts as I know them to be:
a) A DVD-ROM can hold up to 4.7 gigs of data.
b) Norton Ghost, to the best of my knowledge, never produces an image file > 2 gigs in size (i.e. it forcibly SPANS in 2 GIG chunks unless you configure a different SMALLER span size).
4.7 gigs / 2 = 2.35 gigs (which is bigger than the maximum image file size of a Ghost Image Span)
4.7 gigs / 4 = 1.175 gigs (which is smaller than the maximum image file size of a Ghost Image Span)
I picked the 1.175 gig size for Ghost purposes so that you're producing the most efficient SPAN size w/o wasting any space on a DVD-ROM.
Lets say you went w/ the Ghost default of 2 gigs per Image Span. If you're backing up 30 gigs of data (assuming no compression for the sake of this example), that'll produce 15 2gig SPAN files. You'll be able to fit 2 SPAN files per DVD (i.e. 2 gigs x 2 files per DVD), for a total of 8 DVDs (wasting 700 megs of space per DVD).
If you produce 1.175 gig SPAN files, you'll end up with 25 1.175gig SPAN files and a small 26th SPAN file. All 26 of these files will fit on 7 DVDs. Thus, you're using 1 less DVD to backup your data w/ 1.175 gig chunks (because you're using your DVD space more efficiently).
If Drive Image lets you produce SPAN files > 2 gigs, I'd go with 4.7gig SPAN files (if possible), or 2.35gig SPAN files otherwise.
