Everyone, thanks for all the info.  Yes, I currently keep at "least" two sets of backups in various formats (DVD, CD, and/or external HD), been doing so for years, only they were all "uncompressed".  Needless to say, that makes for a lot discs laying around and a lot less space on the external.  And yes, I agree about NOT compressing files "collectively" but rather individually.... makes a lot of sense.   I may just end up using my double density DVDs (8.5 gigs) to store an uncompressed format version, and use the regular DVD's and external HD to store a compressed (zipped) format version. 

Thanks again for all your help/suggestions..... it's most appreciated.
