More often than not, making a backup of a backup is not a wise idea. Everytime a backup is made, there are certain anomolies (errors or deviations from the orginals) that can appear even if they are small ones and not easily noticed. These can be made worse in the copy of the copy. In most software burning manuals it tells you this. Think of it this way. Let's say that you made a copy of a VHS or audio tape, then made a copy of the copy, you would notice that the quality is degraded. CD's are pratically the same way.

Doom, you're way off-base here. The "FADE" you speak of is in ANALOG recordings such as tapes. Digital medium does not suffer the same sort of problems. A good copier that takes into account sector placement and timing can copy ANYTHING short of copy-protected discs. Audio tapes, VHS tapes, even Reel-to-Reel tapes suffer from multi-generational fading, or "Anomolies due to copying" as you called it. Digital data doesn't suffer from that sort of problem. The data is either a ONE (Data-bit ON) or a ZERO (Data-bit OFF) and there is no in-between. Digital tapes (DAT, compact digital tape, etc) don't suffer from fade. MD (MiniDisc) can suffer from fade when copying because most commonly, the person copying the songs will use an analog (AUDIO) means of copying. If you copy an MD via a digital cable, even it is immune to fade.
Software manuals
do not talk of the fade or errors you mention because software is DIGITAL, not ANALOG.
One last note: get your facts straight...
