[This question is based on the UNIX(r) System V Rel. 3.1.1 OS.] I'm looking for a good/quick explanation of this concept "shadowing" that folks seem to be throwing around lately. Will this only work if another duplicate processor is avail. - and idle normally? Is this really a practical way to have a "Cadillac" back-up/recovery procedure? What about incremental back-ups? I'm of the opinion that the project simply is not that crucial to have the system constantly backed-up (hourly?) in order to have almost a "hot switch" recovery process. Ideas? Suggestions? I'd appreciate any suggestions or comments you have. I believe I still have a copy (somewhere) of an incremental back-up program, but welcome copies of your programs. Thanx in advance, Tim Tromley att!mtuxo!trt
