"On-line" backup (RAID, snapshots, etc...) is not a replacement for "off-line" backup (tape, RRD, maybe some HDs), although near-line (power/usage managed HD) is somewhat of an option (especially when not sending everything to tape, which is a good strategy today). > I can't imagine why the original poster is using the 3Ware card > as a "dumb" IDE controller. That makes *zero* sense. Well, he did say something I didn't think of, there was no real hot-swap support except for with a 3Ware card. But I want to say that RAIDCore (typically 8-channel ATA PCI cards that use their own FRAID driver(s)) also has hot-swap too. > It's at least as reliable (and maybe moreso) than the Linux software > RAID bits (which is also pretty darned reliable). Other than the 3Ware 6000 series, I have _never_ heard of an issue with RAID-5. -- Bryan J.

Any tax rate that penalizes them will also penalize you similarly (to those below you, and then below them). Linear algebra, let alone differential calculus or even ele- mentary concepts of limits, is mutually exclusive with US journalism. So forget even attempting to explain how tax cuts work. ;->
