I've had a few drive failures but they never really hurt much.
Tradestation 2000i can kill your data all by itself if you are
careless. My offsite backup is to CD and now more recently DVD.
Takes a long time to backup 10+ gig but if you have it then all you
need is data from that backup on. I wont get into all the detail but
it works well. Data problems were much more frequent with DTN
Satellite than with Esignal. Plus you can get fill in data for at
least 90 days from Esignal via download. That basically solved my
problems with data. Now I rarely do a Casper backup but I do allow
nightly XP backups of data for 5 trading days. Plus I backup other
junk like documents and email. I have all programs on CD and also on
the backup drive. The install programs that is. Works for me and I
don't have to have RAID 5 or any raid actually but I do think it is a
good thing to have if it rings your bell or fits your situation.

So what you're really dealing with is the fear and reality of corrupted
data-that's of course different to providing for hardware failure.
Offsite/bup that stores several iterations really is the solution. For
example, on my laptop I keep changed files upto 6 months of age. That is, if
I need a version of an ini file or the registry that's 170 days ago, I can
quickly find it.
I'd argue strongly that gigs of data is much of an issue. Another example,
at 200mbit/s, which is a pretty slow connection, it takes about 5 hours to
move 2gb (each night). Are you changing more than that each day? Probably
not.
Again, you can automate restore points as frequently as you like. If you
need to rollback, do so, off-load the recovered
folders/files/registry/whatever to a temp folder, roll forward (reinstate
the retore point), re-load the recovered folders/files/registry/whatever
from the temp folder. Simple!

I pretty much only deal with loosing my data when I think backup.
RAID is great for a drive failure but not useful if your data gets messed
up. I've had corrupted data too many times in the past so RAID is little
help, it works too fast. Offsite bup wont work for some of us as we have
too much data to export. Restore points are great but pretty much every
time I use them I loose something, but usually the loss is not real
important. Viruses and worms have never been a problem for me.

Yuk!
Jimmy, with RAID 0, if a drive fails, all you have to do is swap it for a
new drive without turning off the PC. This you conceptually know, right. No
rebooting, cloning, etc. It couldn't be easier.
If a virus has corrupted anything, which seems to be a rationalization for
doing images from which to recover, you have 2 choices if you can't manually
fix the corruption. From offsite bup restore the corrupted folder or
registry, or restore to XP's last restore-point. Either way takes 2-3
minutes. With offsite bup you can go back several iterations if necessary.
These are no-brainers. No swapping cables or disks etc.
Respectfully of course, I'm still at a loss as to why anyone would want to
do it the hard way! Btw there are tools that'll do restore points
periodically or whenever there's a change to the registry.

If you really want to test your brain use BOTH. With Serial ATA drives you
can have RAID. Then you can have a ATA or serial drive in addition to the
two serial ATA drives back up on.
I didn't use RAID but did use two Serial ATA drives that Casper cloned one
to the other. Then I also had a bootable IDE type ATA drive that had
everything on it including a nightly backup using Windows XP's shadow
backup. The beauty of this is you can, depending on your BIOS options, boot
to the IDE drive instead of the Serial ATA drives by simply making a change
in the BIOS during your reboot.
Sorry to complicate things,
Jimmy
Thanks for all the advice. Will consider RAID but probably will go with
Casper.
