Yes, RAID 1 is mirroring and you can do it in software.  Check the
HOWTOs at www.linuxdoc.org related to this.

However keep in mind this protects only against drive failure.  There
are plenty of other ways to hose your data, and it's certainly no
substitute for doing backups.

mirror the SCSI data disk like NT mirroring.  This, of course, is
because I was not authorized to purchase RAID which is what we need. 
Anyway, how would I accomplish "NT like" disk mirroring in linux.  I
have a few ideas on the matter but I hope some of you have experience
with this.  Should I just setup software raid?  Thanks.  I will carry
this question to the meeting tonight so look for a big tall goon in a
blue shirt and white shorts if you have comments on this.
