OT a bit, but FreeBSD or Solaris?  Are you happy with the stability of the 
whole kit and kaboodle?

That I'm OK with.  What I hate is any type of perl or shell script that 
has to deal with days, weeks, months and years.  I've got a serious mental 
block on that stuff.. Most of my time hacking this mess together will be 
looking for perl modules I imagine.

I am finding a TON of "rolling snapshot" scripts, but I really want to 
come closer to emulating a good old-fashioned backup setup that lets me 
keep X yearly, Y monthly, Z weekly and ZZ daily sets of backups.  Gnash 
gnash gnash.
