[SunHELP] Online Backup of a mirrorred root partition

[Hichael Morton]

sun's bigadmin has a number of scripts.  one clones a drive slice by 
slice.  it works great and we have used it for over a year.  you will 
need to change the original/clone hard drive information but this is no 
big deal.  (you don't want to overwrite the original.)
