It isn't: what you want is to write to two disks at once. But if the software wasn't designed for that, that's problems all the way to the catalog. The other problem is that rsyncing an umpteen-TB drive can take a non-trivial amount of time and ram. -- Dimitri Maziuk Programmer/sysadmin BioMagResBank, UW-Madison -- http://www.bmrb.wisc.edu
