As has been mentioned, if you have critical or irreplaceable data, back 
it up.    If your partitions are too large for any backup system you
can use, then make a scheme for breaking the data in to more manageable
sized partitions - use more partitions and even more slices and disk
devices if needed.   Those huge raid partitions are nice for some
things, but have their drawbacks.   

You can get backup devices - LTO and high end DLT that hold up to 160
or more uncompressed, so that is a good single sized partition.  They
are expensive, but not compared to losing your data.

Also, you are supposed to be able to use more than one tape in a backup.
I don't know how well that works in FreeBSD dump/restore.  I don't have
a big enough disk under FreeBSD to make it go to more than one tape yet.
But, I have successfully dumped partitions that needed up to 10 DAT tapes
before on other UNIX systems.
