About 30 are active, 12 are sporadic (laptops, etc).  Total that gets 
written out to off site backup is about 300GB of data a day, compressed.

No.  Default options for Debian etch.  This filesystem has been 
xfs_growfs'd a few times after being dd'd to a new volume, since it's 
impossible to back it up with xfsdump|xfsrestore.  I mount with noatime, 
and logbufs=8

6.4TB, and 2.8TB is in use, with 2TB or so of that being backuppc's.
