Thank you for looking at the archives first.  Honestly, thanks :-)

Note that there is no /backupvar mount point listed above...

The second command will attempt to synchronise /var with /backupvar
and effectively create a copy of the entire /var partition in your
root filesystem.  Since /dev/ad0s1e (your /var partition) is larger
than /dev/ad0s1a (the root partition) this will quickly fill the root
partition to 100% and start grabbing blocks from the "reserved space"
(the default is 8% of the partition).  You are running this as root
and FreeBSD doesn't block you at 100% but goes on merrily with its job
until both the partition and the reserved space are full
(100 + 8 = 108%; this is why the usage percentage in / is listed as
107% and not as 100%).

You're welcome :)
