Oh, yes, I've forgotten to mention this. By default, if tar encounters a
directory in the file list, it will recursively descend to this
directory and back up its contents. So, if you simply pipe the find
output to tar, you'll get each file added twice. To avoid this, use
--no-recursion option to tar. So, the corrected invocation from my
previous post will be: 


find $filesys -mount $SKIPSTRING -print |
tee $LISTFILE |
tar --rsh-command=/usr/bin/ssh \
    --one-file-system \
    -c -z -f $BU_HOST:/backups/$MYHOST/$DAY/$c_filesys.cpio.gz \
    -P -T - \
    --no-recursion \ 
    $filesys

Tar archives every file or directory name it is given, no matter what its
contents is.
