This is probably not the most elegant way of doing things, but I think this
will work until your enhancement request is granted! Basically build 2
filelists, sort them together and show only the unique entries that reside
on the client.
#!/bin/sh
#
# Compares TSM filespace to actual filespace
# Displays client files not backed up on TSM
#
# Usage
# tsmcomp.sh /home/\*
#
echo "Preparing filelist from TSM for $1"
dsmc q backup -subdir=y "$1" | awk 'NR>11 {print "T "
substr($0,index($0,$7))}' > /tmp/tsm.out
echo "Preparing filelist on client for $1"
find $1 -printf "C %p\n" > /tmp/client.out
echo "Comparing filelists..."
sort -k 2 /tmp/tsm.out /tmp/client.out | uniq -u -f 1 | grep '^C' | cut -c

I am looking for something more than a -mtime. My concern is a mistake in
the dsm.opt/dsm.sys/inclexcl.list that creates a situation where only
directories are backedup and no files in those directories. I'm not asking
for a list of files that should be backed up now, though I really like that
idea (-preview), what I'm looking for is a set subtraction. Take a list of
all files in the live filesystems, subtract the set of all files within the
TSM repository, then give me the results. I'll look at the results and see
if they are 'resonable' not to be in tsm, or decide that I need to modify my
inclexcl.list, etc.
