Thanks for the suggestions. I'll have a look at some of them and see
if I can figure something out.

I don't mind manually making lists of files as I start working with
them. What really prompted this was that I have some home automation
working really well on an old server I had. One power outtage that
lasted longer than 30 minutes while I was away from home, two hard
drives in the array went offline. I thought the whole server was lost
and last night I dusted it off and rooted around in the adaptec
interface and was able to force them both back online and bring the
array back up. I quickly copied off my heyu files but I got to
thinking if there was a way to automatically rsync files somewhere
when I edit them, it would make things simpler on a server I have no
need to completely back up, yet have some good info on it.

I'm a sloppy person, so I set up an rsync-based solution derived from a
script I snagged through googling.  It keeps 4-hourly, daily, 4 weekly,
and several monthly rotating backups of the directories I list.  Let me
know if you want it.  Sometime I'll clean it up some more and put it on
my web site.

Something that we do to get most of the configuration files backed up is:

# Create list of RPM config files that have changed
> files_rpmconfig
rpm -qac --dump  | sed -e "/^(/d" | while read -a line
do
#	echo "Line: ${line[0]} ${line[3]}"
	if false
	then
		if [ ! -r ${line[0]} ]
		then
			echo "Unable to access file: ${line[0]}"
		fi
	fi
	if [ -f ${line[0]} ]
	then
		fi=(`md5sum ${line[0]}`)
#		echo "Sum: ${fi[0]}"
		if [ ${fi[0]} != ${line[3]} ]
		then
			echo "${line[0]}" >> files_rpmconfig
		fi
	fi
done

have to add any configuration files for those manually. We normally do this
during OS updates so we can quickly look back at configuration changes without
having to go and get the full backup disk.
