A simpler way:
tar up all the files from september in $logdir
create two dummy files with dates
201209010000 beginning of September
201209305959 end of september
Code:
cd $logdir
touch -t 201209010000  /tmp/d1
touch -t 201209010000  /tmp/d2
# back the files we want
tar -cfv /tmp/mytarball.tar $(find . \( -newer /tmp/d1 -a ! -newer /tmp/d2 \) )
if [ $? -ne 0 ] ; then
   echo "tar failed"
   exit 1
fi
# the above traps all tar failures
# do something here to check read the tar file  I do not know what you want
# We could restore the tarball someplace and do a directory compare maybe

gzip /tmp/mytarball.tar 
# /tmp is not good longer term storage

mv /tmp/mytarball.tar.gz /someplace/safe
# delete the files
find . \( -newer /tmp/d1 -a ! -newer /tmp/d2 \) -exec rm {} \;

virt-tar-out(1) 					      Virtualization Support						   virt-tar-out(1)

NAME
virt-tar-out - Pack a virtual machine disk image directory into a tarball. SYNOPSIS
virt-tar-out -a disk.img /dir files.tar virt-tar-out -d domain /dir files.tar virt-tar-out -d domain /dir - | gzip --best > files.tar.gz DESCRIPTION
"virt-tar-out" packs a virtual machine disk image directory into a tarball. The first parameter is the absolute path of the virtual machine directory. The second parameter is the tar file to write. Use "-" to write to standard output. EXAMPLES
Download the home directories from a guest: virt-tar-out -d MyGuest /home - | gzip --best > homes.tar.gz JUST A SHELL SCRIPT WRAPPER AROUND GUESTFISH
This command is just a simple shell script wrapper around the guestfish(1) "tar-out" command. For anything more complex than a trivial copy, you are probably better off using guestfish directly. OPTIONS
Since the shell script just passes options straight to guestfish, read guestfish(1) to see the full list of options. SEE ALSO
