# start a counter for any errors

# to exclude any directory from the tar file create CACHEDIR.TAG with a single line 'Signature: 8a477f597d28d172789f06886806bc55'
# this is used by --exclude-caches-under to exclude all files and folders from which the CACHEDIR.TAG file exists
tar --exclude-caches-under --exclude-vcs-ignores -cjf /backups/home.tar.bz2 -C / home/

# exit using the combined total of any errors
