# Virtualhost backup script [Thomas Lange <code@nerdmind.de>] #
#%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%#
# #
# This script goes through the first level in the virtual host root directory #
# and creates for each domain name within a compressed backup file. The script #
# is compatible with a directory structure like the following: #
# #
# |--- bob #
# | |--- bobs-blog.tld #
# | |--- config #
# | |--- htdocs #
# |--- alice #
# | |--- alice-domain.tld #
# | |--- config #
# | |--- htdocs #
# |--- thomas #
# |--- sub1.thomas-blog.tld #
# | |--- config #
# | |--- htdocs #
# |--- sub2.thomas-blog.tld #
# |--- config #
# |--- htdocs #
# #
# OPTION [-q]: Enable quiet mode for use in crontab. #
