=head1 PROGRAM NAME AND AUTHOR
MySQL Backup v3.3
by Peter Falkenberg Brown
peterbrown@worldcommunity.com
http://worldcommunity.com/opensource/
Build Date: September 14, 2008
=PURPOSE
Backs up mysql data safely, using
'mysqldump', 'select to outfile' or 'normal record selection'.
This is my attempt :-) to provide a reasonably
full featured MySQL backup script that can be
run from:
1. Linux Crontab or Windows Scheduler
2. the shell or command prompt
3. the web (with password protection)
(Note that I don't recommend running it from the web
because of permission issues - however, some users
don't have shell access. It depends upon the security
level of your data.
It now works from both Linux and Windows.
See URLs at the end about where to get
WINDOWS VERSION OF UNIX UTILITIES.
It provides options to backup all of the databases and tables
in one particular host, with exception lists.
It now has the ability to select a variety of options
for the tar and gzip functions, including using the
tar -z switch, using bzip2 and piping data through gzip/bzip2.
It also deletes text files in between tar and gzip, to save space.
It also works around the sql wildcard glitch with
underlines (_), in table names, by not using mysqlshow
to get table names. I did this, because mysqlshow db %
didn't work under MySQL v3.22.20a, and I wasn't able to
determine when the % method came into being (under which
version.) So, in order to make things work for earlier
versions, I used 'show tables'.
(I still use mysqlshow for database names.)

# Because the login must test the mysql authorization
# against a specific database, this new variable
# is required **ONLY** when logging in from the web.
# Use the name of ANY database for which your
# login username has authorized access.
# NOTE! This database name has NO relationship to the
# -- @selected_databases and
# --$process_all_databases variables
# You still MUST set those variables correctly.
# The $web_test_database var is ONLY used
# for an initial login test.
# NOTE! The user must be authorized for the
# test database AND the database that you place
# in the selected_database array
# If the user is NOT authorized for both,
# the script might pass the first login test,
# but fail on the specific database login,
# which would happen AFTER the creation of the
# backup directory (which is messy).
@selected_databases = qw[];
# place the names of your databases here,
# separated by spaces, or set
# process_all_databases to 'yes'
$process_all_databases = 'yes';
# @selected_databases is ignored if you set
# process_all_databases to 'yes'
# Many servers with virtual hosts allow you
# to see all of the databases while only giving
# you access to your own database. In that case,
# place the name of your database in the
# @selected_databases array.
# Someone else might want to process all of the
# databases, with possible exceptions. If so,
# place the databases to skip in the
# skip_databases array below.
@skip_databases = qw[];
# Note: skip_databases is only parsed
# if process_all_databases is set to 'yes'
# Leave it blank if you don't want to use it., i.e:
# qw[];
@skip_tables = qw[];
# skip_tables is always parsed.
# Leave it blank if you don't want to use it., i.e:
# qw[];
# This may be an issue with duplicate table names
# in multiple databases -- it's on the todo list.
$password_location = 'cnf';
# NEW OPTION FOR PASSWORD LOCATION:
# 'from_web' ALLOWS WEB LOGIN
#.................................................
# set to 'cnf' or 'this_file' or 'from_web'
#.................................................
# NOTE!! I have NOT tested cnf under Windows.
#.................................................
# the connection subroutine uses this
# to decide which method to use.
# I've added functionality that allows the script
# to be run from the web, because some users
# don't have shell access.
# if $password_location is set to 'from_web',
# then n chars are translated to
and also, a
# "Content-type: text/htmlnn"; is printed to sdtout.
# note that you'll have to either run the
# .cgi file from your web tree, or use a 'stub' file
# which I recommend. (see my web page for an example).
# NOTE!!! RUNNING FROM THE WEB is predicated
# on a number of issues:
# - web logins don't use a cnf file, since
# the cnf file would be required to be world
# readable, and because we have to check
# the user login anyway, against mysql.
# - the backup directory ($mysql_backup_dir)
# must be writeable by the web server
# (since it's outside the webtree and the
# the script requires a login, the risk
# is controlled -- however, if your server
# co-exists with other virtual servers,
# you should make sure that they can't ftp
# outside their own home directory.)
# - set $chmod_backup_file to 'no'
# since files will be owned by web server
# and if they're set to 600 you won't be able
# to download them
# - depending on which user you login as
# (super user or single user)
# you may not have permission to
# backup databases other than your own;
# thus, set
# -- @selected_databases and
# --$process_all_databases correctly.
# - mysql user permissions will also influence
# whether or not you can use
# the 'select into outfile' method of backup
# -- try myslqdump...
# -- if all else fails, use 'normal_select'
# - Note about SSL and Web logins:
# If you've got an ssl url, use it!
# It's worth it to encrypt your database
# username and password.
# (Just run the script prefixed by
# https://yourdomain.com/script_name.cgi)
# SSL Note2: Even if you don't OWN an SSL Cert,
# you can often use the https ssl syntax;
# the web server will encrypt it anyway;
# it simply warns you that you don't have
# an ssl cert. What do you care :-)?
# (You're the one running the script.)
# The Cert/Browser marriage is a SCAM
# in my opinion. Since the encryption
# happens anyway, the stupid warning box
# should be eliminated. Maybe a Congressional
# sub-committee should investigate it :-).
# If you want a CHEAP, FAST, cert, go to:
# http://instantssl.com (approx. $40!)
$login_script_name = 'mysql_backup_login.cgi';
# this is the name of the script that's used
# for web login -- either the real script,
# or a stub script
# If you're not using the web option,
# you can keep it blank, or whatever.
# See our website for an example stub script.
$chmod_backup_file = 'yes';
# set to 'yes' if you want to use it
# (you DO NOT want to set the backup file to 600

# set $db_host to a remote server if you need to access data
# on a different machine.

# but you should set this to 700 (rwx------)
# so that it's more secure.
# we assume here that your user name status
# equals the functions needed.
# (for example, 'select to outfile'
# requires file privileges.)
# NEW IN V3.0!
# I now longer parse the cnf file manually.
# (I actually didn't use the parsed data
# in 2.7, but I hadn't deleted the code.)
# If you select cnf_file, mysqlshow and mysqldump
# will use the cnf_group variable

# 1: When you have multiple instances of the
# MySQL daemon running on your host,
# where each instance of the daemon
# has its own mysql.sock file - Therefore
# the script needs to find the socket file.
# 2: If your MySQL socket file is NOT
# in a default directory, such as:
# /var/lib/mysql/mysql.sock
# then you may need to use the above
# environment command.
# If you use the normal MySQL
# installation, you can COMMENT OUT the above line
