Please make sure of the following before you configure the script:

• The user that is running the script must have execute permissions on cscript in system32
• The user that is running the script must have write permissions folder that is going to store the backup file.
• The user that is running the script must have execute permissions on mysqldump.exe in Mysqlbin
• If you running this script in browser then your web user will need the above permissions.

So here is the script:

backup-mysql-database.vbs

Option Explicit
Dim backup_dir, num_days, user, password, database, arguments, backup_file
Dim oShell, oFS, oDrive, nResults, sqldump

backup_dir = "C:MysqlBackups"
user = "xxxxxxxx"
password = "yyyyyyyy"
database = "zzzzzzzz"
sqldump = "C:Mysqlbinmysqldump.exe"

backup_file = backup_dir & database & ".sql"
arguments = "--user=" & user & " --password=" & password & " " & database & " > " & backup_file
arguments = sqldump & " " & arguments
WScript.Echo(arguments1)

Set oShell = CreateObject("WScript.Shell")

WScript.Echo("Creating backup file " & backup_file)
nResults = oShell.Run ("cmd /C" & arguments, 1, TRUE)
WScript.Echo(nResults)

Set oShell = Nothing

The following variable will be needed to be defined as per your need:

backup_dir = Should have the path to the directory that you want to save you backup file in.
user = Database user name that has full privileges over the database you want to backup.
password = Password of the database user.
database = Name of the database that you want to backup
sqldump = Path to mysqldump.exe, normally this is stored in MySQLbin directory.

To backup all database you can ignore the database variable and replace the first argument command with:

arguments = "--user=" & user & " --password=" & password & " --all-databases --quick
--result-file=" & backup_file

Now you can run the command below to execute the script on Windows server:

cscript c:myscriptsbackup-mysql-database.vbs

You can also schedule the above command to run on sceduled timining to backup the MySQL databases.

Large MySQL Backups:

Error: MySQL has gone away

To restore large SQL backups there are 2 setting that you will need to take of:

1. Make sure that you PHP upload size is great than your MySQL backup file, this setting will be needed to be changed in php.ini file. Only those who has server administrator access would be able to make changes in PHP.INI file. Hence you will have to contact your Hosting provider if you are hosted on a Shared server. But if you have a Dedicated Server then this file is normally stored in C:\Windows\php.ini or you can esily get the path from phpinfo() page. The option that you need to change is upload_max_filesize. It is also suggested that you increase the following parameters as per the size of your MySQL backup file:

max_execution_time = 30     ; Maximum execution time of each script, in seconds
max_input_time = 60    ; Maximum amount of time each script may spend parsing request data
memory_limit = 8M      ; Maximum amount of memory a script may consume (8MB)

2. You will need to increase the MySQL buffer size in MySQL configuration size, the file is my.cnf in Linux server and my.ini on Windows Server. The parameter that you need to change is:

read_buffer_size

By default it is set to 1MB, if the entry is not present then add it under [MYSQLD] section.

Please Make sure that you restart IIS webserver after making change to php.ini and restart MySQL after making changes in my.ini file.
