Backup database

[donato.sciarra]

Salve ragazzi, ho necessita di creare backup periodici.
Esiste una query che lanciata raccolga tutte le informazioni con relativi tipi di dato e salvi il tutto in un file .sql?

grazie a quanti mi aiuteranno.


P.S.
non ho necessità di copiare i dati in un altro database ma fare un esportazione come qnd in phpmyadmin si esporta un database.

Questo script ti interesserà molto. =)

// configure your database variables below:
$dbhost = 'localhost'; // Server address of your MySQL Server
$dbuser = 'your_username'; // Username to access MySQL database
$dbpass = 'yourpass'; // Password to access MySQL database
$dbname = 'database_name'; // Database Name

// Optional Options You May Optionally Configure

$use_gzip = "yes";  // Set to No if you don't want the files sent in .gz format
$remove_sql_file = "yes"; // Set this to yes if you want to remove the .sql file after gzipping. Yes is recommended.
$remove_gzip_file = "no"; // Set this to yes if you want to delete the gzip file also. I recommend leaving it to "no"
 
// Configure the path that this script resides on your server.

$savepath = "/www/htdocs/dbsender"; // Full path to this directory. Do not use trailing slash!

$send_email = "yes";  // Do you want this database backup sent to your email? Fill out the next 2 lines
$to      = "you@yourdomain.com";  // Who to send the emails to
$from    = "r00t@yourdomain.com"; // Who should the emails be sent from?

$senddate = date("j F Y");

$subject = "MySQL Database Backup - $senddate"; // Subject in the email to be sent.
$message = "Your MySQL database has been backed up and is attached to this email"; // Brief Message.

Salve a tutti.
lo script gira e non da errori, l'unica cosa è che mi produce un file vuoto!

Dove sto sbagliando?
