Here is a script that I found that has been working well for me. I set up a
cron job to run this file every night just after midnight. It e-mails a
gzipped sql dump file as an attachment to the specified e-mail address.
Right now the database this is backing up is not very big. I'm not sure how
scalable it is (probably not very).
Suggestions/improvements are welcome.
<?php
set_time_limit(0);
ini_set("memory_limit", "500M");
$dbhost = 'localhost';
$dbuser = 'username';
$dbpass = 'password';
$dbname = 'database';
$backupDir = '/backups/';
$backupFileName = $dbname . date("Y-m-d-H-i-s") . '.sql.gz';
$backupFile = $backupDir . $backupFileName;
$command = "mysqldump -u $dbuser -p$dbpass $dbname | gzip >
$backupFile";
system($command);
$email_from = "[EMAIL PROTECTED]"; // Who the email is from
$email_subject = "MySQL Backup ".date("m/d/Y", time()); // The
Subject of the email
$email_txt = "Your file is attached."; // Message that the email has
in it
$email_to = "[EMAIL PROTECTED]"; // Who the email is to
$headers = "From: ".$email_from;
$file = fopen($backupFile,'rb');
$data = fread($file,filesize($backupFile));
fclose($file);
$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\"";
$email_message .= "This is a multi-part message in MIME format.\n\n"
.
"--{$mime_boundary}\n" .
"Content-Type:text/html;
charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$email_txt . "\n\n";
$data = chunk_split(base64_encode($data));
$email_message .= "--{$mime_boundary}\n" .
"Content-Type:
application/octet-stream;\n" .
" name=\"{$backupFileName}\"\n" .
"Content-Transfer-Encoding:
base64\n\n" .
$data . "\n\n" .
"--{$mime_boundary}--\n";
$ok = @mail($email_to, $email_subject, $email_message, $headers);
if($ok) {
echo date("Y-m-d H:i:s") . " Operation completed.\n";
} else {
die(date("Y-m-d H:i:s") . " Operation failed - The e-mail could not
be sent.\n");
}
