Generally, backing up a database on a VM is troublesome. For convenience, I wrote a simple method for backing up MYSQL databases.
PHP code:
/**
* VM Backup Program
* Programming: Boban
* Discussion: http://www.21php.com/forums/
* Updated: 2004-02-02
* Instructions
* 1. change the MYSQL connection parameters, $ dbuser, $ dbpass, $ dbname
* 2. log on via FTP and create a dedicated directory for backup data. change the attribute to 777.
* 3. access this program through a browser. if the path of mysqldump is incorrect, change it by yourself (default:/usr/bin/mysqldump)

Set_time_limit (900 );
$ Today = date ("_ Y_m_d ");
$ Dbuser = "root ";
$ Dbpass = "";
$ Dbname = "www_21php_com ";
$ Servername = $ _ SERVER ['server _ name'];
$ Servername = str_replace ('.', '_', $ servername );
// Echo $ servername;
$ Docroot = getcwd ();
Echo system ("locate mysqldump ");
Echo"
";
// Delete the backup file
System ("rm./*. gz ");
System ("rm./*. SQL ");
// Start backup
System ("/usr/bin/mysqldump -- opt $ dbname -- user = '$ dbuser' -- password =' $ dbpass'> '. /$ servername $ today. SQL '", $ r1 );
If ($ r1 = 0) echo "MYSQL data backup successful
";
Else echo "backup failed
";
System ("gzip./$ servername $ today. SQL", $ r2 );
If ($ r2 = 0) echo "MYSQL data is compressed successfully.
";
Else echo "backup failed
";
System ("tar-czf'./your servername=today.tar.gz'' $ docroot/../'", $ r3 );
If ($ r3 = 0) echo "website ($ docroot) backup successful
";
Else echo "backup ($ docroot) failed
";
?>
