In phpMyAdmin, there is an option to export the entire table (or database) into a .SQL file.
I cannot work out how they do this - as I want to stick it into a CRON job to make daily and weekly backups of databases. But there doesn't seem to be any single command that does it - is there?
You can run these commands with PHP, copy the following piece of code into a file and execute it with cron job.
<?php
//Backup:
//ENTER THE RELEVANT INFO BELOW
$mysqlDatabaseName ='databasename';
$mysqlUserName ='username';
$mysqlPassword ='password';
$mysqlHostName ='localhost';
//$mysqlExportPath ='database.sql';
$mysqlImportFilename ='myownsit_obsolcms.sql';
//DONT EDIT BELOW THIS LINE
//Export the database and output the status to the page
$command='mysql -h' .$mysqlHostName .' -u' .$mysqlUserName .' -p' .$mysqlPassword .' ' .$mysqlDatabaseName .' < ' .$mysqlImportFilename;
exec($command,$output=array(),$worked);
switch($worked){
case 0:
echo 'Import file <b>' .$mysqlImportFilename .'</b> successfully imported to database <b>' .$mysqlDatabaseName .'</b>';
break;
case 1:
echo 'There was an error during import. Please make sure the import file is saved in the same folder as this script and check your values:<br/><br/><table><tr><td>MySQL Database Name:</td><td><b>' .$mysqlDatabaseName .'</b></td></tr><tr><td>MySQL User Name:</td><td><b>' .$mysqlUserName .'</b></td></tr><tr><td>MySQL Password:</td><td><b>NOTSHOWN</b></td></tr><tr><td>MySQL Host Name:</td><td><b>' .$mysqlHostName .'</b></td></tr><tr><td>MySQL Import Filename:</td><td><b>' .$mysqlImportFilename .'</b></td></tr></table>';
break;
}
//Restore:
$mysqlExportPath ='path_to_file/database.sql';
//DONT EDIT BELOW THIS LINE
//Export the database and output the status to the page

//$command = "$ mysqldump -u $mysqlUserName -p $mysqlPassword $mysqlDatabaseName > myownsit_obsolcms.sql";
exec($command,$output=array(),$worked);
switch($worked){
case 0:
//echo 'Database <b>' .$mysqlDatabaseName .'</b> successfully exported to <b>~/' .$mysqlExportPath .'</b>';
break;
case 1:
echo 'There was a warning during the export of <b>' .$mysqlDatabaseName .'</b> to <b>~/' .$mysqlExportPath .'</b>';
break;
case 2:
echo 'There was an error during export. Please check your values:<br/><br/><table><tr><td>MySQL Database Name:</td><td><b>' .$mysqlDatabaseName .'</b></td></tr><tr><td>MySQL User Name:</td><td><b>' .$mysqlUserName .'</b></td></tr><tr><td>MySQL Password:</td><td><b>NOTSHOWN</b></td></tr><tr><td>MySQL Host Name:</td><td><b>' .$mysqlHostName .'</b></td></tr></table>';
break;
}

Yeah, mysqldump: http://linuxcommand.org/man_pages/mysqldump1.html
You'll need to have server access to use it though. Also, if you're feeling adventurous and want to maintain consistent backups look up information on master/slave setups.
use mysqldump
mysqldump -h hostname -u user -pPassword dbname >/path/to/file
host is optional if host is localhost. depending on some settings user and password may be optional as well. Note you may want to add the date name
mysqldump -h hostname -u root mydb > /path/to/backup/$(date +%a)
mysqldumpwith the right parameters.
