Here is the easiest way to backup your web server with Drobox.Most of you guys have trouble setting up a secure backup option, Backing up the files to the same saver where it is hosted is again not a reliable option, You may also have space constrains. Lets see how dropbox can sort out the backup easily.
Requirements
- Cpanel Access to your Server and Cron Job Module
- Dropbox Api
- PHP and Curl Support in the server you are going to implement this.
Lets divide the entire backup process into 3 functions
- Backu Database
- Backup files
- Upload it to dropbox.
Backup Database
There are hundreds of database backup scripts available in the Internet, you can use any of them but here I am going to use this code that I feel is more reliable and its taken from David Walsh’s blog I have slightly modified the script to optimize it
function backup_db($host,$user,$pass,$name,$dbFile,$tables = '*'){
$link = mysql_connect($host,$user,$pass);
mysql_select_db($name,$link);
//get all of the tables
if($tables == '*')
{
$tables = array();
$result = mysql_query('SHOW TABLES');
while($row = mysql_fetch_row($result))
{
$tables[] = $row[0];
}
}
else
{
$tables = is_array($tables) ? $tables : explode(',',$tables);
}
//cycle through
$return = '';
foreach($tables as $table)
{
$result = mysql_query('SELECT * FROM '.$table);
$num_fields = mysql_num_fields($result);
$return.= 'DROP TABLE IF EXISTS '.$table.';';
$row2 = mysql_fetch_row(mysql_query('SHOW CREATE TABLE '.$table));
$return.= "\n\n".$row2[1].";\n\n";
for ($i = 0; $i < $num_fields; $i++)
{
while($row = mysql_fetch_row($result))
{
$return.= 'INSERT INTO '.$table.' VALUES(';
for($j=0; $j < $num_fields; $j++)
{
$row[$j] = addslashes($row[$j]);
$row[$j] = ereg_replace("\n","\\n",$row[$j]);
if (isset($row[$j])) { $return.= '"'.$row[$j].'"' ; } else { $return.= '""'; }
if ($j < ($num_fields-1)) { $return.= ','; }
}
$return.= ");\n";
}
}
$return.="\n\n\n";
}
//save file
$handle = fopen($dbFile,'w+');
fwrite($handle,$return);
fclose($handle);
echo " Database Backup File Created : ".$dbFile."\n";
}
Backup Server Files
Lets assume that you have your files under /home/YourPath/public_html/
function backupFiles($siteZipFile){
shell_exec("tar -cvf ".$GLOBALS['siteZipFile']." /home/YourPath/public_html/* ");
echo " Files Backup File Created : ".$siteZipFile." \n";
}We are just selecting all the files under the public_html folder and creating an archive.
Drobox API Code for Backup
Now lets create the dropbox function to upload the files to dropbox
function pushToDropbox($file_path_str){
{
$url_path_str = 'https://api-content.dropbox.com/1/files_put/auto/Foldername/'.$file_path_str;
$header = array(
"Authorization:Bearer _YourAccessToken_",
"Content-Length:".filesize($file_path_str)
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url_path_str);
curl_setopt($ch, CURLOPT_PUT, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
$fh_res = fopen($file_path_str, 'r');
$file_data_str = fread($fh_res, filesize($file_path_str));
rewind($fh_res);
curl_setopt($ch, CURLOPT_INFILE, $fh_res);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($file_path_str));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$curl_response_res = curl_exec ($ch);
echo $curl_response_res; // Server response
print_r(curl_getinfo($ch)); // Http Response
curl_close($ch);
fclose($fh_res);
}Now Lets conclude to get the Final Code
Final Code
function backup_db($host,$user,$pass,$name,$dbFile,$tables = '*'){
$link = mysql_connect($host,$user,$pass);
mysql_select_db($name,$link);
//get all of the tables
if($tables == '*')
{
$tables = array();
$result = mysql_query('SHOW TABLES');
while($row = mysql_fetch_row($result))
{
$tables[] = $row[0];
}
}
else
{
$tables = is_array($tables) ? $tables : explode(',',$tables);
}
//cycle through
$return = '';
foreach($tables as $table)
{
$result = mysql_query('SELECT * FROM '.$table);
$num_fields = mysql_num_fields($result);
$return.= 'DROP TABLE IF EXISTS '.$table.';';
$row2 = mysql_fetch_row(mysql_query('SHOW CREATE TABLE '.$table));
$return.= "\n\n".$row2[1].";\n\n";
for ($i = 0; $i < $num_fields; $i++)
{
while($row = mysql_fetch_row($result))
{
$return.= 'INSERT INTO '.$table.' VALUES(';
for($j=0; $j < $num_fields; $j++)
{
$row[$j] = addslashes($row[$j]);
$row[$j] = ereg_replace("\n","\\n",$row[$j]);
if (isset($row[$j])) { $return.= '"'.$row[$j].'"' ; } else { $return.= '""'; }
if ($j < ($num_fields-1)) { $return.= ','; }
}
$return.= ");\n";
}
}
$return.="\n\n\n";
}
//save file
$handle = fopen($dbFile,'w+');
fwrite($handle,$return);
fclose($handle);
echo " Database Backup File Created : ".$dbFile."\n";
}
function backupFiles($siteZipFile){
shell_exec("tar -cvf ".$GLOBALS['siteZipFile']." /home/YourPath/public_html/* ");
echo " Files Backup File Created : ".$siteZipFile." \n";
}
function pushToDropbox($file_path_str){
{
$url_path_str = 'https://api-content.dropbox.com/1/files_put/auto/Foldername/'.$file_path_str;
$header = array(
"Authorization:Bearer _YourAccessToken_",
"Content-Length:".filesize($file_path_str)
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url_path_str);
curl_setopt($ch, CURLOPT_PUT, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
$fh_res = fopen($file_path_str, 'r');
$file_data_str = fread($fh_res, filesize($file_path_str));
rewind($fh_res);
curl_setopt($ch, CURLOPT_INFILE, $fh_res);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($file_path_str));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$curl_response_res = curl_exec ($ch);
echo $curl_response_res; // Server response
print_r(curl_getinfo($ch)); // Http Response
curl_close($ch);
fclose($fh_res);
}
$siteZipFile = "site_backup_".date('m_d_Y', time()).".tar.gz"; // Set the Current date in file Name
$dbFile = 'db-backup-'.date('m_d_Y', time()).'.sql'; // Set the Current date in file Name
backup_tables('localhost','dbUser','dbPwd','daName');
backupFiles($siteZipFile);
pushToDropbox($dbFile);
pushToDropbox($siteZipFile);Setting up the Cron Job
- Lets name the script that you have created as “serverBackupDropbox.php”
- Create a folder outside your public_html folder , lets name it “backup” and place the backup script inside this folder. lets assume that the file path is now “php home/backup/serverBackupDropbox.php”
- Navigate to Cron module in your Cpanel and add the following command, and set your desired Cron interval.
php home/backup/serverBackupDropbox.php
You quick and easy drop-box backup solution is ready.
