Transfer FTP Files Directly From One Server to Another

Transfer FTP Files Directly From One Server to Another and Bypass the Huge Amount of Time Required to Download on Your Computer and Upload. As we said for DNS Setup for Rackspace Cloud Sites to Cloud Server Migration and in Rackspace Cloud Sites to Cloud Server Migration Guide like articles, transfer of files for migration reasons is quite important.

If you want to deal in complicated situation, you can use Hostgator like B Grade Webhosting for dumping purpose, they practically costs very low (11 USD for “Business” Plan, actually it is Shared Server) plus you’ll get $100 Google AdWords Voucher. There is no loss for that month, you can run PHP scripts, Perl Scripts. Actually, within being same system (we are taking about being on Amazon, Rackspace etc.), there can be bizarre errors during moving due to conflicts.

Transfer FTP Files Directly From One Server to Another : Major Methods

First, you need to Zip. We are describing the first set of methods for those who has no command line root access, Like in case of Rackspace Cloud Sites. We have very easy WordPress Plugin named FTP to Zip to zip all the contents of public folder. There are Perl and PHP scripts available to pull from another server, a simple PHP script will be like this :

<?php   
    echo "The Script is Working...<br>";  
    $fck = file_get_contents('http://downloads.wordpress.org/plugin/ftp-to-zip.1.8.zip') or die('Failed to Fetch the File');  
    $fp  = fopen('./ftp-to-zip.1.8.zip', 'w+') or die('Something Went Wrong?');  
    fputs($fp, $fck) or die('Could not write to the file'); 
    fclose($fp);    
    unset($fck);    
    echo "All Done!";
?>

<?php

echo "The Script is Working...<br>";

$fck = file_get_contents('http://downloads.wordpress.org/plugin/ftp-to-zip.1.8.zip') or die('Failed to Fetch the File');

$fp = fopen('./ftp-to-zip.1.8.zip', 'w+') or die('Something Went Wrong?');

fputs($fp, $fck) or die('Could not write to the file');

fclose($fp);

unset($fck);

echo "All Done!";

?>

Note that :

 # The $fck is just a name and the url is for example
$fck = file_get_contents('http://downloads.wordpress.org/plugin/ftp-to-zip.1.8.zip') or die('Failed to Fetch the File');  
# In the same way :
$fp  = fopen('./ftp-to-zip.1.8.zip', 'w+')
# the file name & extension should be mentioned

There is an excellent tool for Rackspace Cloud Sites named Zipit. It is fully free software and you can grab it from Github or Rackspace’s guide pages. It zips and uploads both FTP content and MySQL database to Cloud Files. The Cloud Files container remains Private. You can use Hostgator like web host and change DNS to fetch content if you are not using Rackspace Cloud Sites, in fact we used Hostgator to simplify the migration. It is a fully third party, to the chance of messing up is less. With Clouflare it takes 5 minutes to propagate domain name. Most have many unused domains.

There is no other practical method to Transfer FTP Files Directly From One Server to Another without any error, in case root access is not available. FTP menthols usually fails if both server has no root access. With SFTP and WinSCP it is possible to automate :

In case, both hosts has no root access, still you can use com monad line on your computer to wget* the tar ball. At least you can resume with -c function in case downloading halts. Downloading with GET function (over browser) is risky for bigger files.

Transfer FTP Files Directly From One Server to Another : Major Methods With Command Line

Cream. There are hundreds of methods. The new Server with root access is actually a full computer. So you can run SFTP commands :

$ cd /var/www
$ pwd
/var/www
$ sftp username@RackspaceIP
ftp > cd www.your-site.com/web/content/
ftp > get -r *
# or
ftp > get -r www.your-site.com/web/content

$ cd /var/www

$ pwd

/var/www

$ sftp username@RackspaceIP

ftp > cd www.your-site.com/web/content/

ftp > get -r *

# or

ftp > get -r www.your-site.com/web/content

It has resume function. Another popular method is using rsysc. You need to install rsync on new server; usage is like this :

$ rsync -v -e ssh /www/content.tar.gz username@RackspaceIP:~
# run man rsync to view the usage

1 2	$ rsync -v -e ssh /www/content.tar.gz username@RackspaceIP:~ # run man rsync to view the usage

*Last way is to use our favorite wget command. GNU wget is so powerful, we love it. Simply,

wget http://your-site.com.tar.gz
# if breaks continue
wget -c http://your-site.com.tar.gz

wget http://your-site.com.tar.gz

# if breaks continue

wget -c http://your-site.com.tar.gz

or make the Cloud Files CDN Public and wget it. Obviously, untar it using tar -xzvf command.

Note : New Generation Cloud Servers of Rackspace needs no need to copy in this way. You can backup using create image function.
