This script backups both the database and files of a WordPress blog into a remote FTP server (while keeping a local copy). It’s an update of my WordPress Backup to FTP script. The main changes are auto-detecting database settings and better support for caching plugins (specifically WP-Cache). The new version makes it easier to backup multiple WordPress blogs to the same FTP server.
Usage is pretty simple after a short initial configuration. First, save the the script and make it executable:
chmod +x wp-backup |
(assuming you saved it under the name wp-backup). After saving it edit the file with your favorite editor and set the 5 configuration variable to whatever is appropriate for you. BACKUP_DIR is the folder to save the local backups to. FTP_HOST, FTP_USER, FTP_PASS control the FTP host, username and password, respectively, for the remote backup server. FTP_BACKUP_DIR sets the folder on the FTP server to save the remote backup to.
Now that the initial configuration is done, all you need to do is execute the script and give the path to the blog as an argument. For example:
./wp-backup /home/someuser/myblog |
And that it, the script will backup your files (excluding cache) and database to both a local and remote locations. This allows using the same script to backup multiple WordPress blogs, unlike the previous script which had to be modified for each blog.
And now the script itself:

Awesome script, i hosted my website on a free webhost, when i tried to make a back up using their backup tool, i got an error message, and after that i was looking for another option to back up my site, and this script is most useful. thank you for such a wonderful script

I just took it and copied the entire folder. Is that bad?
You should also have a dump of your db along side it.
