Backup your WordPress site:
BackupBuddy makes it easy to save either just your website database or a zip file of your entire WordPress site. Other free WordPress plugins will backup just your database but if your computer dies and you’ve lost original images and other files you will be facing a lot of work to restore your site. BackupBuddy saves it all. Hopefully you will never need it but if you do BackupBuddy will be money well spent!
You can schedule backups to happen automatically on a regular basis. You can also do a manual backup just before updating your WordPress installation and plugins. That way if your site crashes you can relax knowing you have a complete current backup.
You can even set BackupBuddy to save to a remote off-site location such as a Dropbox folder, Amazon S3, Rackspace Cloud, an FTP/FTPS account, or to your email.
Migrate a WordPress site to another domain or server:
WordPress developers who build a custom site for a client on a temporary domain or locally (like a sandbox or playground site) and then want to migrate the entire site with content, styles, widgets and all on a live client domain will find that Backup Buddy does it all for them. You upload the importbuddy.php script and your backup file, and it restores WordPress: your themes, widgets, plugins, and everything else. No need to install WordPress first!
After purchasing save the zip file to your computer. Then go to plugins and click add new, upload the file and activate the plugin.
To work, BackupBuddy will need a license key. Click on “Licenses” beside the key icon in your list of plugins. Enter you PluginBuddy / iThemes Member account information (it was emailed to you when you purchased the plugin). And you will be able to click and generate a unique license key for each web site.
BackupBuddy is a straightforward easy-to-use plugin that is very reasonably priced. I highly recommend it! You can buy backupbuddy through this affiliate link – WordPress BackupBuddy. The Developer license is a great deal giving you a suite of great plugins for one price.
