WordPress Backup to Dropbox is a WordPress plugin by michael.dewildt that automatically creates a backup your WordPress blog and uploads it to Dropbox.
You can choose a day, time and how often you wish yor backup to be performed and kick back and wait for a zipped archive of your websites files and its database to be dropped in your Dropbox!
The Backup to Dropbox settings page is located under the WordPress settings menu. Within this page you can set the following:
‘Locally store backup in this folder’ – This is where you want the backup to be stored on your WordPress server. This can be a temporary storage location with the ‘Keep local backup’ setting below.
‘Keep local backup’ – If this is set to true then a copy of the backup uploaded to Dropbox will remain on your WordPress server in the above folder.
‘Store backup in this folder within Dropbox’ – This is where the backup is stored within your Dropbox.
‘Day and Time’ – Select the day and time that you wish your backup to be performed. Remember that someone will need to access a page on your site in order to kick off the backup, and that the user is not affected by this process at all.
‘Frequency’ – Select how often you would like your backup to be performed.
‘Backups to keep’ – This is the number of backups you wish to keep on your WordPress server and within your Dropbox. When the setting value is reached the plugin will replace the oldest backup with the newly created one.
The plugin uses OAuth so your Dropbox account details are not stored for the plugin to gain access.
