Navigate to the Droplet in the DigitalOcean Control Panel, and then click the Backups link. If at least one backup has been taken for your Droplet, it will be listed in the Droplet backups section with a drop-down menu.
Choosing Create Droplet from a backup allows you to create a new Droplet with the disk contents that were saved in the selected backup. This is useful for creating new Droplets with the same data and configuration as the Droplet being backed up. Alternatively, this can be used if you need to view or restore a small number of files to the original Droplet.
Once the new Droplet is created from the backup, you will be able to copy files to the original Droplet using SCP or rsync. See How To Copy Files With Rsync Over SSH for more information on copying files between servers with rsync.
Selecting Restore Droplet from a backup will replace the current Droplet with the backup image. Clicking this option will bring up a window to confirm the action.
Restoring from a backup will take your Droplet offline during the restoration process and bring it back online matching the point in time that the backup was taken. This is useful if you want to completely revert a Droplet to an older point in time, but you will lose any changes on the Droplet that happened after the backup was taken.
