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 Convert to Snapshot will convert the selected backup to a DigitalOcean snapshot. Unlike backups, which are only retained for four weeks, a snapshot is retained indefinitely. When you choose to convert a backup to a snapshot, it will be removed from the list of available backups and added to the list of snapshots.
Once a backup is converted to a Snapshot, snapshot pricing applies.
Converting a backup to a snapshot can be useful if there is a backup that you would like to retain for an extended period of time. It’s also useful if you would like to copy a snapshot to different regions, which is possible with a snapshot, but not with a backup.
