At Digital Ocean you pay for the amount of storage your snapshot takes. This is priced at a simple $0.06 per gigabyte per month. This is different to Digital Ocean backups which are priced at 20% of the cost of the droplet no matter how much disk space you use. Backups are limited to once a week and only the last 4 weeks are retailed, where you can have as many snapshots as you wish.
