DigitalOcean Backups and Snapshots Explained

Posted Aug 31, 2012 278.8k views DigitalOcean Backups

About Backups

Backups are an important part of any secure system. DigitalOcean offers two main backup types, snapshots and backups, that can be used to not only save and restore important data in case of a server issues, but also to scale servers or duplicate helpful configurations.

Please note that automated backups running on a server with an active database can result in an incomplete backup of your database. If you are relying on the automated backups to back up a database server, we highly suggest that you use a tool to periodically export your database, such as mysqldump or pg_dump. The exported file can be safely backed up and can be used to perform a database restore.

Backups vs. Snapshots

DigitalOcean users have the option of backup and snapshot features. The main difference between the two is that snapshots can be generated manually, while backups are run automatically weekly.

Once the files are saved, both the snapshots and backups are stored on hardware separate from the droplet resources.

Snapshots and Backups Pricing

The pricing for backups is 20% of the cost of the virtual server. So if you want to enable backups for a $5/mo virtual server, the cost for backups will be $1/mo.

The 20% cost for backups assumes at least four successful backups per month. If for any reason one of those backups should fail, you will not be charged for that backup. For example, if 3 out of 4 backups are successful, your backups will cost 15% the cost of your server that month. You will not be charged beyond the fourth backup in a single month.

Starting in October of 2016, the cost for snapshots is $0.05 per gigabyte per month, based on the amount of utilized space within the filesystem. Snapshots that are destroyed before the month is over will be charged hourly, just like Droplets.

Snapshot Uses

Scaling:Snapshots can provide an easy way to scale out a system: you can take a snapshot of a current server and spin up a new droplet from the snapshot. As soon as the process completes, you will have two identical servers to bolster your setup.

Occasional Usage: Snapshots can also provide a way to use droplets for a limited time without having to pay for the Droplet itself when the server is not in use. Should you only need to use a server for a certain time every so often, you can take a snapshot of your current configuration, delete the Droplet, and spin the system back up as soon as you need it once again—the image will remain in your account, and you will only be charged for the cost of the snapshot.

Backups: While automated backups make sure that is always a version of your system available in case of trouble, snapshots have the added benefit of being possible at any time. A snapshot could be taken prior to making any drastic changes to a server configuration, so that, should the changes be unsuccessful, you will have a version to revert back to.
