Generally, its good to have a backup of online website. Thankfully, DigitalOcean has the feature to enable the weekly droplet backups at a nominal cost. If you’re running a WordPress Blog, then having a remote backup is also a must along with this weekly backup, by the way — this is for free.
Apart from the Backup, the DigitalOcean also supports taking a snapshot of the server in real-time. This snapshot can be used for recreating or spinning another droplet using same settings and configurations.
In this article, learn how to enable the weekly droplet backups option which an in-built feature in DigitalOcean cloud console. And also taking the real-time snapshot image of the entire server.
Without further ado, let’s get started with DigitalOcean Droplet Backups & Snapshot —
Enabling Weekly Droplet Backups in Console
Liked I mentioned, the backup is a built-in feature available in every droplet (server) in DigitalOcean. All we need is to enable the weekly droplet option to get started.
Follow the below steps to enable the Weekly Droplet backups in DigitalOcean:
- Login to DigitalOcean cloud console
- Select the Project and then Droplet that you need to enable backups
- Within Droplet, you’ll be having an option for Backups (in the left sidebar), click and navigate to the page
- Hit on [Enable Backups] command button
- That’s it! Weekly backups are now enabled
Please note that Droplet backups incur the additional cost which I think is very nominal. The charges are 20% of your actual droplet cost. Say suppose you spin a droplet server of $10, then the monthly backup charges are 20% of $10 which is $2.
DigitalOcean retains around 4 to 5 droplet backup at an interval of 1 week. If the new backup is added today, then oldest back is automatically purged.
Using these backups, you can perform 3 tasks:
- Convert into Snapshot
- Create a new Droplet
- Restore the Droplet
If you convert the Droplet Backup into Snapshot, this will further enable to perform snapshot actions.
Power Off and Take a Snapshot of Cloud Server
While the Backups feature is automatic and not real-time, Snapshot is another option of backing up the server droplet. The snapshot is a manual process but in real-time.
The snapshot is really helpful when you want to immediately spin a duplicate droplet in some other region or change the ownership. Also, if you’re making a major upgrade on your server or website, then it’s a good idea to have snapshot just in case if things go out of the way.
But when it comes to taking a snapshot image of your droplet, it’s recommended to poweroff cloud server to maintain the consistency in data. Hence, I personally do not recommend taking a snapshot on a live site. However, this shouldn’t be a problem of test or staging site.
Also, we can power off the droplet from DigitalOcean console, however, it’s not recommended. Instead, we should power off from the SSH login on Cloud Server.
Follow the below steps to power off and take a snapshot of DigitalOcean droplet:
- Login to SSH client of your cloud server
- Run the poweroff command to turn off the server
- Next, log in to DigitalOcean cloud console
- Navigate to Projects and then select the Droplet
- Access the Snapshot tab available in the left sidebar within Droplet area
- Make sure that Droplet is PowerOff and hit on [Take live snapshot] command
- Wait* for the process to complete — a progress bar will be displayed
- Your snapshot will be ready once the process is completed
[*Processing snapshot takes around 1 min per GB]
Once the droplet processing is completed, do not forget to Power ON the droplet by toggling the power button available in the droplet console. You can also visit the Power tab available in Droplet to turn on the droplet.
Just like backups, the snapshot also incurs charges however they are charged on the basis of GB storage. It charges are $0.05 per GB per month of actual files and data storage.
There is no limitation as in how long you want to retain the snapshot image in your cloud console. You need to manually delete the snapshot image to stop the overhead charges.
Like mentioned above, once the snapshot is created you can perform the following actions:
- Change Ownership
- Create a New Droplet
- Restore the Snapshot
- Add the Snapshot to new Region
- Destroy the Snapshot
Basically, we can use two types of migration technique in this —
- Changing the Ownership
- Migrating the Droplet Snapshot to a different region
But, you may not be able to migrate the snapshot out of DigitalOcean. However, you can use the scp command for migrating entire folders and files from one server to another.
