Snapshots allow you to take a snapshot of an image of a disk in DigitalOcean. Later, you can restore the snapshot if something goes wrong with the disk.
You can also create a snapshot of a running instance.
Snapshots are a great way to protect your data. For example, you can take a snapshot of your data every night so that you can restore it if something goes wrong during the day.
PRO TIP: Please be aware that snapshots in DigitalOcean are not backups. If you delete a droplet, the snapshots associated with that droplet will also be deleted.
You can also use snapshots to experiment with new versions of your software without risking your live data.
Conclusion
Snapshots are a great way to protect your data and experiment with new versions of your software.
