收到 DigitalOcean 的信件通知,snapshot 會開始收費:
Starting October 1, 2016, we will begin charging for snapshot storage at $0.05 per gigabyte per month. This will first be reflected in the invoice posted to your account on November 1, 2016. Like other features, snapshot storage uses hourly pricing, and size is calculated from a compressed version of the snapshot—not the total disk space allocated to the Droplet.
