快照（Snapshot）可以说是备份以及环境配置的利器，之前DigitalOcean一直是免费向客户提供这一服务，但是近期DO官方决定将于2016年11月1日起对这一服务开始收费，收费的标准为0.05美元/G/月，计费采用小时制计费。另外，官方会在10月1日时另外发布提醒，如果你有不需要的Snapshot，尽快处理掉，否则可能会给你带来不必要的费用支出
官方邮件如下，
Snapshots billing update
We are in the process of making updates to our snapshot policy and wanted to let you know what you will be seeing.
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.
Also, you can now take Droplet snapshots without having to power off the Droplet. You can see this in action by taking a snapshot of a Droplet while it’s still running.
Over the coming weeks, we will update the Snapshots page to show the costs associated with your snapshot storage more easily and we’ll also send another reminder before charges begin on October 1, 2016. Be sure to see your usage on the Snapshots page and delete unused snapshots to avoid any unexpected charges.
In the meantime, if you have any questions or feedback about the upcoming changes, you can always open a ticket and our Support team will be glad to help.opening a support ticket.
Thanks,
Team DigitalOcean
