On the Snapshot Status, the process continues till Completed appears. 

Note: You can always keep the same Snapshot up to date with clicking Update link in a short time. 

Restore from Snapshot and Change disk size

You can choose a Snapshot created earlier from the list or you can choose one of the automated snapshot which is created by the system automatically every hour. Enter the new disk size and choose one of the Snapshot which is created by yourself or the latest Snapshot which is created by the system automatically atmost 1 hour ago.

Note: Do not forget, to restore your server, your server must be launched at least 1 hour ago or there should be an Automated Snapshot which is created by the system.

While processing a little time, server will prepare it's hardware so it will be unreachable for a short time and then rebooted.
