Overview

A snapshot is a point-in-time capture of data status in a disk. Before you perform mission-critical operations, you can take snapshots for the data volume or root volume of a VM instance so that you can immediately roll back on failure. For long-term backup, we recommend that you use disaster recovery related services.
