The OVH Cloud Snapshot API allows users to easily create, manage, and restore snapshots of their virtual server instances. With this API, users can schedule and automate the process of taking snapshots, which are essentially a point-in-time copy of the server's data and configuration. These snapshots can be used to back up important files and settings, as well as to quickly restore the server to a previous state in case of data loss or system failure. The API provides a convenient way for users to protect their data and ensure the availability of their server instances.
