The command etcdctl snapshot restore ${path-to-snapshot-db} is used to restore an etcd database from a snapshot file.

• etcdctl is the command line interface (CLI) tool for interacting with etcd, a distributed key-value store used for storing and managing the cluster's configuration data.
• snapshot is a feature in etcd that enables taking a backup of the entire database at a given point in time.
• restore is the subcommand in etcdctl used to restore a snapshot file to the etcd instance.
• ${path-to-snapshot-db} is the placeholder for the path to the snapshot database file. You need to provide the actual path to the snapshot you want to restore, including the filename.

To use this command, you should have etcdctl installed and configured to connect to the etcd cluster. The etcd cluster must also be stopped before restoring the snapshot to prevent any conflicts.

Once executed, etcdctl snapshot restore will read the specified snapshot file, extract the database contained within it, and restore it to the etcd cluster. After the restore process is completed, you can start the etcd cluster again, and it will use the restored data.
