Currently, there is no command to restore data with snapshots. You need to manually copy the snapshot file to the corresponding folder, or you can make it by using a shell script. The logic implements as follows:

1. After the snapshot is created, the `checkpoints` directory is generated in the installation directory of the leader Meta server and all Storage server, and saves the created snapshot. Taking this topic as an example, when there are two graph spaces, the snapshots created are saved in `/usr/local/nebula/data/meta/nebula/0/checkpoints`, `/usr/local/nebula/data/storage/ nebula/3/checkpoints` and `/usr/local/nebula/data/storage/nebula/4/checkpoints`.

The data and wal directories of all Meta nodes should be overwritten at the same time. Otherwise, the new leader Meta node will use the latest Meta data after a cluster is restarted.
