``` ```
To create snapshot file with consul version, datacenter, node name and leader/follower info, This is useful for situations where a cluster is in a degraded state and no
run leader is available. To target a specific server for a snapshot, you can run
the `consul snapshot save` command on that specific server.
To create snapshot file with consul version and datacenter run
```shell-session ```shell-session
$ consul snapshot save -append-filename node,status,version,dc backup.snap $ consul snapshot save -append-filename version,dc backup.snap
#... #...
``` ```
File name created will be like backup-%CONSUL_VERSION%-%DC_NAME%-%NODE_NAME%-%STATUS.snap File name created will be like backup-%CONSUL_VERSION%-%DC_NAME%.snap
example - backup-1.17.0-dc1-local-machine-leader.tgz example - backup-1.17.0-dc1-local-machine-leader.tgz
