请问，多台集群备份数据的时候能备份在某一台机器上面吗？

最近想做一个es的集群备份，使用es的__snapshot属性来弄，但是好像多机的时候会报错，报错信息如下：
{
"error": {
"root_cause": [
{
"type": "repository_verification_exception",
"reason": "[my_backup] [E31tFQYgSvqogu-jxMf8Uw, 'RemoteTransportException[[es4][10.200.2.95:9300][internal:admin/repository/verify]]; nested: RepositoryVerificationException[[my_backup] a file written by master to the store [/opt/index_data_backup/my_backup] cannot be accessed on the node [{es4}{E31tFQYgSvqogu-jxMf8Uw}{10.200.2.95}{10.200.2.95:9300}].

}

}

此外，多台集群来备份的话，copy出去以后在镜像导回去也麻烦，还有这个es的镜像能换到其他的es集群里面recovery吗？
