我用基于官方标准docker-compose部署的nebulagraph集群，在参考
NebulaGraph使用docker-compose部署方式如何备份还原 - 文章 / NebulaGraph - NebulaGraph 技术社区 (nebula-graph.com.cn)
这篇文章后，实现了了br工具的备份功能，
但是，在用br进行恢复操作时，看日志显示 ，br恢复时，会将meta/storage/graph服务停止掉，导致恢复失败，此时再看 meta/storage/graph 对应的容器时，都已经停止了，不知是什么原因，
出错的日志如下：

Usage:
br restore full [flags]
Flags:
-h, --help help for full
Global Flags:
–concurrency int Max concurrency for download data (default 5)
–debug Output log in debug level or not
–log string Specify br detail log path (default “br.log”)
–meta string Specify meta server
–name string Specify backup name
–s3.access_key string S3 Option: set access key id
–s3.endpoint string S3 Option: set the S3 endpoint URL, please specify the http or https scheme explicitly
–s3.region string S3 Option: set region or location to upload or download backup
–s3.secret_key string S3 Option: set secret key for access id
–storage string backup target url, format: ://.
: a string indicating which backend type. optional: local, s3.
now only s3-compatible is supported.
example:
for local - “local:///the/local/path/to/backup”
for s3 - “s3://example/url/to/the/backup”
