[haoshuwei]

velero restore get 能看到clusterbk-20200107024432吗

[DeepLJH0001]

@haoshuwei 可以的，显示的状态是失败。

[root@localhost harbor]# velero restore get

[haoshuwei]

velero restore logs clusterbk-20200107023607 |grep error

看下错误日志输出是什么

[haoshuwei]

可能是你的集群在restore的时候有资源冲突，比如port被占用等情况； 一般建议对应用单独备份和恢复，集群备份会涉及到全局范围的一些资源， 容易冲突

能否多一点错误的日志信息，方便进行排查

@DeepLJH0001 可以看看backupstroagelocation的状态是否正常
