no binlog to import is usually caused by a bucket misconfiguration. Milvus can only read files from its own bucket — it cannot read across buckets.

Please make sure minio.bucketName in backup.yaml matches the target Milvus bucket. Run ./milvus-backup check to verify.

no binlog to import 通常是 bucket 配置不匹配导致的。Milvus 只能读取自己 bucket 下的文件，没有跨桶读取的能力。

请确认 backup.yaml 中的 minio.bucketName 与目标 Milvus 的 bucket 一致，可以通过 ./milvus-backup check 验证。

用的存储类型： local ，这种呢？

./milvus-backup check 执行结果：
Milvus version: 2.6.8
Storage:
milvus-storage-type: local
milvus-bucket: data
milvus-rootpath: /data/sunshuqi/nd-install/volumes/milvus/data
backup-storage-type: local
backup-bucket: data
backup-rootpath: /data/sunshuqi/nd-install/backup

Success!

[yiziqing]

上面是 local 模式下 no binlog to import，该怎么解决呢？

[huanghaoyuanhhy]

Local storage does not support restore yet. See #985 for the ongoing work. Welcome to contribute a PR if you're interested.

local 存储模式目前还不支持 restore，相关工作见 #985，欢迎贡献 PR。
