Expected Behavior

No response

Steps To Reproduce

./milvus-backup create -n my_backup

Environment

milvis v2.4.0-rc.1

Anything else?

backup.yaml:

minio:

cloudProvider: "minio" # deprecated use storageType instead

storageType: "minio" # support storage type: local, minio, s3, aws, gcp, ali(aliyun), azure, tc(tencent)

address: localhost # Address of MinIO/S3
port: 9000 # Port of MinIO/S3
accessKeyID: minioadmin # accessKeyID of MinIO/S3
secretAccessKey: minioadmin # MinIO/S3 encryption string
useSSL: false # Access to MinIO/S3 with SSL
useIAM: false
iamEndpoint: ""

bucketName: "a-bucket" # Milvus Bucket name in MinIO/S3, make it the same as your milvus instance
rootPath: "files" # Milvus storage root path in MinIO/S3, make it the same as your milvus instance

Check backetName, rootPath and milvus for consistency
