环境
milvus：v2.2.4
go：1.20.2 darwin/amd64
milvus-backup：v0.2.2
代码准备
https://github.com/zilliztech/milvus-backup/releases
如果你的milvus是2.2.9版本及以上，可以直接下载最新的版本：git clone https://github.com/zilliztech/milvus-backup.git
默认使用的配置文件在config目录下，如果不需要手动指定，直接修改改文件即可，主要修改milvus和minio相关配置即可
示例：
# Configures the system log output.
log:
level: info # Only supports debug, info, warn, error, panic, or fatal. Default 'info'.
console: true
file:
rootPath: "logs/backup.log"
http:
simpleResponse: true
# milvus proxy address, compatible to milvus.yaml

authorizationEnabled: false
# tls mode values [0, 1, 2]
# 0 is close, 1 is one-way authentication, 2 is two-way authentication.
tlsMode: 0

# Related configuration of minio, which is responsible for data persistence for Milvus.
minio:
address: minio.openai.svc.t2.test.xdf.cn # Address of MinIO/S3
port: 80 # Port of MinIO/S3
accessKeyID: xxxx # accessKeyID of MinIO/S3
secretAccessKey: xxxx # MinIO/S3 encryption string
useSSL: false # Access to MinIO/S3 with SSL
useIAM: false
cloudProvider: "aws"
iamEndpoint: ""
bucketName: "milvus-t" # 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
backupBucketName: "milvus-t-backup-all" # Bucket name to store backup data. Backup data will store to backupBucketName/backupRootPath
backupRootPath: "files" # Rootpath to store backup data. Backup data will store to backupBucketName/backupRootPath

遇到的问题
我刚开始下载的是最新的源码
- this version of sdk is incompatible with server, please downgrade your sdk or upgrade your server
文章来源：https://www.toymoban.com/news/detail-605233.html
解决：milvus版本过低，与源码所支持的不一致，下载非最新版本的milvus-backup解决。文章来源地址https://www.toymoban.com/news/detail-605233.html
