milvus-backup是不是强制备份到MinIO ?

[carrison]

cat backup.yaml
milvus:
address: "localhost:19530"
port: "19530"
storage:
type: "file"
path: "/data/backup"
root@worker01:/data/backup# cat > backup.yaml << 'EOF'
milvus:
address: "localhost"
port: "19530"
storage:
type: "file"
path: "/data/backup"
EOF
root@worker01:/data/backup# milvus-backup create -d "file-backup-$(date +%Y%m%d_%H%M%S)"

backup.yaml
docker start minio 2>/dev/null || docker run -d
-p 9000:9000
-p 9001:9001
--name minio
-v ~/minio/data:/data
-e "MINIO_ROOT_USER=minioadmin"
-e "MINIO_ROOT_PASSWORD=minioadmin"
minio/minio server /data --console-address ":9001"
启动minIO容器后，可以备份milvus了
不过milvus-backup不支持备份数据库A，恢复到数据库B

1. MinIO 不是必须的

milvus-backup 支持多种存储后端：

本地存储配置示例：
minio:
storageType: "minio" # Milvus 数据源
address: localhost
port: 9000

backupStorageType: "local"     # 备份目标：本地磁盘
backupRootPath: "/data/backup/"

2. 支持从数据库 A 恢复到数据库 B

CLI 方式 - 使用 --rename 参数：
milvus-backup restore
--name backup_name
--rename "db_A.collection1:db_B.collection1,db_A.collection2:db_B.collection2"

支持的格式：

• db1.coll1:db2.coll2 - 集合重命名并移动到不同数据库
• db1.:db2. - 通配符，将 db1 所有集合移动到 db2

REST API 方式 - 使用 restorePlan：
{
"backup_name": "backup_A",
"restorePlan": {
"mapping": [{
"source": "database_A",
"target": "database_B",
"colls": [
{"source": "users", "target": "users"}
]
}]
}
}
