Example

import (
	"context"
	"fmt"

	"github.com/milvus-io/milvus/client/v2/milvusclient"
)

ctx, cancel := context.WithCancel(context.Background())
defer cancel()

milvusAddr := "YOUR_CLUSTER_ENDPOINT"

cli, err := milvusclient.New(ctx, &milvusclient.ClientConfig{
	Address: milvusAddr,
})
if err != nil {
	log.Fatal(err)
}

defer cli.Close(ctx)

option := milvusclient.NewDescribeSnapshotOption("backup_20260418", "my_collection")

resp, err := cli.DescribeSnapshot(ctx, option)
if err != nil {
	// handle error
}

fmt.Println(resp.GetName())
fmt.Println(resp.GetCollectionName())
