使用restic备份数据至阿里云oss

初始化repo: restic -o s3.bucket-lookup=dns -o s3.region=oss-cn-beijing -r s3:https://xxx(bucket_name).oss-cn-beijing.aliyuncs.com init

   -o s3.bucket-lookup=dns: 通过Virtual path host连接(阿里云限制)

   -o s3.region=oss-cn-beijing: bucket所在区域

   -r s3:https://xxx(bucket_name).oss-cn-beijing.aliyuncs.com: Bucket域名

备份: restic -r s3:https://xxx(bucket_name).oss-cn-beijing.aliyuncs.com --verbose backup c:\temp(需要备份的目录或文件)

　--verbose: 显示详细信息

需要修改代码, Go语言不太熟悉, 改的合不合理不太清楚.

文件: internal/backend/s3/config.go

修改前(57~62行):

		if url.Path == "" {
			return nil, errors.New("s3: bucket name not found")
		}

		path := strings.SplitN(url.Path[1:], "/", 2)
		return createConfig(url.Host, path, url.Scheme == "http")

修改后:

		var path []string
		if url.Path == "" {
			temps := strings.SplitN(url.Host, ".", 2)
			path = append(path, temps[0])
			url.Host = temps[1]
		} else {
			path = strings.SplitN(url.Path[1:], "/", 2)
		}

		return createConfig(url.Host, path, url.Scheme == "http")

　　

有用的环境变量:

RESTIC_PASSWORD_FILE: 可以将密码保存至文件中, 在进行备份时不需要输入密码. 设置文件路径.

RESTIC_REPOSITORY: 指定默认存储库位置, 后续处理中可不指定-r参数
