上一篇文章：Typecho 博客脚本备份与恢复 中有提到怎么用脚本定时备份网站数据库。今天来分享下如何使用 Rclone 将备份的数据，自动同步到 Google 云盘或者阿里云 OSS 等 S3 存储上。
一、安装 Rclone#
登录到服务器终端，执行下方命令：
curl https://rclone.org/install.sh | sudo bash
如果之前没有安装过curl，请执行下方命令完成安装：
yum -y install curl
二、配置 Rclone#
安装成功后，输入：
rclone config
弹出下方操作命令，按提示操作即可：
2021/05/09 12:48:01 NOTICE: Config file "/root/.config/rclone/rclone.conf" not found - using defaults
No remotes found - make a new one
n) New remote
s) Set configuration password
q) Quit config
输入n新建，name自定义后，弹出要连接的存储：

endpoint> 8
Canned ACL used when creating buckets and storing or copying objects.
This ACL is used for creating objects and if bucket_acl isn't set, for creating buckets too.
For more info visit https://docs.aws.amazon.com/AmazonS3/latest/dev/acl-overview.html#canned-acl
Note that this ACL is applied when server-side copying objects as S3
doesn't copy the ACL from the source but rather writes a fresh one.
Enter a string value. Press Enter for the default ("").
Choose a number from below, or type in your own value
1 / Owner gets FULL_CONTROL. No one else has access rights (default).
\ "private"
2 / Owner gets FULL_CONTROL. The AllUsers group gets READ access.
\ "public-read"
/ Owner gets FULL_CONTROL. The AllUsers group gets READ and WRITE access.
3 | Granting this on a bucket is generally not recommended.
\ "public-read-write"
4 / Owner gets FULL_CONTROL. The AuthenticatedUsers group gets READ access.
\ "authenticated-read"
/ Object owner gets FULL_CONTROL. Bucket owner gets READ access.
5 | If you specify this canned ACL when creating a bucket, Amazon S3 ignores it.
\ "bucket-owner-read"
/ Both the object owner and the bucket owner get FULL_CONTROL over the object.
6 | If you specify this canned ACL when creating a bucket, Amazon S3 ignores it.
\ "bucket-owner-full-control"
acl> 3

Enter a string value. Press Enter for the default ("").

可以看到需要输入阿里云 OSS 的 ID 和密钥，可以先回车跳过，在阿里云配置好后再来编辑这部分；然后按照提示选择阿里云 OSS 的节点位置和读写权限，可参考上述选择（以香港节点、公共读写权限为例），若是其他节点，选择对应序号即可。
三、阿里云 API 配置#
登录阿里云网页，点击右上角头像，进入访问控制，创建一个新用户，点选编程访问，并添加AliyunOSSFullAccess权限。
之后就可以获得阿里云 OSS 服务的 ID 和密钥了。
四、继续配置 Rclone#
重新在终端输入rclone config命令，按照下方操作进入编辑模式，补充阿里云 OSS 的 ID 和密钥。

到这里 Rclone 连接阿里云 OSS 的配置就全部完成了，想要连接 Google Drive 等其他存储，也是类似的道理。
五、脚本修改#
在备份脚本的后面加上：
rclone copy /path/backup Alibaba:BucketName
其中/path/backup代表数据备份的目录，Alibaba:BucketName中的Alibaba是rclone操作过程中，新建的remote名称，后面的BucketName则是你阿里云 OSS 的存储桶名称。
如果想要定时自动同步数据到阿里云 OSS 的话，可以在终端键入crontab -e，然后输入：
0 18 * * 5 /bin/bash /root/jiaoben/backup.sh
其中：0 18 * * 5代表每隔 7 天的下午 6 点钟执行一次后面的命令；root bash代表以 root 身份执行 bash 命令；/path/backup.sh代表备份脚本存放的位置；/path/wwwroot/domain.com代表网站的根目录。
