Kopia 加密备份（在 Kopia 中称为 snapshots ）保存到各种存储位置，在 Kopia 中，存储位置称为 repository。

  • Kopia 原生支持 Google Drive，并通过 Kopia 的 Rclone 选项（见下文）。
  • Kopia 对 Google Drive 的原生支持目前处于实验阶段。
  • 原生 Google Drive 支持的运作方式与 Kopia 通过 Rclone 对 Google Drive 的支持不同。

本文介绍如何通过 Rclone 实现对 Google Drive 的支持。

Rclone

Rclone 是一个（免费且开源）第三方程序，Kopia 的 Docker 镜像中包含了 Rclone，但我们还是下载一份用来生成配置文件。

cd && mkdir rclone
curl -O https://downloads.rclone.org/rclone-current-linux-amd64.zip
unzip rclone-current-linux-amd64.zip
cd rclone-*-linux-amd64
./rclone config

下面是如何创建一个名为“remote”的示例。第一次运行：

No remotes found, make a new one?
n) New remote
r) Rename remote
c) Copy remote
s) Set configuration password
q) Quit config
n/r/c/s/q> n
name> remote
Type of storage to configure.
Choose a number from below, or type in your own value
[snip]
XX / Google Drive
   \ "drive"
[snip]
Storage> drive
Google Application Client Id - leave blank normally.
client_id>
Google Application Client Secret - leave blank normally.
client_secret>
Scope that rclone should use when requesting access from drive.
Choose a number from below, or type in your own value
 1 / Full access all files, excluding Application Data Folder.
   \ "drive"
 2 / Read-only access to file metadata and file contents.
   \ "drive.readonly"
   / Access to files created by rclone only.
 3 | These are visible in the drive website.
   | File authorization is revoked when the user deauthorizes the app.
   \ "drive.file"
   / Allows read and write access to the Application Data folder.
 4 | This is not visible in the drive website.
   \ "drive.appfolder"
   / Allows read-only access to file metadata but
 5 | does not allow any access to read or download file content.
   \ "drive.metadata.readonly"
scope> 1
Service Account Credentials JSON file path - needed only if you want use SA instead of interactive login.
service_account_file>
Remote config
Use web browser to automatically authenticate rclone with remote?
 * Say Y if the machine running rclone has a web browser you can use
 * Say N if running rclone on a (remote) machine without web browser access
If not sure try Y. If Y failed, try N.
y) Yes
n) No
y/n> y
If your browser doesn't open automatically go to the following link: http://127.0.0.1:53682/auth
Log in and authorize rclone for access
Waiting for code...
Got code
Configure this as a Shared Drive (Team Drive)?
y) Yes
n) No
y/n> n
--------------------
[remote]
client_id = 
client_secret = 
scope = drive
root_folder_id = 
service_account_file =
token = {"access_token":"XXX","token_type":"Bearer","refresh_token":"XXX","expiry":"2014-03-16T13:57:58.955387075Z"}
--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y

初始设置涉及从 Google 驱动器获取令牌，我们需要在浏览器中执行此操作，这里我们可以通过 caddy 反代来打开 http://127.0.0.1:53682/auth。

进入目录 /etc/caddy/sites，创建并编辑 kopia.amaranthinking.eu.org.conf，

kopia.amaranthinking.eu.org {
  reverse_proxy 127.0.0.1:53682
}

重启 caddy,

systemctl restart caddy

访问 kopia.amaranthinking.eu.org/auth 即可，生成完毕后记得删除临时的反代配置。

注意：生成的 rclone 配置文件位于 /root/.config/rclone/rclone.conf。

Kopia

接下来，将配置文件移动动 kopia 文件夹，

mv /root/.config/rclone/rclone.config /root/data/docker/kopia/rclone.conf

编辑 docker-compose.yml 文件，文件尾添加：

      # Mount rclone config file
      - ./rclone.conf:/app/rclone/rclone.conf

重启，

cd /root/data/docker/kopia/
docker-compose down
docker-compose up -d

设置 Rclone 后，Kopia 会自动管理和运行 Rclone，我们无需进行初始设置之外的太多操作。
