最近在幫自己的網站從 Vultr 搬到自己家裡的主機，因為家裡的主機是拿老桌機當 Server 用，怕隨時硬碟會炸掉XD，於是就有了這個備份需求，直接丟到學校提供的Google Drive 教育板，就不用太擔心了。
目前這個需求已經有人開發了工具，可以直接結合 Proxmox VE 內部的備份工具，可以在 Backup Log 中看到 Rclone 的相關 Log，搭配 Proxmoe VE 內建 CRON 自動備份到各種網路空間，非常方便：
安裝 Rclone
在 Proxmox VE 中以 root 身份登入，直接使用指令安裝 rclone
# apt update # apt install rclone -y
亦或到 Rclone 的官網下載安裝：
初始化 Rclone
請務必仔細跟著設定，或是你自己去研究 rclone 的 config
# rclone config
2021/10/08 02:03:49 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
n/s/q> n
name> gd-backup_crypt # 務必使用這個名字，或是之後改腳本
Type of storage to configure.
Enter a string value. Press Enter for the default ("").
Choose a number from below, or type in your own value
~~
15 / Google Drive
\ "drive"
~~
Storage> 15
Google Application Client Id
Setting your own is recommended.
See https://rclone.org/drive/#making-your-own-client-id for how to create your own.
If you leave this blank, it will use an internal key which is low performance.
Enter a string value. Press Enter for the default ("").
client_id> 123456789-xxxxxxxxxxxxxx.apps.googleusercontent.com
OAuth Client Secret
Leave blank normally.
Enter a string value. Press Enter for the default ("").
client_secret> xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Scope that rclone should use when requesting access from drive.
Enter a string value. Press Enter for the default ("").
Choose a number from below, or type in your own value
1 / Full access all files, excluding Application Data Folder.
\ "drive"
~~
scope> 1
ID of the root folder
Leave blank normally.
Fill in to access "Computers" folders (see docs), or for rclone to use
a non root folder as its starting point.
Enter a string value. Press Enter for the default ("").
root_folder_id> xxxx_123456789
# 在 Google Drive 建一個資料夾，網址最後一串就是 root_folder_id
# https://drive.google.com/drive/u/1/folders/xxxx_123456789
Service Account Credentials JSON file path
Leave blank normally.
Needed only if you want use SA instead of interactive login.
Leading `~` will be expanded in the file name as will environment variables such as `${RCLONE_CONFIG_DIR}`.
Enter a string value. Press Enter for the default ("").
service_account_file> [Enter]
Edit advanced config?
y) Yes
n) No (default)
y/n> [Enter]
Use auto config?
* Say Y if not sure
* Say N if you are working on a remote or headless machine
y) Yes (default)
n) No
y/n> n
Verification code
Go to this URL, authenticate then paste the code here.
https://accounts.google.com/o/oauth2/auth?xxxxxxxxxx
# 複製上面網址到瀏覽器登入帳號，取得驗證碼填入下方
Enter a string value. Press Enter for the default ("").
config_verification_code> 123454321
2021/10/08 02:16:42 NOTICE: Make sure your Redirect URL is set to "urn:ietf:wg:oauth:2.0:oob" in your custom config.
Configure this as a Shared Drive (Team Drive)?
y) Yes
n) No (default)
y/n> [Enter]

安裝 proxmox-vzbackup-rclone
下載
以 root 身分執行，這是我修改過的版本：
# apt-get install git # cd /root # git clone https://github.com/fuyuanli/proxmox-vzbackup-rclone.git # git checkout pve7 # chmod +x /root/proxmox-vzbackup-rclone/vzbackup-rclone.sh
修改 vzbackup-rclone.sh
修改第 5 行至你的備份儲存路徑
1 #!/bin/bash
2 # ./vzbackup-rclone.sh rehydrate YYYY/MM/DD file_name_encrypted.bin
3
4 ############ /START CONFIG
5 dumpdir="/data/pve/dump" # Set this to where your vzdump files are stored
備份保留的份數會依據你在 Proxmox VE 的 Backup 選項那邊來刪除，這個腳本只負責上傳檔案到雲端空間
Proxmox VE 7 修正
參考 Issue#7 中提到的方法修正，否則會上傳失敗，我 Fork 後修改的版本已經修正了：
修改第 18 行 tarfile=${TARFILE} 改成 tarfile=${TARGET}
15 if [ ! -z "${3}" ];then
16 CMDARCHIVE=$(echo "/${3}" | sed -e 's/\(.bin\)*$//g')
17 fi
18 tarfile=${TARGET}
19 exten=${tarfile#*.}
20 filename=${tarfile%.*.*}
設定 vzdump.conf
編輯 /etc/vzdump.conf 第 14 行後加入
script:/root/proxmox-vzbackup-rclone/vzbackup-rclone.sh
後存檔
1 # vzdump default settings
2
3 #tmpdir: DIR
4 #dumpdir: DIR
5 #storage: STORAGE_ID
6 #mode: snapshot|suspend|stop
7 #bwlimit: KBPS
8 #ionice: PRI
9 #lockwait: MINUTES
10 #stopwait: MINUTES
11 #stdexcludes: BOOLEAN
12 #mailto: ADDRESSLIST
13 #prune-backups: keep-INTERVAL=N[,...]
14 #script: FILENAME
15 script:/root/proxmox-vzbackup-rclone/vzbackup-rclone.sh
16 #exclude-path: PATHLIST
17 #pigz: N
設定完畢後就可以在 Proxmox VE 的界面備份了，每次備份都會觸發 vzbackup-rclone.sh ，再透過 rclone 上傳，執行 log 如下：

TASK OK
跑完的檔案會在這兩個位置
GoogleDrive/Year/Month/vzdump：VM/LXC 備份
GoogleDrive/Year/Month/pveconfig：/etc/pve/ 備份
檔案還原
使用指令
~/proxmox-vzbackup-rclone/vzbackup-rclone.sh rehydrate
會把上面的備份都下載下來，建議未來有需要時再手動下載就好，我覺得沒有很好用
