Ưu điểm của việc sử dụng dịch vụ lưu trữ đám mây đó là tốc độ cao (do có server được đặt trên khắp thế giới), an toàn dữ liệu (không lo ngại các vấn đề phần cứng, network) và nhất là hầu hết đều Free. Mình đặc biệt thích những thứ Free!

Rclone hỗ trợ rất nhiều dịch vụ Cloud thông dụng như:

• Google Drive
• Amazon S3
• Openstack Swift / Rackspace cloud files / Memset Memstore
• Dropbox
• Google Cloud Storage
• Amazon Drive
• Microsoft OneDrive
• Hubic
• Backblaze B2
• Yandex Disk
• SFTP
• The local filesystem

Giờ thay vì backup đưa lên VPS khác để lưu trữ, mình chuyển sang sử dụng Google Drive, dung lượng miễn phí 15GB, mua thêm cũng khá rẻ, chỉ 45k/tháng là được 100GB rồi. Bạn nào có tài khoản Google Apps miễn phí nữa thì càng tuyệt vời.

1. Cài đặt Rclone

Cài đặt với hệ điều hành Linux 64bit

cd /root/
wget https://downloads.rclone.org/rclone-current-linux-amd64.zip
unzip rclone-current-linux-amd64.zip
\cp rclone-v*-linux-amd64/rclone /usr/sbin/
rm -rf rclone-*

2. Tạo kết nối với Goolge Drive

Quá trình cài đặt hoàn tất thì chạy lệnh

rclone config

Bạn sẽ nhận được thông báo: No remotes found - make a new one, nhập n rồi nhấn Enter để tạo kết nối mới.

Ở dòng name bạn nhập remote để đặt tên cho kết nối, bạn có thể chọn tên nào cũng được.

Một danh sách các dịch vụ cloud xuất hiện, hãy chọn số 13, Google Drive rồi nhấn Enter.

Ở 2 dòng tiếp theo Client ID và Client Secret bạn hãy để trống nhấn Enter.

Mục Scope that rclone should use when requesting access from drive chọn 1 – drive

Tiếp theo, để trống với ID of the root folder và Service Account Credentials JSON file path

Khi được hỏi Use auto config? hãy nhập n rồi nhấn Enter. Ngay lập tức, Rclone sẽ đưa ra một đường link, bạn có thể click thẳng vào đó hoặc copy rồi paste vào trình duyệt

Giao diện sẽ xuất hiện như sau:

Nhấn nút Allow để đồng ý, sau đó bạn sẽ nhận được đoạn mã verification code như hình dưới:

Quay trở lại cửa sổ SSH, copy rồi paste code này vào dòng Enter verification code> rồi nhấn Enter.

Chọn n tức no đối với Configure this as a team drive?

Rclone cần xác nhận thông tin một lần nữa, bạn nhấn y để đồng ý rồi nhấn q để thoát khỏi giao diện cấu hình kết nối.

Vậy là xong, giờ bạn có thể test với lệnh liệt kê thư mục trong kết nối remote
# rclone lsd remote:

3. Tạo file script backup

Tạo file backup.sh ở thư mục /root/

nano /root/backup.sh

Copy toàn bộ nội dung script bên dưới rồi paste vào

# Partner - Tu dong backup website CyberPanel toi Google Drive

#!/bin/bash

SERVER_NAME=BACKUP_WEB_BY_PARTNER

TIMESTAMP=$(date +"%F")
BACKUP_DIR="/root/backup/$TIMESTAMP"
MYSQL=/usr/bin/mysql
MYSQLDUMP=/usr/bin/mysqldump
SECONDS=0

mkdir -p "$BACKUP_DIR/mysql"

echo "Starting Backup Database";
databases=`$MYSQL -e "SHOW DATABASES;" | grep -Ev "(Database|information_schema|performance_schema|mysql)"`

for db in $databases; do
$MYSQLDUMP --force --opt $db | gzip > "$BACKUP_DIR/mysql/$db.gz"
done
echo "Finished";
echo '';

echo "Starting Backup Website";
# Loop through /home directory
for D in /home/*; do
if [ -d "${D}" ]; then #If a directory
domain=${D##*/} # Domain name
echo "- "$domain;
zip -r $BACKUP_DIR/$domain.zip /home/$domain/public_html/ -q -x /home/$domain/public_html/wp-content/cache/**\* #Exclude cache
fi
done
echo "Finished";
echo '';

size=$(du -sh $BACKUP_DIR | awk '{ print $1}')

echo "Starting Uploading Backup";
/usr/sbin/rclone move $BACKUP_DIR "remote:$SERVER_NAME/$TIMESTAMP" >> /var/log/rclone.log 2>&1
# Clean up
rm -rf $BACKUP_DIR
/usr/sbin/rclone -q --min-age 2w delete "remote:$SERVER_NAME" #Remove all backups older than 2 week
/usr/sbin/rclone -q --min-age 2w rmdirs "remote:$SERVER_NAME" #Remove all empty folders older than 2 week
/usr/sbin/rclone cleanup "remote:" #Cleanup Trash
echo "Finished";
echo '';

duration=$SECONDS
echo "Total $size, $(($duration / 60)) minutes and $(($duration % 60)) seconds elapsed."

Nhấn Ctrl+O, Enter để lưu và Ctrl+X để thoát.

Phân quyền cho script
chmod +x /root/backup.sh

Vậy là xong rồi đó, giờ bạn có thể test lại bằng cách chạy lệnh:
/root/backup.sh

Thử kiểm tra trên Cloud xem có thư mục mới với dữ liệu backup chưa nhé, hoặc test với lệnh:
rclone lsl remote:BACKUP_WEB_BY_PARTNER

4. Tạo cronjob tự động backup hàng ngày

Giờ mình sẽ cho script tự động chạy lúc 2h00 sáng.

EDITOR=nano crontab -e

Dán nội dung sau vào cửa sổ Terminal

0 2 * * * /root/backup.sh > /dev/null 2>&1

Nhấn Ctrl+O, Enter để lưu và Ctrl+X để thoát

Vậy là xong, cứ 2h sáng hàng ngày script sẽ tự động chạy, backup toàn bộ dữ liệu của VPS rồi upload lên Google Drive. Đồng thời, dữ liệu backup trên VPS sẽ được xóa luôn sau khi upload xong.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using ‘Content here, content here’, making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for ‘lorem ipsum’ will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of “de Finibus Bonorum et Malorum” (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, “Lorem ipsum dolor sit amet..”, comes from a line in section 1.10.32.
