[筆記] UBUNTU 16.04 Google Compute Engine 自動自我備份

以下步驟將教學利用Google Compute Engine 自我定期備份(Backup automatically):

1. 安裝 Google Cloud ( 如果用外部機器才需要裝,如果使用Google Compute Engine內建已安裝)

# Create an environment variable for the correct distribution
export CLOUD_SDK_REPO="cloud-sdk-$(lsb_release -c -s)"

# Add the Cloud SDK distribution URI as a package source
echo "deb $CLOUD_SDK_REPO main" | sudo tee -a /etc/apt/sources.list.d/google-cloud-sdk.list

# Import the Google Cloud Platform public key
curl | sudo apt-key add -

# Update the package list and install the Cloud SDK
sudo apt-get update && sudo apt-get install google-cloud-sdk

2. 開啟該Instance的Cloud Engine API權限

# 如果還沒開機器可以再開機器的時候設定,已經開了就要停止機器用「編輯」做設定,須將Compute Engine的權限開啟為「讀寫」


找到Compute Engine開啟讀寫,其餘不需更動

3. 撰寫Script sh檔自動建立Snapshot並刪除昨日的Snapshot

# 新增一個執行檔
cd /home
sudo vim

# 內容如下:主要是將昨日日期與今日日期標記在snapshot名稱
yesterday="$(date -d yesterday '+%Y%m%d')"
nowDate=$(date +%Y%m%d)
sudo gcloud compute disks snapshot [GOOGLE CLOUD ENGINE DISK NAME] --snapshot-names=backup-$nowDate --zone=asia-east1-a
gcloud compute snapshots delete backup-$yesterday

# 將執行檔轉為可執行
sudo chmod +x

4. 將sh設定到Crontab中
sudo vim /etc/crontab

# 內容如下:看是要什麼時候執行該備份,以下為定期每日凌晨一點執行
0 1  * * * root /home/
