能否完整保存Google Cloud Platform控制台创建的项目并后续恢复？

Hey there! Let's walk through exactly how you can fully backup your GCP project—including users, permissions, settings, and all components—before shutting it down, especially since you're new to the Cloud SDK tools. I'll break this down into actionable steps that fit your use case:

一、先快速搞定gsutil/gcloud配置 #

Since you haven't got gsutil working yet, let's fix that first—it's simpler than you think:

• Download and install the Google Cloud SDK for your operating system (you can grab it directly from the GCP Console's SDK setup page)
• Open a terminal and run gcloud init, then follow the wizard: log in with your GCP account, select the project you want to backup, and set a default region/zone (optional)
• That's it! gsutil will automatically be configured to work with your account and project after this—no separate setup needed.

二、备份项目核心权限与设置 #

This is the part you're missing right now: capturing users, roles, and project-wide configurations.

1. IAM Permissions (Users, Roles, Service Accounts) #

This command exports every user, service account, and their assigned roles into a JSON file:

gcloud projects get-iam-policy YOUR_PROJECT_ID --format=json > iam-policy-backup.json

• Save this file safely—when you restore, you can run gcloud projects set-iam-policy NEW_PROJECT_ID iam-policy-backup.json to instantly reinstate all permissions.
• Note: Service accounts are included in this policy, but if you're using service account keys locally, be sure to download and backup those key files from the GCP Console (IAM > Service Accounts > Keys tab).

2. Enabled APIs List #

Don't forget to backup which APIs are enabled in your project—re-enabling them one-by-one later is a hassle:

gcloud services list --enabled --project YOUR_PROJECT_ID --format="value(config.name)" > enabled-apis.txt

To restore, use this quick bash script to enable all APIs at once:

for api in $(cat enabled-apis.txt); do
  gcloud services enable $api --project NEW_PROJECT_ID
done

3. Project Metadata (Labels, Description, Default Settings) #

Export basic project details like labels, description, and billing info (if needed):

gcloud projects describe YOUR_PROJECT_ID --format=json > project-metadata.json

When restoring, you can pull values from this file to update your new project with gcloud projects update NEW_PROJECT_ID --labels=... or --description=....

三、补充完善你已备份的组件 #

You've already backed up MySQL and Cloud Functions—here's how to make those backups complete:

1. Cloud SQL (MySQL) #

Beyond the database data, export the instance's configuration (machine type, storage size, backups settings, etc.):

gcloud sql instances describe YOUR_INSTANCE_NAME --project YOUR_PROJECT_ID > sql-instance-config.json

When restoring, use this file as a reference to recreate the instance with identical settings, then import your existing database backup.

2. Cloud Functions #

Backup more than just the code—capture triggers, environment variables, and resource limits:

gcloud functions describe YOUR_FUNCTION_NAME --project YOUR_PROJECT_ID --format=json > function-config.json

• Download the function code to local storage: gcloud functions get-source YOUR_FUNCTION_NAME --destination ./function-source
• To restore, deploy from your local code with gcloud functions deploy, then use the values in function-config.json to set triggers, environment variables, and memory limits.

四、 Backup for Other Common Components (If Your Project Uses Them) #

If you have additional services in your project, add these steps:

• Cloud Storage Buckets: Sync all bucket contents to local storage with:

  # List all buckets in your project
  gsutil ls gs:// | grep YOUR_PROJECT_ID > buckets-list.txt
  # Sync each bucket to a local folder
  for bucket in $(cat buckets-list.txt); do
    gsutil -m rsync -r $bucket ./local-backup/$bucket
  done
  

  The -m flag enables multi-threading for faster transfers.
• Compute Engine Instances: Create a disk snapshot, export it to Cloud Storage, then download to local:

  # Create a snapshot of your VM's disk
  gcloud compute disks snapshot YOUR_DISK_NAME --snapshot-names YOUR_SNAPSHOT_NAME --project YOUR_PROJECT_ID
  # Export snapshot to Cloud Storage
  gcloud compute snapshots export YOUR_SNAPSHOT_NAME --destination-uri gs://YOUR_BUCKET/snapshot-export.tar.gz --project YOUR_PROJECT_ID
  # Download to local
  gsutil cp gs://YOUR_BUCKET/snapshot-export.tar.gz ./local-backup/
  

五、 Critical Notes for Shutdown and Restoration #

• Before shutting down: Double-check that all backup files are saved locally and verify their integrity (e.g., open the JSON files to ensure they contain data, check local file sizes match Cloud Storage bucket sizes).
• Shutting down the project: Use the GCP Console to select "Shutdown" for your project. Keep in mind: GCP retains deleted projects for 30 days, but after that they're permanently erased—so don't rely on this recovery window; your local backups are your safety net.
• Restoring in 6 months:
  1. Create a new GCP project (you can reuse your old project ID if it's still available, otherwise use a new one).
  2. Reverse the backup steps: first configure project metadata, enable APIs, restore IAM permissions, then recreate each component (Cloud SQL, Functions, Storage) using your local backups.
