Google Compute Engine - Disks Export Tool
Export Google Cloud instances disks in your favorite format and store in Cloud Storage.
Supported image formats are vmdk (default), vhdx, vpc, vdi, and qcow2.
How script works
- Selects all disks on your current Google Project
- Creates a new image for each selected disk
- Stores all images in a Google Storage bucket
- Removes all images from Google Cloud
You can run the script from your bash console or from Google Cloud Shell.
You need login in Google Cloud SDK before running script, for a fast execution run it in Cloud Shell
Script will ask you disk to export or if you want to export all available disks.
Requirements
- Google Cloud SDK
- gcloud
- gsutil
- alpha commands
- Bash CLI
Export disks
Before running the script create a new bucket on Google Storage, make sure you have set right permissions on bucket.
$ ./gce-disks-export BUCKET_NAME [IMAGE_FORMAT]
# Without format, use vmdk as default
$ ./gce-disks-export my-bucket-name
# Export as qcow2 image format
$ ./gce-disks-export my-bucket-name qcow2
Cloud Build Activation
Image export requires Cloud Build API activation, if you haven’t already done, script will ask you to activate it.

Google Storage
Based on Storage class of your bucket and your images access requirements, you can save monthly cost.

- Multi-Regional
- Regional
- Nearline
- Coldline
Multi-Regional Storage
- > 99.99% typical monthly availability
- Geo-redundant
- Storing data that is frequently accessed
- Data stored in dual-regional locations
Regional Storage
- 99.99% typical monthly availability
- Data stored in a narrow geographic region
- Storing frequently accessed data in the same region
Nearline Storage
- 99.95% and 99.9%, typical monthly availability in multi-regional and regional
- Very low cost per GB stored
- Data you do not expect to access frequently (i.e., no more than once per month)
Coldline
- 99.95% and 99.9%, typical monthly availability in multi-regional and regional
- Lowest cost per GB stored
- Data retrieval costs
- Higher per-operation costs
- 90-day minimum storage duration
- Data you expect to access infrequently (i.e., no more than once per year)
