How to restore instance using snapshot in Google Compute Engine?

问题

I created a snapshot of a VM instance via cloud console. I would like to know how I can restore an instance using a snapshot. The documentation for compute engine is not very helpful. The instance runs on Ubuntu. Thanks.

回答1:

To restore an instance from a snapshot without deleting/re-creating the instance:

1. Shut down the instance and detach the boot disk: gcloud beta compute instances detach-disk INSTANCE_NAME --disk BOOT_DISK_NAME

2. Create a new disk from the snapshot: gcloud compute disks create DISK_NAME --source-snapshot SNAPSHOT_NAME

3. Attach the disk created from step 2 as the boot disk: gcloud beta compute instances attach-disk INSTANCE_NAME --disk DISK_NAME --boot

Restoring the instance without deleting/re-creating the instance means that after restore, the instance will keep its IP address and other properties like tags, labels, etc.

Try using:

gcloud compute disks \
create <NEW_INSTANCE_NAME> \
--source-snapshot <SNAPSHOT_NAME> \
--type pd-ssd \
--zone <ZONE>

You could find useful instruction here.

In Console, you can go to VM Instances from Compute Engine tab. There you click on '+Create Instance' and there in section of boot-disk, you can navigate to 'snapshots' tab and select the snapshot you took.

Like this from console, you can Restore your instance.

Let me know, if this doesn't work for you!
