The following table explains how Google Cloud charges for network egress (data transfer), depending on the location option you select, and the region from which you retrieve the snapshot. Saving a snapshot to a regional location means the snapshot will be stored in one region only, and allows you to choose the specific region it will be stored in. Regional location -this is one specific Google Cloud region (for example, asia-east1).Saving a snapshot in a multi-regional location means the snapshot will be replicated across multiple regions. Multi-regional location -this is an entity that represents a large region such as a continent (for example “Asia”), and includes several Google Cloud regions (asia-east1, asia-east2, asia-northeast1, asia-northeast-2).You can choose between two storage location options when saving a snapshot:

Snapshots are stored in Google Cloud Storage. Source: Google Cloud Platform Google Cloud Snapshot Considerations: Storage Location and Network Costs The difference between storage snapshots and backups is that snapshots are point-in-time copies of an entire disk while backups can contain individual files from multiple locations. A snapshot is an incremental copy of your data-the first snapshot contains all the data, while the next snapshots only save data blocks that changed in the interim. Google Cloud lets you take snapshots of persistent disks attached to your instances.
