CloudM Archive: Google Cloud Storage (GCS) Costs

CloudM Archive uses your own Google Cloud Platform (GCP) environment to store data. Therefore, all storage-related charges are billed directly to you by Google.

Cost Drivers

Your total cost is determined by three main factors:

1. Storage Costs: The monthly cost of hosting the data. This depends on the volume of data and the Storage Class selected.
2. Network (Egress) Costs: Charges for transferring data out of Google Cloud.
   • Note: Egress charges are typically minimal unless you are restoring very large amounts of data. See Google's Network Pricing for details.
3. Operations Costs: Charges for specific actions performed on the data, such as listing files, writing (inserting) files, or checking file integrity (get).

Operations Breakdown (Class A & B)

CloudM Archive performs specific "Class A" (heavy) and "Class B" (light) operations during the archiving process. Each GCS account typically includes a free quota of operations per month, but heavy usage may incur charges.

Class A Operations

• storage.*.insert:
  • 1 per User File (creation).
  • 2 per Email/File (1 for the blob file, 1 for the JSON metadata).
• storage.*.list:
  • 1 per 1,000 already migrated items (emails, chats, appointments) to check for duplicates.

Class B Operations

• storage.*.get:
  • 1 per Email/File (to verify the MD5 checksum immediately after upload).

Example Scenario

To help you estimate costs, here is a breakdown of the operations required to archive a single user who has 1 Email and 1 Drive File (assuming no data has been archived previously):
