Google is not a service used for backup or long-term archival. DIT has backup services for scheduled backup services, with a defined retention policy and long-term archival storage, at a reasonable cost. Backup services will generally do the following things.

Archive and Long-term Retention Storage services are also primary storage services, but due to the nature of the data, provide a measurably reduced time to store and retrieve data. Depending on the business policy, archive data can also be subject to expiration dates. However, the services below will not enforce retention policies. It will be up to the customer to develop a mechanism to enforce retention according to the University records schedule.
When selecting an Archive or Long-term Retention Storage Service, select a service that best meets your workflow and cost requirements. Cloud archive services such as Amazon S3 Glacier Deep Archive often require manual workflows and reduced access times that may cost more in administration and management than a tiered storage service such as the Networked Storage Service. Similarly, the Networked Storage Service may be cost-prohibitive for large datasets that would benefit from manual efforts to move static data to more cost-effective services.
| Category | Networked Storage Service | AWS S3 Glacier Deep Archive | Google Cloud Storage |
|---|---|---|---|
| Use case | Automated tiered archiving for production workflows for any data type. Recommended for data that needs to be accessed spontaneously and for customers who are constantly referencing data sets. | If your department has an AWS account, you can set up S3 buckets to archive to Glacier Deep Archive. This is recommended for large, static data sets. |
Long term File storage in object-based storage. Good for:
Cloud Storage Options | Google Cloud Coldline Storage: Very low cost. Good for data that can be stored for at least 90 days, including disaster recovery. Archive Storage: Lowest cost. Good for data that can be stored for at least 365 days, including regulatory archives. |
