Google Cloud Coldline Storage

What is Google Cloud Coldline Storage?

Google Cloud Coldline Storage is a public cloud cold storage service for infrequently accessed data. It is specifically designed to store data that organizations access once a quarter.

The Coldline service requires a 90-day minimum storage duration. It provides slightly lower availability than other storage classes, with only 99.95% in multi-regions and dual-regions, as well as 99.9% in regions.

Google Cloud Coldline is one of four cloud storage classes within the Google cloud storage platform. The other three classes are the following:

  • Google Cloud Standard Storage. For frequently accessed data, also known as "hot data."
  • Google Cloud Nearline Storage. For infrequently accessed data and a 30-day minimum storage duration.
  • Google Cloud Archive Storage. For data archiving, online backup and disaster recovery with a 365-day minimum storage duration.
