Cloud archiving involves moving project files you no longer actively use, but may need later, from local computers or servers to online cloud storage services. Unlike active cloud backups which focus on frequent updates for disaster recovery, archiving prioritizes long-term, cost-effective storage for retrieval over months or years. This offloads older data, freeing valuable local space while still maintaining access when required, often through simplified web portals or sync clients.

Industries like media production commonly archive raw footage and past projects, while software teams preserve legacy code versions. Tools used include integrated sync clients (like Google Drive File Stream) for seamless transfer, specialized archive tiers within platforms (e.g., AWS Glacier Deep Archive), or dedicated archive management software that automates selection and transfer based on project age or status.

The key advantages are immense scalability, reduced local infrastructure costs, and enhanced protection against local disasters like hardware failure or fire. Limitations include internet dependency for access/restores, potential egress fees to retrieve large volumes, and long-term cost viability analysis. Ethical considerations involve ensuring robust security (encryption) and adherence to data residency regulations. Future trends focus on smarter AI-driven tiering based on file content and predictive retention policies.
