Long-term data retention up to 10 years: Announcing Private Preview of Azure Backup for Azure Cosmos DB

Hans Wieser [MS]
Principal Product Manager

Azure Backup for Azure Cosmos DB is a new option that lets you securely protect and recover your Azure Cosmos DB data for compliance, audit, and ransomware protection scenarios. It leverages Azure Backup’s vault isolation and Azure Cosmos DB’s native backup streams to deliver scalable, long-term data protection that meets regulatory requirements.

How does it work?

During the private preview, you can configure backup schedules and retention policies at the Azure Cosmos DB account or collection level, stream backups to a vaulted, isolated Azure Backup Vault, and restore data to an empty Azure Cosmos DB account in the same region. The service supports flexible policy assignments, role-based access control, and monitoring through Azure Backup Center.

You can define policies to capture the date and time when to take the LTR backup, as well as the storage resilience and retention time
Define backup policies to specify time, storage resilience and retention time

Why is it important?

Azure Cosmos DB LTR helps organizations meet strict regulatory requirements like GDPR, FINRA or DORA by providing immutable, auditable long-term backups. This ensures your critical data remains immutable and recoverable, addressing legal hold and time lock scenarios dictated by legal and industry compliance needs.
