Cost-Effective Disaster Recovery Strategy with Tessell’s Data Access Policies (DAP)
Blog post from Tessell
Ensuring data availability and integrity is crucial, and traditional disaster recovery (DR) solutions often involve significant costs associated with infrastructure and database licensing. A more cost-effective alternative is using Tessell’s Data Access Policies (DAP) to implement a cross-region Point-In-Time Recovery (PITR) policy, which enables continuous data replication without maintaining a live DR database. This approach allows for substantial savings by eliminating the need for live infrastructure and associated licensing fees, especially for databases like Oracle. Regular snapshots and transaction logs are stored in object/blob storage, ensuring data is continuously updated and can be reconstructed to a recent state in the event of a failure, minimizing data loss (RPO=0). Although creating an on-demand clone introduces some recovery time (RTO), the cost benefits and zero data loss potential often outweigh this consideration. This strategy, dubbed "Poor Man’s DR," offers a scalable and flexible disaster recovery solution that ensures data security and business continuity while being financially sustainable for organizations.
