Zero Data Loss Protection for Oracle on Azure

Azure Tessell for Oracle is a PaaS that manages the lifecycle of Oracle databases on Azure, covering provisioning, HA, DR, patching, and backup. This guide focuses specifically on the backup and recovery layer, walking through the three mechanisms Tessell supports: snapshot-based backups, archive log backups, and RMAN backups. It is a technical reference walkthrough with portal screenshots, configuration details, and Azure storage policies that support immutability and ransomware protection. Each section explains how the backup type works, what Azure storage tier it uses, and how it integrates with Tessell Dataflix for point-in-time recovery.

What is inside

• Overview of Azure Tessell for Oracle's lifecycle capabilities, spanning provisioning, automated HA and cross-region DR, patching, monitoring, and chargeback insights

• Snapshot-based backups built on Azure Managed Disks, with Oracle-aware snapshots equivalent to an L0 RMAN backup for the lowest RTO

• Archive log backups taken every 5 minutes across four Azure redundancy tiers (LRS, ZRS, GRS, GZRS) with immutability through Azure blob versioning and retention policies

• RMAN backups stored on immutable blob containers, portable for restore to other Azure regions, AWS, GCP, on-premises data centers, or VMware environments

• Time-based retention policies that Tessell locks within 24 hours of creation, supporting regulatory and compliance requirements

• Recovery through Tessell Dataflix, which combines snapshots, archive logs, and RMAN backups for point-in-time restores and redacted downstream environments

Who is this for

Oracle DBAs, database architects, and IT leaders responsible for backup, recovery, and compliance posture of Oracle workloads running on Azure. The guide walks through how Tessell layers snapshot, archive log, and RMAN backups on top of Azure Managed Disks and Blob Storage, and how each contributes to ransomware protection. A capabilities overview for backup, recovery, and compliance planning. For configuration specifics, refer to the Tessell product documentation.
