How to Configure Object Storage Cross-Region Replication for Disaster Recovery
Introduction Oracle Cloud Object Storage is a regional service, i.e., objects are stored in a specific Oracle Cloud region. You can enable cross-region replication to automatically sync your data to a remote region for redundancy, providing protection from a regional outage. This blog post describes how to configure cross-region replication, use the replicated Object Storage…
Ensure Disaster Recovery by replicating Automatic Backups across Regions in Oracle Cloud
Introduction Before we start, I want to mention that Oracle (Active) Data Guard provides the best disaster recovery solution for Oracle Databases with zero data loss and minimal recovery time. Restoring from backup usually comes with a much higher RPO and RTO than what Data Guard provides. However, if restoring from backup satisfies your application’s…
Three Ways to Use Backups for Disaster Recovery across Regions in Oracle Cloud
Introduction Oracle Data Guard provides zero or near zero data loss and a recovery time of just a few minutes. For unrecoverable failure, a restore from backup usually takes hours and restores your data to the last backup. If you have applications that tolerate the RTO and RPO provided by a restore from backup, having…
Fast-Start Failover in Data Guard Environments on Oracle Cloud
Introduction Oracle Data Guard and Active Data Guard ensure high availability and disaster recovery during maintenance operations and in case of outages. Recovery Point Objective (RPO) of zero (zero data loss) can be achieved by setting up SYNC or FASTSYNC replication, even at any distance, using Far Sync without compromising performance. Recovery Time Objective (RTO)…
How to measure Network Latency for Oracle Data Guard Replication
Introduction Oracle Data Guard replicates data from the primary to one or multiple standby databases for high availability and disaster recovery. The decision to transfer the redo synchronously or asynchronously depends on your RTO and RPO. Synchronous redo transport provides zero data loss and lower recovery time, but your application needs to wait until the…
Three Ways to backup your Oracle Cloud Databases to Object Storage
Introduction Oracle Cloud provides you the option to enable automatic backups with the click of a button. In case you have different backup requirements, you still have the flexibility to create your manual backup configurations and create your backups via command-line tools or directly using RMAN. This applies to VM DB Systems, Exadata Cloud Service,…
Restore DBCS VM Databases from Automatic Backup across Availability Domains
Update August 7th, 2023: now it’s possible to create a database from backup across Availability Domains in the same region using Cloud Tooling for BaseDB and ExaDB-D. Introduction Oracle Cloud VM DB Systems provide fully automated backups that can be enabled by the click of a button. The backups are stored in an Oracle-managed bucket.…
Restore a TDE encrypted Cloud Database Backup to another Availability Domain, OCI Region, or On-Premises
Introduction Oracle Cloud databases provide fully automated backups that can be enabled by the click of a button. However, the backups are stored in an Oracle-managed bucket. Hence, the automatic backups can only be used to restore on the same database host or create a new database in the same availability domain. If you want…
High Availability & Disaster Recovery in Oracle Cloud Infrastructure
Critical applications have the requirement to run 24/7 and tolerate hardware and software failure and even complete data center outages. Oracle Cloud Infrastructure with its’ regions, Availability Domains (AD), and Fault Domains (FD) provides the needed building blocks to design and run high availability and disaster recovery architectures for your applications and databases. A region…
