Key choices to make when DB2 HADR is setup(DB2 LUW High availability) With HADR, you base the level of protection from potential loss of data on your configuration and topology choices. Some of the key choices that you must make are as follows: What level of synchronization will you use? Standby databases are synchronized with the primary database through log data that is generated on the primary and shipped to the standbys. The standbys constantly roll forward through the logs. You can choose from four different synchronization modes. In order of most to least protection, these are SYNC, NEARSYNC, ASYNC, and SUPERASYNC. Will you use a peer window? The peer window feature specifies that the primary and standby databases are to behave as though they are still in peer state for a configured amount of time if the primary loses the HADR connection in peer state. If primary fails in peer or this "disconnected peer" state, the failover to standby occurs with zero data loss. This feature provides the greatest protection. How many standbys will you deploy? With HADR, you can use up to three standby databases. With multiple standbys, you can achieve both your high availability and disaster recovery objectives with a single technology.

S3 Multi-Region Access Points Provide a global endpoint that applications can use to fulfill requests from S3 buckets that are located in multiple AWS Regions. There mostly used management console than CLI. - Created Multi-region Access Point - Setup Replication and failover rules (in our cases there was 3 bucket in 3 regions and we've setup two-way replication) - Applied replication rule to all objects (there is an ability to strict the scope of objects that could be replicated) - After configuring MRAP you could put object directly to it's ARN (not to specific buckets that are parts of it). To list your Multi-Regional Access Points aws s3control list-multi-region-access-points --account-id account == Cross-account S3 Replication and Multi-Region Access Points S3 Multi-Region Access Points can be used for disaster recovery. Cross-account support in Multi-Region Access Points enables seamless failover to a second account. This section passed only theoreticaly as I have no second account, the approach is the same as on before modules the only difference in the principals and IAM Role definitions

I'm thrilled to share a recent milestone in our database management journey. We've successfully enhanced our SQL Server infrastructure, achieving both high availability and disaster recovery in a streamlined setup. 🔗 Key Highlights: Windows Failover Cluster: Configured a two-node Windows Failover Cluster. This setup ensures continuous availability and minimal downtime, a critical factor in our operational efficiency. Always-On Availability Group: Integrated an Always-On Availability Group to this cluster. This advanced feature of SQL Server not only provides high availability but also enables a seamless failover environment. Read-Only Node Synchronization: Added a third SQL Server node, synchronized as read-only with the primary node. This was achieved through meticulous log shipping, enhancing our data reporting and offloading capabilities. Disaster Recovery: To safeguard against unforeseen events, we've also configured Disaster Recovery (DR) for the entire setup, again utilizing log shipping. This DR strategy ensures data integrity and business continuity under any circumstances. The Outcome: Improved system reliability and data availability. Enhanced performance for read-intensive operations. A robust disaster recovery plan, ensuring business resilience. This accomplishment marks a significant step forward in our commitment to maintaining a state-of-the-art IT infrastructure. #SQLServer #HighAvailability #DisasterRecovery #TechInnovation #ITInfrastructure

🚨 Real-World IT Recovery Insight! 🚨 Last week, I found myself in the thick of a real test for our disaster recovery procedures at a major manufacturing site. We faced a production stopping issue when a legacy Oracle RDB database running on OpenVMS became corrupt. This impacted custom applications and critical business sub-systems, which ultimately led to a stop of production. This experience was a powerful reminder of why we rigorously test our procedures and maintain robust disaster recovery plans. Despite the stressful scenario, we managed to minimise data loss and get everything back up and running within five hours—avoiding massive downtime costs in an environment where every minute counts. Here’s what we’ve reinforced: 🔵 Backups Are Essential: Regular and systematic backups are absolutely crucial for protecting critical data. Yes, that includes special backups for databases! 🔵 Procedure Matters: Having a clear and tested restoration procedure means when things do go wrong, we can make them right quickly and efficiently. 🔵 Proactive Testing: It’s not enough to have backups—they need to work when it counts. Regular testing of these systems is key. Take it from me—always be ready to put your disaster recovery plans to the test. Because when crunch time comes, you'll want to be sure they can handle the pressure! #ITRecovery #DataProtection #RiskManagement #BusinessContinuity #OracleRDB #OpenVMS
