How can you leverage RDBMS latest trends to improve disaster recovery?

Yes. trend is to move on cloud but with right decision and assessment. Moving to cloud is having many background exercises like cloud compatibility of the related applications. Whether to move for Azure Database or AWS RS or lift and shift the VMs on cloud needs backend decision makings. Once we are done with all these assessments then we are good to take advantages of cloud features including region or AZ based HA/DR, autoscaling and replications. Once we are good to with the potential latency or negligible performance degradation compared to on prem data centres then cloud is Pandora box for new age technology.

Continuous backup and replication have emerged as game-changer for safeguarding your relational database management system(RDBMS). These techniques ensure that your data remains protected and accessible even in the face of unexpected disruptions. * Minimized data loss* Improved recovery point objective (RPO)*Reduced recovery time objective (RTO) In SQL Server we can schedule backups and configure replication which provides us the ability of no data loss in cases of any failures. Like Transaction log backups, Tail Log backups. Always On is a feature introduced in SQL Server 2012 where we can set multiple replicas (multiple secondary server) where database will be in sync so in case of any failure, we can run the show from secondary servers.

RDBMS technology is getting modernised day by day, there is drastic difference between the RDBS in the 90s and now. I still remember when to take a mssql db backup, we used to create a backup device first then followed by actual db backup. But with the new versions and features are getting added database backup is just an easy affair. RTOs and RPO have came down to almost real time now. Whether it is on prem or cloud, contineuos backup with different cycles are just on finger tips helps to achieve customer expectation.

With the help of new and updated MSSQL DMVs which can run through MSSQL agent jobs periodically, helps in automatically improves the database and mssql performance or db queries overall. I think this helps a DBA as well wherein he can concentrate on other productive activities like providing value adds to the customer environment, driving system improvement programs. There is drastic improvement in performance degradation when we compare the latest Oracle or MSSQL versions to the versions of MSSQL 2000 or Oracle 8i/9i. Database outages due to corruption or performance degradation have almost became a history where DBA used to invest lot of time.
