The Most Valuable SQL Server DBA Experts to Follow (Modern DBA Focus)
Introduction: Why Following the Right SQL Server Experts Matters

Key DBA Lessons from These Experts
Across all these experts, the core principles of SQL Server administration are consistent:
1. Backup is Everything, Always test restores, Use automated jobs, Keep offsite backups
2. Maintenance is Not Optional, Index rebuild/reorganize, Update statistics
Check corruption
3. Security Must Be Proactive, Least privilege access, Encryption (TDE), Audit and monitoring
4. HA/DR is Business Survival, Always On Availability Groups, Log shipping, Failover clustering
5. Monitoring is Continuous, Use scripts and tools, Track waits, CPU, IO; Detect issues early
Reality Check from DBA Community
Real-world DBA discussions emphasize:
Always verify backups, security access, and monitoring first before anything else
This aligns perfectly with what top experts teach.
