When a SQL Server database crosses the 1TB mark, several operational practices need to change. Key steps include auditing largest objects and dropping unused indexes to reclaim space, analyzing top queries by reads and considering read-only replicas, offloading CHECKDB to AG secondaries or restored copies, planning for storage snapshot backups before hitting 2-5TB, timing test restores and running DR drills, documenting current RPO/RTO with a formal worksheet, tracking backup size growth over time, and upskilling developers on query and index tuning to prevent further technical debt accumulation.
