If you cannot run online HA (Oracle Data Guard, SQL Server Always On Availability Groups, MySQL InnoDB cluster) then SRM may be a viable alternative.

Online HA provides faster failover and minimal data loss but SRM excels at end-to-end recovery orchestration. i.e. if you need to keep the content of your database in sync with files held on a different server then SRM may help you avoid situations where the database ends up with a pointer to a file that was lost during the failover.

• Prefer Always On replication over SRM for SQL Server

• Use SRM only for complete disaster recovery scenarios

• Never run both replications simultaneously for same databases

• Test failover procedures regularly

• Monitor both storage and database replication health

• Have clear recovery procedures documented

• The primary risk with SRM + Always On is the potential for data inconsistency and split-brain scenarios.

• Always On's database-level replication is generally more reliable for SQL Server than storage-level replication.
