I'm considering changing the SQL Server differential backup interval for simple recovery databases from every 2 hours to every 4 hours with one daily full backup. A four hour data loss is acceptable per SLA. Considering SQL Server will automatically issue checkpoints, log clearing will continue and doesn't appear to be a concern at this point. Before making this change should I monitor data churn or checkpoint occurrences? Thus far I'm thinking this is truly a RPO/SLA concern or issue. Let me know if I'm missing anything.
Thanks in advance!!!
