Hi,
We are currenly using AlwayOn (SQL Server 2016 Ent) backup preference to Primary Replica.As per Microsoft Diff backup doesn't support on Secondary Replicas.
But in order to reduce load on primary we are planning to run backups in Secondary, but due to this limitation we are in big confusion and we can't avoid Diff backups.
These DB's are very critical and should run 24/7.
In this case what is the alternative?
