Hello, We have to set up AlwaysOn and I have heard that there is some issues when using the Data Synchronization option of FULL and allowing SQLServer to perform the backup and restore of the database and log backups when it comes to LARGE databases. My question is what is considered LARGE for this operation.? Many people have different ideas as to what is a large database size. So anyone have experience or best practices when it comes to database in the size of 400GB when setting up AlwaysOn and doing the synchronization using the FULL option when you get to the Select your data Synchronization preference. We have 15 databases and 3 replicas each to perform the synchronization on and would like to do as much automated as possible instead of all manual backups and restores.
