SQL 2012 AlwaysOn High Availability, how to collect Backup history across replicas from MSDB
During our implementation of a synchronised SQL Server AlwaysOn solution, with one primary and two replica,
we ran into a challenge on how to merge backup history from the involved MSDB databases.
We take full and diff backup on primary and log backup on preferred replica.
To get the full chain of backup history, we need to merge backup history from all servers running the backups at any given time.
How do we solve this?
We consider to create a procedure to move backup history from all involved MSDB databases to a common central database.
Backup tools like Quest LiteSpeed offer a solution, with a local and central repository.
Also Oracle has a solution for saving backup history local and centralised.
I Except, like sql2012 truncating a logbackup across replicas, I really expect from Microsoft at simple
solution viewing the Last backup history would be out of the box.
