Hello guys,
On my site, I have a set of big databases (+6TB total) that is running on a SQL Server 2012 instance. One of these is the main DB and the other ones are archived data that are queried sometimes (unions on the main dbs stored procedures) but do not have to be 24/7 online. Only the main db is mirroed to another datacenter because of storage constraints.
To mantain all this there is a job that keep moving old data from the main to the archive dbs, but this is slow and ineficient. I plan to improve all that with a sliding window paritioning solution but I couldn't find a way to switch an archived partition or table to another database without data movement.
I can put everything on a single database but I couldn't find an HA solution that I could choose the objects that actually need the high availability.
I'm currently doing some tests with replication but it will be tricky to pull it off and it is not a true HA solution.
Any ideas on how I can parition my data but only provide HA to a subset of the data?
Thanks in advance;
