Why Filegroup Level Restores Don’t Solve This Problem If there are any issues with the data load, restore over the filegroup from the READ_ONLY backup.Set the MONTHLYTABLES filegroup as READ_WRITE.
Take a filegroup level backup of MONTHLYTABLES.Whenever we need to load data into the filegroup, we plan to: Move the monthly tables into a filegroup named MONTHLYTABLES.In Enterprise Edition, SQL Server also has the ability to have the Primary and select other filegroups online and responding to queries while you are restoring individual filegroups.įor situations like this, it seems like filegroup level backups and restores will be the answer to our problem. In SQL Server we have the ability to back up and restore individual filegroups. Restoring the entire database takes a long time, and might remove changes to the “daily” tables as well. When this occurs, the recommended procedure is to reset the monthly tables to the state they were in prior to the monthly load job beginning, and restart the process. Periodically, the monthly load will fail due to issues outside of SQL Server. The tables updated once per month are updated by a legacy application and you don’t have access to the source code. Some tables are updated daily in ImportantDB, and other tables are only updated once per month. Let’s say you manage a database named ImportantDB. Our Problem: We Need to Restore the Data for Some of the Tables in a Database I’ll explain while filegroup level backups don’t fit the bill to solve this problem, and then talk through a couple of alternatives that may make life easier. In this post, we’ll talk through a sample problem. Over the years I’ve worked on a lot of backup and restore plans with SQL Server, and I learned the hard way that filegroup level restores don’t do exactly what you might think. The new filegroup is intended to help quickly restore data in cases when a monthly process goes off the rails and leaves the data in some tables in a bad state. The team mentioned they were planning to move some tables into a new filegroup. Please message the moderators and we'll pull it back in.This question came up when working with a client last week.
