Why bother with backup?

  • Article

Backing up SQL Server data is like many of the things we do because we figure we need to. It is good for you, like eating a good diet and getting exercise. Unfortunately, folks are often about as successful with SQL Server backups as they are with diet and exercise.

This is the first in a series of articles covering SQL Server database backup. The series starts from the very basics of why database backup is important. The question of why to backup a database can inform many other decisions.

Question of the Day

The Empty Aggregate

I have this table in a SQL Server 2025 database:

CREATE TABLE [dbo].[CustomerOrder]
(
[OrderID] [int] NULL,
[CustomerID] [int] NULL,
[total] [money] NULL
) ON [PRIMARY]
GO
What is returned from this code? (answers are for the sum and then the count)
SELECT SUM(total) AS sum,
       COUNT(total) AS count
FROM dbo.CustomerOrder;
