database-backups

I have scheduled backups running through SQL Agent, with Full Backups nightly, and differential backups hourly. Is there a way to determine which of the backup files is the Full backup, and which is the latest differential?

Intuitively, it would seem the largest backup within 24 hours is the full, and the latest smaller backup is the partial. However, this isn't robust.

Is there a way to probe the backup file to check the backup type? (Preferably in c#)

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
