 # Record and replay live ASP.NET apps on Azure virtual machines using the Snapshot Debugger
 
-The Time Travel Debugging (TTD) preview in Visual Studio Enterprise provides the ability to record a Web app running on a Azure Virtual Machine (VM) and then accurately reconstruct and replay the execution path. TTD integrates with our Snapshot Debugger offering and allows you to rewind and replay each line of code however many times you want, helping you isolate and identify problems that might only occur in production environments.

 ## Set a conditional snappoint
 
-If it is difficult to recreate a particular state in your app, consider whether the use of a conditional snappoint can help. Conditional snappoints help you avoid collecting a Time Travel recording until the app enters a desired state, such as when a variable has a particular value that you want to inspect. [You can set conditions using expressions, filters, or hit counts](../debugger/debug-live-azure-apps-troubleshooting.md).
