You've got a couple of choices. You can either a.) Hookup to the Umbraco events (on publish, on save, on delete, etc.), or b.) create a /base rest extension that will allow you to call your method by going to http://yourdomain.com/base/yourAlias/yourMethod/.

Using subscribing to Umbraco's events may not be what you'd need, especially if you want to run your maintenance at a specific time each day. But here's a few links showing what events are available and how you'd go about using them:

Event Examples

Umbraco base would be the best choice if you are wanting to schedule your maintenance to run at specific times. After you build a base class you can set it to run at intervals using Umbraco's scheduled tasks. There's event a nice package that allows you to manage the scheduled tasks, called TaskScheduler. Here are some links:

Hi,

Not to plug CMSImport too much but it's exactly what you are after:

• Import documents from a different location based on various datasources.
• Update documents
• Schedule import definitions

Only downside is that the update and schedule feature isn't included into the free edition. You might want to check out the free edition and video's on http://cmsimport.com/

Hope this helps you,

Richard

It seems as if /Base is exactly what I'm searching for - it doesn't appear in the backend. I'll test this solution later and let you know, if it worked.

Thanks a lot for your answers.

I tried to apply the base sample and used the following code:

[RestExtension( "MatyMaintenance" )]
public class MaintenanceClass
{
   [RestExtensionMethod()]
   public static string UpdateDocuments()
    {
     // Updating the documents
 }
}

I wanted to start the code with showing the page in the browser: 

http://localhost:33621/MatyMaintenance/UpdateDocuments

But it shows me a 404. Do I need to install or configure something?  The article about /Base says, that umbraco finds the extension automatically, if it is marked with the custom attributes.

Thanks in advance

You'll need to add /base to the url:

http://localhost:33621/base/MatyMaintenance/UpdateDocuments

Also, if you get permission errors you may want to add allowAll=true to the RestExtensionMethod annotation:

[RestExtension( "MatyMaintenance" )]
public class MaintenanceClass
{
    [RestExtensionMethod(allowAll=true)]
    public static string UpdateDocuments()
    {
        // Updating the documents
    }
}

Thanks a lot! The /base in the url did the trick.

If you ever come to Freising, you'll get some beer... ;-)
