I've come across an issue with created folders not synchronising correctly in Azure Storage. When a folder is created in Azure Blob Storage it also creates a 0 byte file by the same name. This causes an issue when copying files to and from storage accounts as errors experienced state that there is already a file by that name.
I'm currently in contact with Microsoft, who are assisting with the folder/file structure but they think it could potentially be a bug with the Umbraco code, although I think they may be clutching at straws.
I am using third party applications such as Cloudberry Explorer and ClumsyLeaf Explorer to view Azure Blob Storage and can see these 0 byte files. Has anyone encountered this before? Would this be part of Umbraco Accelerator's code?
Please see the attached screenshot... Notice the 0 byte files on the left hand column are the same names as the folders.
I'm getting the exact same problem. We still haven't had a resolution to this despite escalating it to Microsoft themselves.
Have you had an answer? Are you using the Azure Accelerator for Umbraco (codeplex project)? How many roles you got on this deployment?
I suspected it might be because of the propagation between the web roles.
This was just confirmed in our case. Assuming you are indeed running the accelerator, check out approximately line 54 of WebRole.cs. You'll see a Run override method, like this:
public override void Run()
{
this.SyncForever(TimeSpan.FromSeconds(60));
}
Change the value. You'll notice the files only appear after that number of seconds. Comment it out, and you don't get them!
The code comes from the Uploader-app, which you use to upload a site to blob storage as part of the deployment process in the Windows Azure Accelerator for Umbraco.
This is excellent. It's done the job perfectly. I now have this running as a scheduled task on a backup server which allows us to have a 7 day cycle of website files.
I'm using your application as my backup script for my live site. Works so nice and simply that I hope you can release the source at some point - or develop into a configurable application (e.g. multiple sites, etc).
Umbraco on Azure - 0 byte files in Blob Storage

Hi,
I just added a comment to a similar discussion on codeplex - you can read my comment here:

Hi again,
I created a simple console app that'll download your websites from Azure Blob Storage and keep the correct file- and folder structure. Its available for download in the projects section: http://our.umbraco.org/projects/developer-tools/azure-website-downloader
Hope you find it usable.

Fantastic job.

Thank you Morten. This does the trick perfectly.
I'm using your application as my backup script for my live site. Works so nice and simply that I hope you can release the source at some point - or develop into a configurable application (e.g. multiple sites, etc).
Cheers again for your help!
Hi Chris,
Good to hear!
The source is actually available -> if you look under the 'Resource' there is a link to a bitbucket repository with the source:
