Thanks! Really looking forward to backing up my devops code with your app.

Hi @tysonsearls,
Thanks for the report :)
Just to confirm a few things, have you installed the tool via the provided installer, and what Windows OS are you running?
Looking forward to your reply.
Thanks.

[tysonsearls]

Yes, via the installer the msi file and windows server 2016

Update: I was able to get it to work/run by github cloning the older version to VS 1.0.5.8 and doing a nuget update to Newtonsoft.json and RestSharp to the newest versions. I am running the exe from the build bin folder without the installer. It looks like RestSharp was looking to the older version of Newtonsoft.json

[michaelmsonne]

Thanks for that! - I will look into it, what have been made and in the installer - looks like some mismatch 🫣

Hey, this is a side question. What good are the zip files? if you open them up it doesn't contain the code folder structure but guid files that have random characters. How do you restore the zip files to the code folder structure?

[michaelmsonne]

Hi @tysonsearls,

Good question :)

The RAW data from the Azure DevOps API is the .zip files containing the guid/metadata from it.
The content is in the files, but the filenames is not the correct ones no (don´t ask me why..).

To get the files name and the correct content, you will need to set the --unzip argument - it will unsip it and mark the guid/metadata together to the files.

[tysonsearls]

Ok, We have a lot of projects with many branches, so unzipped the disk could get full very fast, I was wanting to have your tool download them as a zip and unzip them manually when needed for disaster preparedness. Do you know of a way to do that? to have your tool download them as a zip then unzip them to something I can use? if not what is the point of downloading them zipped?

[michaelmsonne]

At the moment the tool can´t that ( unzip them manually when needed for disaster preparedness).

There is the --unzip argument to unzip the files when it got it from the API (.zip files, Microsoft decision as that the raw data retuned form the API), and then set the --cleanup argument to cleanup the .zip files when downloaded and unzipped.

I see the bug in the new installer - strange, as it was tested..

I see the code refer to some v. of assembly not here.

But I have now tested it, and I can fine run the files compiled in the bin folder - but not if installing it via the installer.
It´s something with the installer as I see it.

Looking into it.

[michaelmsonne]

Tested it - the file "AzureDevOpsBackup.exe.config" is missing in the installer.

I will fix.

[michaelmsonne]

Hi @tysonsearls ,

Fixed installer and some small other changes.

Get it here: https://github.com/michaelmsonne/AzureDevOpsBackupTool/releases/tag/1.0.6.0

Will look into a small tool aside to match the guid data to files for restore repos on-demand.

Will update you.

Thanks for the feedback! :)

EDIT: Fixed wrong link

[tysonsearls]

Thanks for you help Michael!

[michaelmsonne]

Allways @tysonsearls - sitting right now in Visual Studio and are in the makeing of a "AzureDevOpsBackupUnzipTool.exe" :)

[michaelmsonne]

Hi @tysonsearls ,

For a tool to unzip single repos based on .zip content and .json metadata - take a look here in development: https://github.com/michaelmsonne/AzureDevOpsBackupTool/tree/Add-toolToUnzipSingleBackup :)

[tysonsearls]

Thanks Michael!

[michaelmsonne]

I will close this one as the bug is fixed with a new installer (missing .config file).

I will update the rest when it´s tested and a new v. is out :)
