After creating a new function using vs code and after deploying to the same function app all the other existing functions in that function app got removed(possibly the new function overwrite all the older 1s.Is there any solution to recover the existing functions of that function app.

That's the expected behavior. More at https://learn.microsoft.com/en-us/answers/questions/818136/does-publishing-one-function-app-wipe-out-the-func

You'd need to deploy all functions together.

For the recovery options, refer to https://github.com/MicrosoftDocs/azure-docs/issues/18258

Azure Functions creates an Azure File Share to store the functions. So, you can configure backups or create snapshots manually for this file share to keep track of changes being made but nothing is done by default. Without either of these enabled, I don't believe there is any way to recover the deleted files.

I mean i will check the file share and if i am able to resolve this. On the top of that when we deploy functions to function apps i believe the deployment files are stored somewhere so this function app was created on April, if somehow i can fetch those deployment files which were created for the first time when the function app was deployed and redeploy it does that work?Can i get the original version of the function app? Can this be a solution and if so how do i get the deployment files and redeploy

You'd need to locate the files used for the original deployment. Presumably you are using source code repo of some sort.

Hi Marcin,

Do you know where to look for the deployment files in azure , so the function app I am talking about in our project has been modified by several at different points in time, i know in our local machine the deployment package files are saved somewhere but in my machine it would be the most recent package which probably created the issue and represents the current state of this function app. However if it is possible the fetch the deployment files before that change happened, my instinct tells me somewhere in azure container linked with this function app might have all the deployment files for all the deployments we had till now for this function app. Please advise!

Hi Anindita,

it appears that you misunderstood my response. I'm referring to your own source code repository - presumably you have one. If not, then I'm afraid there is no option to locate the previous versions of Azure functions that were overwritten by a more recent deployment.
