Restoring Azure App Service backup to different site - azure

Question

How can I use Restore-AzureRmWebAppBackup to restore an app service to a different existing site? This can usually be done in the portal, but for some reason the destination app service is not listed, even though it's in the same resource group.

Answer 1

How can I use Restore-AzureRmWebAppBackup to restore an app service to a different existing site?
Here is a sample code of restore web app from PowerShell.
$resourceGroupName = "target web app resource group name"
$appName = "target web app name"
$blobName = "backup blob name"
$storageAccountURL = "SAS URL of your blob container"
Restore-AzureRmWebAppBackup -ResourceGroupName $resourceGroupName -Name $appName -StorageAccountUrl $storageAccountURL -BlobName $blobName -Overwrite
We can find the blob name from the restore page after you backup your web app.

Answer 2

Following is the solution using Bash CLI:
prerequisite: A storage account with a container and the container URL for the same. The container URL contains the access the key (SAS). More information about the container URL can be found here: https://learn.microsoft.com/en-us/azure/storage/storage-dotnet-shared-access-signature-part-1
You can also use the following command to generate the SAS token:
az storage container generate-sas --name <container-name> --expiry <sas-expiry> --permissions <permissions> --account-name <account-name> --account-key <account-key>
To clone the app, use the following commands:
backupname=appname_`date "+%Y%m%d%H%M%S"`
az webapp config backup create --resource-group $OriginresourceGroupName --webapp-name $originAppName --backup-name $backupname --slot $OriginSlotName --container-url "$ContainerURL"
az webapp config backup restore --backup-name $backupname --container-url $ContainerURL --resource-group $TargetresourceGroupName --webapp-name $TargetAppname --overwrite --ignore-hostname-conflict

Use below cmdlets to restore last successful backup to slot or app
$resourceGroupName = "<<RG NAME>>"
$primarywebappname = "<<APP NAME>>"
$slotname = "<<SLOT NAME>>"
# Get the last Sucessfull BackupID of the backup you want to restore
$backupID=Get-AzWebAppBackupList -ResourceGroupName $resourceGroupName -Name `
$primarywebappname|where BackupStatus -EQ "Succeeded" |select -Last 1 |select BackupId
# Get the backup object that you want to restore by specifying the BackupID
$backup = (Get-AzWebAppBackupList -ResourceGroupName $resourceGroupName -Name
$primarywebappname | where {$PSItem.BackupId -eq $backupID.BackupId})
# Restore the app by overwriting it with the backup data in the slot
$backup |Restore-AzWebAppBackup -Slot $slotname -IgnoreConflictingHostNames -Overwrite
# Restore the app by overwriting into the exsisting App
$backup |Restore-AzWebAppBackup -Overwrite
