问题 Is there any way I can do Azure Table Storage backup in to Azure Blob incremental way. AZcopy has solution for full backup for the table but not incremental. Is there any way I can recover Azure storage table, If I delete it from Azure storage explorer? 回答1: As far as I know, currently azure doesn't support auto backup the table data into blob. We need write codes to achieve this requirement. I suggest you could use azure webjobs/function or azcopy(as you says) to achieve this. If you want to

问题 I want to read an image from Azure blob storage by using opencv 3 in Python 2.7. How to do this without downloading the blob to a local file? 回答1: Per my experience, you can try to use get_blob_to_bytes method to download the blob as a byte array and covert it to a opencv image, as my sample code below. from azure.storage.blob import BlockBlobService account_name = '<your-storage-account>' account_key = '<your accout key>' block_blob_service = BlockBlobService(account_name, account_key)

问题 I have succesfully set up a static website on Azure Blob storage using the $web container as advised within the Microsoft documentation. In addition, I have defined index.html for both the 'Index Document Name' and the 'Error Document Name'. This is because I want my JavaScript application to handle the 404 responses.
