Don't catch all exceptions. Always limit it to errors you expect it to be raised

[mkohns]

HI Paulus! Thank you for reviewing and taking your time. I am new in homeassistant and perhaps would need a little more help. But I am eager to learn. This is the list of exceptions botocore could raise:
https://boto3.amazonaws.com/v1/documentation/api/latest/guide/error-handling.html#botocore-exceptions
I can not see in the documentation of session.client which exceptions it could raise. I browsed through the code and I think that could be a lot. Many should be covered by ClientError. But how should I take care for the Exceptions I am not aware of? I thought the "final" exception is taking care for this. If I would remove it - and an uncatched exceptions is being raised - what happens then? What is your recommendation?

Did you think about using one of the asyncio implementations (aiobotocore/aioboto3)? This can make your code significantly shorter (check my azure_storage PR for a comparison)

Hi, yes i tried to use the async libs, but did not succeed. My skills have not been high enough to get this sorted out :(
I looked into your code at https://github.com/zweckj/home-assistant-core/blob/azure-storage/init/homeassistant/components/azure_storage/backup.py - but do not understand how to transfer the azure.core code to aioboto. Is it a problem to leave it as is?
