Are you sure, that the downloaded file is ~45GB 🤔

Please try the `backup_full` service, since `snapshot_full` is depreciated

direct downloaded via supervisor UI (_created by `backup_full` service_) : size compared between supervisor and windows and 7zip ✔️ 

could you please share the corresponding logs from supervisor for both backup jobs?

please restart HA in safe mode and check if the messages still occur

mhhh ... ok, than please provide the [home-assistant.log](https://www.home-assistant.io/integrations/logger#viewing-logs) so we can see what's going on before these error message

there were many performance improvements done in 2024.3 and further are coming with 2024.4 ... please check if the issue still exists with current 2024.3

ok, so let's wait for 2024.4 (_will be released today evening_) and check again

> `config/custom_components/custom_templates/__init__.py` This is a custom component, which is not maintained by the HA core project. Please report your issue to the maintainer or in the source repository of this...

at all, please update to 2024.2.1 (_as soon as it is available_) - it will log error messages about the malformed strings, so we can fix them later
