Говорит не архив это
VP
Я щас скачал все 30 файлов и не один не открылся
ДЦ

VP
А ре файлы которые вручную архивировал открылись

According to https://github.com/home-assistant/hassio/blob/dev/hassio/utils/tar.py
HomeAssistant’s snapshot is tar archive that consists of SecureTar archives.
SecureTar is a HomeAssistant abstraction.
It looks like normal tar.gz archive but it isn’t - that’s why you can’t just uncompress it.
First 16 bytes - is a salt
Then goes AES 128 CBC encrypted data. (the data is a tar.gz archive)
Key = your password.
IV calcultaed based on salt and key by following code:
Copy to clipboard
def _generate_iv(key: bytes, salt: bytes) -> bytes:
"""Generate an iv from data."""
temp_iv = key + salt
for _ in range(100):
temp_iv = hashlib.sha256(temp_iv).digest()
return temp_iv[:16]
I can’t decrypt it via command line tools because of too complex iv calculation function. Maybe we can just use python to decrypt it.

Написано выглядит как тар гз, но это не совсем так

А ты пароль на архив ставишь?
VP
И чем ты бэкап делаешь?
ДЦ
нет пароля
ДЦ
снапшоты стандартные
