Nói chung khi tôi bắt đầu trong một môi trường mới, tôi có xu hướng kiểm tra các bản sao lưu ở đâu, khi toàn bộ lần cuối được thực hiện, khi nào khôi phục lần cuối được áp dụng và tôi cũng kiểm tra bảo mật.
Cách tôi làm điều này là thông qua T-SQL.
Kiểm tra các bản sao lưu

Câu hỏi:
Ngoài những điều trên, có những điều khác tôi nên kiểm tra khi bắt đầu vào một môi trường mới như là một vấn đề ưu tiên?
