I thought DCL operations were unrelated to backups.

Nah, that shouldn't matter, backups can run while the instance is active.

Wait, can backups fail just because the instance isn't stopped?

I feel like DCL operations are less likely to affect backups, but I can't recall the specifics. Maybe option D is a distraction?

I practiced a similar question, and I think stopping the database instance might not be necessary for backups, so I doubt option A is correct.

I'm not entirely sure, but I think DML operations could also interfere with the backup process. Could it be option C?

I remember reading that DDL operations can cause issues during backups, so maybe option B is the right answer?

Okay, I think I've got this. The goal of an incident response plan is to contain an attack and prevent it from spreading, right? That sounds like the most logical answer based on what I've learned.

Pass-through seems most logical - it implies actual transactions happening, but primarily as a mechanism to disguise something else.

Okay, let's see. The key here is understanding how Alibaba Cloud ECS instances are charged when they are stopped. I think I can figure this out.
