How reliable is Firestore as an autonomous stability mechanism?

Question

I am currently using Firebase Firestore as the main backend, which retrieves data from various sources. I also use the Android Room for my mobile backend. When the phone receives data, it is stored in the Room database if the user is not connected to the network again for several days or even weeks.

Having looked at the device files, I see that firestore saves data in files in a directory /data/data/<your-app>/databases.

The file looks something like this
