The folder structure looks incorrect.
Did you copy folders by hand? Why?
The directory tree should look like this:
.
├── _deleted
│ ├── book
│ ├── file
│ ├── note
│ └── tag
├── data
│ ├── book
│ ├── file
│ ├── note
│ └── tag
└── state
But you have book, file, note, and tag in the root “data copy” folder.
What files does the data folder include? config.json should be also in the data folder.
You should take a backup again.
