Copying large SQLite databases can be inefficient due to the presence of indexes, which increase file size and transfer time. By using SQLite's .dump command to create a compressed text file of the database, users can significantly reduce the size for faster transfers while ensuring data consistency during the copying process. This method has proven to save time and improve reliability when handling large databases.
