Please clear my problem on WhatsApp backup
A few days ago I asked for members' help for suggesting the optimum choice on the new phone I intended to buy. I have now bought the previous model phone going by the majority opinion members gave me in this thread.Now I need to transfer my WhatsApp to the new phone. My doubt is about the backup in this regard.
The suggestions and methods available in the net are really confusing me. I am afraid what will happen if I go wrong. So I seek help from experienced members and tech savvy members.
1. I tried the Google account back up(which I never did earlier). It asked for a Google account. I gave the google account I was using in the phone for installing apps etc. But when I put that and gave password it did not allow further saying it is already existing. But it was not detecting or showing that account in the chat backup page and displaying google account not selected. Helplessly, I was compelled to give my another Gmail account for the backup.(which I was using for my daily needs) taking long time it showed a back up of about 1,8 GB. I saw it is there in the storage of google drive of that Gmail account.
2, I also transferred the file 'msgstore.db.crypt14' to the new phone by Bluetooth. But it is just 201 MB.
Now my question is have I done the back up correct? Can I install and operate WhatsApp in my new phone with the Gmail account back up or with the megastore file?
Why it is not detecting or backing up to the original google account? How can I change the newly added google account in the chat back up selection?
After logging in in the new phone (phone number same) will there be any WhatsApp messages left in the old phone? Or will there be any chat history file there? If needed how to retrieve them?
Please give the answers and solutions for my problem.
