If you have changed your mobile phone or have you suffered any damage to your WhatsApp account that is not solved with an update of it, you may have to install the instant messaging application again or uninstall and erase completely the application, and reinstall it.
But you must bear in mind that, by doing so, you will lose all the conversations, files, audios and photos that you have in all your WhatsApp chats. So that this does not happen, you must make a backup copy of your WhatsApp – here we explain all the steps to do so, whether you have Android or if you have iOS – and, later, reinstall it in the new or the old terminal.
For recover and install a backup of your WhatsApp, the first thing you have to do is know where the copies are stored What you do.
If you have saved the copy in Google Drive, all you have to do is enter the Drive and touch on the ‘Backup’ menu option. There you can see all the copies made and you only have to touch on the one you want to manage. There you can also see the last ‘backup’ of the messaging ‘app’, but you cannot open or access the information, only restore it whenever you want. To do so, after installing WhatsApp, you open it, enter the phone number and click on ‘Restore’, which takes the copy stored in Google Drive. When the process is finished, you click ‘Next’ and your conversations are automatically displayed in the application. Afterwards, WhatsApp restores the media files.
If you want to use the backup stored the phone or the SD card to restore the chats, you need to transfer those files to the new device through a PC: you transfer them from the source mobile to a PC and then to the destination device or save the copy stored in the mobile to a card and you use that same card in the new terminal.
In this case, it is important to know that the phone stores the backups of the last seven days and that the local backups are performed daily at 2 in the morning. They are saved as a file on our phone. If the chats are not in the folder sdcard/Whatsapp/Databases, they may be in the ‘Internal Storage’ or ‘Main Storage’ folders.
There are cases when a backup cannot be recovered. That happens when, for example, the mobile is damaged without having saved a copy. But it can also happen to you if you change operating system -de Android a iOS- Or, even if you use the same phone number, if you log in on your mobile with an account (email address) different from the one in which you stored the backup.
