Create chat backup in WhatsApp
WhatsApp allows saving your chat histories and media in iCloud – without third-party software. To create a chat backup, open WhatsApp
on your iPhone and tap the settings icon (cogwheel) at the bottom. Then go to Chats and on the next level to Chat Backup.
Create manual backup
Setting up the automatic backup for your WhatsApp chats is far more useful and convenient than the manual backup. Open the Chat Backup level again and click the option Automatic Backup.
