Islamabad: (RightNow) WhatsApp backup allows users to secure their chats, photos, videos, and documents. Without a backup, data may be lost if the phone is damaged or replaced.

Through WhatsApp backup, Android users can save their chats to Google Account, while iPhone users can use iCloud. The backup time depends on data size and internet speed.

WhatsApp advises using Wi-Fi during backup, especially for large volumes of photos and videos. Larger backups may take more time to complete.

After backup, use the same phone number and account to restore old chats on a new phone. Transfer options are available, such as Android to Android or iPhone to iPhone.

Remember, WhatsApp also offers end-to-end encrypted backup. Losing the password or encryption key can make access difficult, so keep it in a safe place.
