If your chats include lots of heavy images, make sure you have a stable and fast internet connection to ensure the smooth completion of backups. A slow connection can hinder the backup operation.
I'm using this backup option regularly and find it very stable and easy to use. So, grab your smartphone and follow this guide to ensure your chats on WhatsApp are securely saved on a cloud.
To configure automated backup, first of all, go to your WhatsApp Settings option. Here, click the Chats option as shown in the image below.
On the Chats setting screen, scroll down a bit and select the Chat backup option.
On the chat backup screen, select the End-to-end encrypted backup option and click the TURN ON button. Clicking this option activates the password option.
Click the CREATE PASSWORD button and complete the process. Thereafter, you'll be asked to create an encrypted backup.
After creating the password, you'll be asked to create an encrypted backup. Click the CREATE button to complete the process. Depending on the volume and size of your chats, it may take some time to complete this process.
Note: If you're ok with unencrypted backups, skip this backup encryption process—entirely.
Next, it's time to configure the backup frequency. To do that click the Back up to Google Drive option on the Chat backup settings screen.Feel free to choose the backup frequency as per your needs. You can also opt for the manual option where chats are only saved when you explicitly press the backup button.
The next step involves the selection of a Google Account where you want to backup all the chats.
This option enables you to either select from one of the existing Google accounts which are already in a logged-in state on your device or you can use the Add account option to log in to the new Google account where you want all the backups to be forwarded to.
And last but not least is the Back up over option. This option enables you to select the type of data signal on the mobile device you want to use for the backup operations.
The latter option is (shown above) is recommended unless your chat backups are bulky.
I'll also recommend keeping the Include videos disabled else your Google Drive storage will get full in no time. So, that's how you configure automated backups for WhatsApp chats on Google Drive.
