Before any formatting, you must ensure the security of your personal information. A complete backup should include:
- Photos and videos.
- Contacts, agendas and calendars.
- Conversations on WhatsApp, Telegram, and other apps.
- Documents, downloads, music and miscellaneous files.
- Settings, apps, call history and SMS/MMS messages.
- Application-specific data.
There are multiple ways to back up your data, both online (in the cloud) and offline (on your computer or using specialized apps). Below, we cover all the methods to rigorously protect your data:
Automatic cloud backup with Google One, Google Drive, and Google Photos
Google offers a native integration for Android that simplifies this process:
- Opens Settings and access the section Google > make backup.
- Turn on the backup feature in Google One (or the equivalent service on your device).

- Put the mobile in mode File transfer.
- Copy the folders DCIM (camera), Download, Music, Documents, WhatsApp, Pictures and any other relevant ones on your PC.
- To restore, you'll just need to copy these files back to your phone.
This method is perfect if you don't want to rely on the cloud and want to back up data that isn't always covered by Google.
