Google One is a cloud storage service provided by Google that offers various benefits, one of which is backup functionality. While Google One provides backup services for many aspects of your device, it is important to understand that it does not backup everything on your phone by default. Here are some key points to consider:
1. App data backup: Google One offers app data backup for select applications, but this feature is dependent on app developers enabling it. Not all apps are included, so it's essential to check which apps are supported in the Google One settings.
2. Device settings: Google One does not automatically back up all the settings on your phone. However, certain settings data, such as Wi-Fi network configurations and preferences, may be backed up if you have enabled the relevant options in your device's backup settings.
3. Photos and videos: By default, Google Photos (which is closely integrated with Google One) can automatically back up your photos and videos. However, starting from June 2021, high-quality backups consume your Google account storage space, whereas original quality backups count against your storage quota. Therefore, it's essential to configure the backup settings according to your preferences.
4. Contacts, calendar, and messages: Google One also offers backup capabilities for your contacts, calendar events, and messages. These items can be synced across multiple devices using your Google account.
To ensure a comprehensive backup of all the data on your phone, it's recommended to utilize a combination of Google One's backup services, as well as other backup solutions such as local device backups or third-party backup apps. This will provide you with a more complete and secure backup strategy.
