Samsung phones offer several options for backing up your personal data. You can use Smart Switch to back up everything to a physical storage device, such as an external SSD or a USB flash drive, or rely on Google Drive or Samsung Cloud backup solutions. Now, Google is offering more control over what data actually gets backed up to its cloud storage.Google has started rolling out per-app controls (via 9To5Google) for cloud backups. On Galaxy phones, you can access the feature by going to Settings > Accounts and backup > Back up data (Google Drive) > Other device data. There, youâll find individual backup toggles for first-party, third-party, and system apps. You can enable or disable backups for any supported app or service on your Galaxy phone.
