They're designed to work side by side, and using both is the safest choice. What Time Machine does Time Machine is built into macOS. It backs up your files, apps and settings to a backup disk. It keeps hourly backups for the past 24 hours, daily backups for the past month and weekly backups for older months, removing the oldest when the disk fills.
