Backups protect you from sudden loss, hardware failure, theft, or accidental deletion. Treat backups like an insurance policy: small regular steps reduce the risk of large, irreversible loss.
Decide what matters first. Prioritize documents, photos, and active projects so the backup process is focused and efficient.
Local backups use external drives or network storage for fast restores and offline control. They are useful when speed and privacy matter most.
Cloud backups store copies online and protect against physical risks to hardware. Combining local and cloud backups gives redundancy and lowers overall risk.
File History copies files in Documents, Pictures, Videos, and Desktop to an external or network drive. Turn it on in Control Panel under System and Security; select a drive and switch File History on to start automatic backups. Microsoft File History
File History keeps versions so you can restore earlier file states. Check the selected drive capacity and rotate drives if you prefer offsite storage.
OneDrive can back up Desktop, Documents, and Pictures and sync them across devices. Enable the Backup or Manage backup setting in the OneDrive app to keep those folders in the cloud. OneDrive folder backup
Using OneDrive adds easy remote access. Confirm which folders are synced to avoid surprises when files move from local folders to the cloud.
Time Machine is built into macOS and makes hourly and daily backups to an external disk. Connect a drive, open Time Machine settings, and select the drive to begin automatic backups. Apple Time Machine
Time Machine preserves hourly, daily, and weekly versions so you can restore individual files or the whole system. Use a drive at least twice the size of your Mac's storage for a comfortable retention window.
If you share a drive between Windows and Mac, format it in exFAT for broad compatibility. exFAT supports large files and is readable and writable by modern Windows and macOS systems. exFAT compatibility guidance
Note that APFS is best for Time Machine on modern Macs but not compatible with Windows. Pick exFAT for cross-platform file transfers and a Mac-native format for dedicated Time Machine disks.
Schedule daily or weekly checks to confirm backups complete and the drive is connected when needed. A backup that never runs is not protection.
Periodically restore a file or folder to verify backups are usable. Testing reduces unpleasant surprises if you ever need a full restore.
Enable versioning when available so you can recover earlier edits. For sensitive data, use encryption at rest or built-in options such as Time Machine encryption or cloud provider encryption settings.
Decide how long to keep old versions. Keep recent versions more frequently and delete very old ones to manage storage costs and space.
Pick a primary and a secondary backup method (local + cloud recommended).
Use an external drive formatted for your needs and keep one copy offsite or in the cloud.
Automate backups, then spot-test restores monthly.
Enable encryption for sensitive files and monitor backup storage use.
Follow official support pages for step-by-step setup and troubleshooting for your specific OS and cloud provider. Official guides explain current menus and options for reliable setup.
