Data backup is essential for protecting files from loss due to hardware failure, accidental deletion, cyberattacks, or disasters. Common backup options include:
- Local backups (external hard drives, USB drives): Fast and convenient but vulnerable to physical damage.
- Cloud backups (Google Drive, OneDrive, iCloud): Accessible anywhere and safe from local disasters but require internet access.
- Backup types:
- Full backup – copies everything
- Incremental backup – copies only changes since the last backup
- Differential backup – copies change since the last full backup
- Real‑time backup – saves changes instantly
- Best practice: Use a hybrid backup strategy combining local and cloud backups for maximum protection.
