Best Online Backup Tools 2026

Online backup is insurance: it protects your computer from ransomware, hardware failure, and accidental deletion by continuously uploading files to secure servers. Backblaze offers unlimited backup for a flat $99/year, while IDrive combines backup with broader cloud storage and snapshot history across multiple devices. Your choice depends on whether you need unlimited coverage or multi-device flexibility.
