In their own words
Backblaze Computer Backup
Backblaze Computer Backup backs up computer files to cloud storage without storage limits or restrictions on file type or size. Native backup software is available for Mac and PC, and iOS and Android apps provide access to backed-up data. Files are encrypted before leaving the computer and remain encrypted in Backblaze data centers; users can choose an additional private encryption key. All accounts support two-factor verification through TOTP or SMS. Files can be restored through the web, mobile apps or a shipped hard drive, and individual backed-up files can be shared. The personal monthly option costs $9 per month for unlimited cloud backup for one computer. The yearly option is listed at $8.25 per month when paid annually, and the two-year option at $7.88 per month when paid bi-annually. A 15-day trial is available, but there is no free plan. Business features include multiple-user management and administrative controls, with deployment tools and SSO options for business and enterprise accounts.
Kopia
Kopia is an open-source backup and restore tool that creates encrypted snapshots of selected files and directories. Snapshots are incremental, and content deduplication stores duplicate file content only once in a repository. Policies can schedule snapshots, set exclusions, define retention, and apply compression. Recovery options include mounting a snapshot as a local disk, restoring an entire snapshot to a chosen location, or selecting individual files. Kopia encrypts data and filenames before they leave the machine, supporting AES-256 and ChaCha20. Storage can use Amazon S3 and compatible services, Azure Blob Storage, Backblaze B2, Google Cloud Storage, WebDAV, SFTP, local or network storage, and some Rclone providers; Rclone support is experimental. Reed-Solomon error correction and repository consistency checks address data integrity. CLI and GUI interfaces are available, with optional server mode and an API for managing multiple machines. KopiaUI provides a web application in server mode. The software is free, but storage must be provisioned and paid for separately.
