| Encryption | The site says TLS is used to encrypt connections and authenticate servers and clients, while stored file data uses AES and metadata uses Blowfish. | Kopia encrypts backup data and filenames before they leave the machine, and supports AES-256 and ChaCha20. |
| Incremental backups | The client detects file changes, encrypts them, and sends only the changed portions to the server. | Snapshots are incremental, and content deduplication avoids storing duplicate file content more than once in a repository. |
| Platforms | The installation wiki lists packages for Debian, FreeBSD, Windows, Gentoo Linux, Arch Linux, and RPM-based systems, and source compilation instructions for Linux, Mac OS X, FreeBSD, and Windows. | windows,macos,linux |

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.
