Knoxite is free, open-source software for file storage and backup on Windows, macOS, and Linux.
What Knoxite is
Knoxite is free, open-source software for file storage and backup on Windows, macOS, and Linux. It stores incremental snapshots that users can restore to a chosen location or verify for chunk integrity. A repository can use multiple storage backends in parallel, including local filesystems, Dropbox, Amazon S3, Azure, Backblaze, Nextcloud, SSH, WebDAV, and FTP. Knoxite deduplicates matching file chunks, reducing repeated storage of identical parts, and supports snapshot compression with flate, gzip, lzma, zlib, or zstd; compression is off by default. Repository data is encrypted with AES using a password supplied at initialization. When multiple backends are configured, users can set fault tolerance for backend failures. Snapshots can be mounted read-only, while read-write mounting is still work in progress. Installation requires cloning the source repository and building Knoxite with Go. The documentation warns that losing the repository password prevents access to data, and that providing it through a command-line flag or environment variable is unsafe. Knoxite is released under the AGPL-3.0 license.
Good
- Free, open-source software under AGPL-3.0.
- Uses multiple storage backends in parallel.
- Deduplicates data at chunk level.
- Supports AES encryption with a repository password.
- Can restore snapshots and verify chunk integrity.
Watch out
- Installation requires cloning the source and building with Go.

Who it suits
Knoxite suits users who want open-source file backup with incremental snapshots and a choice of storage backends. It requires comfort with cloning the source and building the software with Go.
Verdict
Knoxite offers incremental snapshots, encryption, deduplication, and a broad set of documented backends. Treat the repository password as essential and account for the build-based installation and read-only mounting limit.
