What Knoxite is
Knoxite is an open-source backup and storage system for protecting files across Windows, macOS, and Linux. It saves incremental snapshots, which users can restore to a chosen location or check for stored-chunk integrity. Repositories can use multiple backends at once, including local storage, Dropbox, Amazon S3, Azure File Storage, Backblaze, Google Cloud Storage, Mega, Nextcloud, ownCloud, FTP, SSH/SFTP, and WebDAV. Knoxite removes duplicate data at the chunk level, and snapshots can be compressed with flate, gzip, lzma, zlib, or zstd; compression is off by default. Repository data is encrypted with AES using a password set 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 remains in progress. Knoxite is free under the AGPL-3.0 license. Installation requires cloning its source repository and building it with Go.
Who it suits
Knoxite suits people who want file backups with control over storage backends, encryption, and snapshot handling. It is aimed at users comfortable building software with Go and managing a repository password.
What it does well
- Free, open-source software under AGPL-3.0.
- Supports multiple storage backends in parallel.
- Chunk-level deduplication avoids storing matching file parts twice.
- Can restore snapshots and verify chunk integrity.
- Supports AES encryption and configurable backend fault tolerance.
What to know first
- Installation requires cloning the source and building with Go.
- Losing the repository password prevents data access.
- Read-write snapshot mounting is still in progress.
- WebDAV has only been tested with Nextcloud and ownCloud.
Limits
Its documented mounting mode is read-only, and read-write mounting remains in progress; losing the repository password prevents access to the data.

Verdict
Knoxite offers broad backend choice, encrypted incremental snapshots, and file restoration without a software fee. Its build-from-source installation and password-loss risk are important considerations for managing it.
Questions
Is Knoxite free?
Yes. Knoxite is free, open-source software under the AGPL-3.0 license.
Which platforms does Knoxite support?
It supports Windows, macOS, and Linux, and is also listed for self-hosted setups.
What can I back up and restore?
Knoxite backs up files into incremental snapshots and can restore them to a chosen location.
Which storage backends can I use?
Documented backends include filesystem storage, Amazon S3, Azure File Storage, Backblaze, Dropbox, Google Cloud Storage, Mega, Nextcloud, ownCloud, SSH/SFTP, FTP, and WebDAV.
