About Zerobyte

Zerobyte is a backup automation tool for self-hosters, built on top of Restic. It adds a web interface for scheduling, managing and monitoring encrypted backups of remote storage, so Restic's capabilities can be used without hand-writing scripts and cron jobs.

Backups are encrypted, compressed and kept according to retention policies, with flexible scheduling for automated jobs and fine-grained retention rules. Data can be backed up from several protocols, including NFS, SMB, WebDAV, SFTP and local directories. The README says the full documentation, with setup guides and configuration reference, is on zerobyte.app.

Zerobyte runs with Docker and Docker Compose using the provided compose file. It is licensed under AGPL-3.0 and still at version 0.x, so the authors warn of major changes between versions. They also advise against exposing it directly to the internet, recommending a localhost port mapping with a secure tunnel, and against pointing its data directory to a network share.
