A cloud backup solution that employs the "ChaCha20 + Serpent-256 CBC + HMAC-SHA3-512" authenticated encryption scheme for data encryption and ML-KEM-1024 for quantum-resistant key exchange. Check it out at https://plum-cave.netlify.app/ GitHub page: https://github.com/Northstrix/plum-cave

Private, secure backups in the cloud of any size with minimal resource usage exactly the way you want them. Your data is encrypted by default using encryption keys only available to you and before leaving your network. Backed up data is signed to ensure protection from tampering. Data can be stored with any amount of redundancy and even multiple backup locations simultaneously. No information about the contents of your data is saved in any backup location. Only you can download and access your data. The services has been designed from the ground up to preserve the privacy and integrity of customers and their backed up data, you are not our product!

ZeroByte is a self-hosted backup automation platform built around the robust Restic backup engine, delivering encrypted, compressed, and schedulable data protection with a modern web interface. It targets self-hosting enthusiasts, homelab operators, and small teams who need a straightforward way to manage backups across diverse storage backends without resorting to complex scripts or CLI-only tools. Zerobyte lets you configure automated jobs with flexible schedules and retention policies, monitor backup jobs through a centralized dashboard, and choose from multiple source types (like local directories, NFS, SMB, WebDAV, and more), all while ensuring end-to-end encryption via Restic underneath. The system also supports common remote destinations such as S3-compatible storage or REST servers and encapsulates much of the complexity of backup logic so users can focus on reliability and restore confidence rather than manual orchestration.
