Clumoove

Clumoove is a high-performance, self-hosted open-source platform designed for lossless data migration, scheduled synchronization, and point-in-time snapshot backups across cloud providers, NAS systems, and servers.

Running entirely on your own infrastructure via Docker Compose, Clumoove streams data directly in memory between endpoints with zero intermediate disk caching, ensuring maximum privacy and data ownership.
