VolSync is a Kubernetes operator for asynchronous data replication and backup of persistent volumes. It enables efficient synchronization between storage locations using rsync, restic, or Rclone, making it ideal for backups, disaster recovery, and data migration across clusters.

How It Works

VolSync automates snapshot-based or file-based replication of PVCs, supporting:

• Local backups (e.g., to another PVC or storage backend)
• Remote replication (e.g., across Kubernetes clusters)
• Incremental synchronization to optimize storage and bandwidth usage
