xreplicator

This is the distribution and release repository for the xreplicator tool. Also if you want any community support, please use the Discussions section of this repository. For any commercial support, please contact vishnu@xmigrate.cloud.

Product Overview

xreplicator is a production-grade block-level incremental backup system with eBPF change tracking for dramatically faster incrementals. It is designed for backup, restore, and disaster recovery using innovative incremental backup techniques, with a goal of zero data loss.

Key Capabilities

• eBPF-accelerated incrementals that track only changed blocks at the kernel level
• Automatic scheduling for full and incremental backups
• Deduplication and compression to reduce storage
• Recovery mode for crash/power-loss scenarios
• Multi-filesystem support (ext4 and XFS)
• Production-ready operations (systemd integration, monitoring, graceful shutdown)

Licensing And Support

• Always free for up to 5 VMs.
• 1 year free for companies impacted by geopolitical instability.
• Use Discussions in this project to get support for any issue you face.
• For a community license or war license, contact vishnu@xmigrate.cloud.

Kubernetes Distribution

The backup server can run in Kubernetes. The Helm chart defaults to bundled PostgreSQL and MinIO for a self-contained install. Customers can disable those components and point the chart at external PostgreSQL and S3-compatible object storage.

Distribution artifacts:

• Runtime image packaging: container/backup-server, container/frontend
• Raw Kubernetes manifests: deploy/kubernetes
• Docker Compose quickstart: deploy/docker-compose
• Helm chart: charts/xreplicator-backup-server
• GitHub Actions workflows:
  • Backup server image: .github/workflows/backup-server-image.yaml
  • Frontend image: .github/workflows/frontend-image.yaml
  • Helm chart package: .github/workflows/helm-chart.yaml

Image:

ghcr.io/xmigrate/xreplicator-backup-server:<version>
ghcr.io/xmigrate/xreplicator-frontend:<version>

Helm chart:

ghcr.io/xmigrate/charts/xreplicator-backup-server:<version>

Published releases also include the packaged chart:

xreplicator-backup-server-<version>.tgz

Install the published Helm chart:

export VERSION=1.4.3

helm upgrade --install xreplicator \
  oci://ghcr.io/xmigrate/charts/xreplicator-backup-server \
  --version "$VERSION" \
  --namespace xreplicator \
  --create-namespace \
  --set fullnameOverride=xreplicator \
  --set image.tag="$VERSION" \
  --set frontend.image.tag="$VERSION"

For a single-host trial, use Docker Compose:

cd deploy/docker-compose
cp .env.example .env
docker compose up -d

Active-active Kubernetes deployments use a StatefulSet so each replica has a stable identity and peer-reachable DNS name. Single-replica Kubernetes deployments are supported by setting replicaCount: 1 and server.activeActive: false in the Helm values.
