XReplicatorContinuous Backup Engine

Server backup & disaster recovery.Restore and migrate with confidence.

XReplicator captures changed blocks from Windows and Linux agents, stores them in a centralized backup server, and lets you restore files, partitions, or full disks on demand.

What It Does

Backup, restore, and migrate server workloads

XReplicator is a server backup and disaster recovery platform built for Windows and Linux environments with always-on workloads.

1

Protect Windows and Linux servers with block-level incremental snapshots.

2

Verify restore points before recovery with metadata, sample, or full checks.

3

Restore files, partitions, full disks, or Azure DR workloads from centralized backups.

Change-Scaled Runtime

Change-block tracking means only modified data is transferred, so runtime tracks change volume instead of total disk size.

Security Assurance

Security built for ransomware-resilient backups

XReplicator protects backup communication, makes stored restore points harder to tamper with, and gives operators evidence that backups can be restored.

1

Secure transport

TLS and optional mTLS protect agent, backup server, and dashboard gRPC traffic.

2

Immutable backup copies

Retention windows and S3, Azure Blob, or GCS object-lock support help prevent backup tampering.

3

Verifiable restores

Metadata, sample, and full verification modes confirm restore points before recovery is needed.

4

Ransomware signals

Block churn anomaly alerts, audit logs, and last-known-clean suggestions help during recovery.

How It Works

Built for fast backups, clean restores, and ransomware resilience

A simple workflow that scales from a handful of servers to large fleets without changing your operational model — with transport security, immutable backup copies, and restore verification built in.

Step 1
Track Changed Blocks

Capture only block-level changes from source devices in real time.

Step 2
Dedup + Compress

Reduce storage footprint before writing to local or cloud object storage.

Step 3
Restore By Scope

Recover files, partitions, or full devices from any snapshot in the chain.

Step 4
Verify Recovery

Run metadata, sample, or full restore verification so operators know which restore points are usable.

Compared to Snapshot Tools

Backups live on the backup server, not on each host. That means you can restore or migrate to any server later, with long-term retention built in.

Server Backup & Disaster Recovery Use Cases

How organizations use XReplicator to protect their data

Scheduled Backups

Set hourly, daily, or weekly. XReplicator handles the rest.

Automatic scheduling with systemd integration. Full backups on your schedule, incrementals in between. Never miss a backup.

to navigate
Built for Performance

Performance That Matters

Faster backups. Smaller footprint. Change-aware recovery time.

Performance and restore time vary with change volume, infrastructure, and selected restore scope.

100× Faster

Incremental Backups at Speed

Only changed blocks are captured — not full snapshots. Backup duration scales with how much changed, so small incrementals finish quickly while larger changes take longer.

Better Storage Savings

Encrypted & Compacted

AES-256 encryption with built-in deduplication and compression improves storage efficiency across local and cloud object storage, while keeping backups secure.

Sub-40s Azure DR

Measured Failover RTO

Measured Azure-to-Azure failover completed in under 40 seconds with attach-as-is disks and around 70 seconds from snapshots for a 30 GB OS disk plus 4 GB data disk.

FAQ

Backup, restore, and migration questions

Quick answers for teams evaluating a server backup, restore, or disaster recovery tool.

What server workloads does XReplicator support?

Windows (NTFS) and Linux servers (ext4/XFS). Agents run on client machines and send block-level changes to the backup server.

Can I restore an entire server or only files?

You can restore files, partitions, or full disks. Point-in-time recovery works for disaster recovery and migration use cases.

How is this different from filesystem snapshots?

XReplicator tracks changed blocks and stores them centrally, so you can restore to new hosts and keep long-term retention without tying backups to a single server.

Does it support cloud backup?

Yes. The backup server can sync snapshots to S3-compatible storage, Azure Blob, and Google Cloud Storage for off-site retention. Immutable object storage can be used for ransomware-resilient copies.

How does XReplicator secure backup data?

XReplicator supports TLS/mTLS for agent, server, and dashboard communication, immutable retention windows, object-lock storage, checksum verification, and audit logging.

Can XReplicator help after a ransomware event?

Yes. It can detect unusual block churn, suggest the last-known-clean restore point, protect off-site copies with object-lock storage, and verify backups using metadata, sample, or full restore checks.

Are restore points immutable?

XReplicator supports an immutable retention window on the backup server and object-lock style immutability for S3-compatible storage, Azure Blob, and Google Cloud Storage targets.

What is the difference between metadata, sample, and full verification?

Metadata verification checks that the snapshot manifest is readable, sample verification checks selected chunks from the resolved restore chain, and full verification reads and checksum-validates all logical chunks.

Can XReplicator set up Azure-to-Azure disaster recovery?

Yes. XReplicator v1.3.1 supports Azure-to-Azure DR setup with orchestrated failover and failback from the web UI. In measured drills on a VM with a 30 GB OS disk and 4 GB data disk, failover completed in under 40 seconds with attach-as-is disks and around 70 seconds when creating from snapshots, once staging disks were healthy and synced.

Is MSP multi-tenancy included in the free Community Edition?

No. Community Edition is the single-tenant free version for up to 5 VMs for life. MSP multi-tenancy, user management, and tenant isolation are gated Enterprise features.
