Vinchin: Real-Time Replication for Zero RPO & Business Continuity

Vinchin supports system-level and disk-level real-time backups, ensuring comprehensive data coverage and rapid recovery. When a production host experiences data loss, it enables fast rollback from the backup system to the exact point before the loss to recover valuable data. Disk data on production hosts is synchronized in real time to the standby system, and host heartbeat/online status is monitored continuously; in the event of sudden failures such as a host crash, services can be automatically failed over to the standby without performing a recovery operation, more effectively guaranteeing RTO ≈ 0 and RPO ≈ 0.

Why Choose Vinchin for Real-time Replication?

Vinchin Backup & Recovery delivers reliable protection for enterprise data

Real-time I/O Monitoring & Capture

Disk-level real-time backups with second-level I/O capture and real-time data synchronization to ensure near-zero data loss, achieving RPO ≈ 0.

Full-system Failover, RTO ≈ 0

Supports primary-secondary replication and automatically detects applications such as databases, allowing automatic takeover of the entire system and its applications in the event of a failure.

Ensure Application Consistency

Using a tagged-point strategy, application data is flushed at regular intervals to guarantee timely writes to disk, thereby ensuring application consistency.

One-click Failback

After the disaster-recovery site takes over services, temporary data is retained until a failback is initiated, ensuring seamless restoration of data back to the source environment.

Highlight Features of Vinchin Real-time Replication

Continuous Data Protection

Continuously synchronize disk I/O changes in real time to provide uninterrupted protection, ensure data consistency, and meet real-time data protection requirements across all scenarios.

Resumable Data Transfer

After a production host recovers from events like system reboot or network interruption, incremental synchronization can resume without retransmitting all data. This effectively avoids data-security risks from unexpected task interruptions and reduces duplicate transfers.

Point-in-Time Rollback

Continuously capture production I/O and sync it to the backup system so that, in the event of logical errors or operator mistakes, you can roll back to any point in time.

Online Data Migration

Support migration with broad data compatibility. The production host remains online throughout the migration to ensure business continuity, and all data is transmitted with encryption during the transfer to guarantee security.

Integrated Validation Environment

Built-in validation platform lets you pick any backup point for verification or drills without having to provision extra systems, storage, or network environments.

Primary–Standby Real-time Sync

Production host data is synchronized in real time to the standby host, and the standby host does not require pre-installed OS, applications, or other environments.

Typical Application Scenarios

Remote Disaster Recovery (DR / Hot Standby)

Replicate the entire production system in real time to an offsite backup center so that if the primary site fails or the data center becomes unavailable, services can be switched instantly to the backup. Ideal for mission-critical workloads that require near-zero RPO and very low RTO, such as banks, e-commerce, and hospitals.

Zero-downtime Maintenance & Data Center Migration

During hardware replacement, facility maintenance, or full-site migration, real-time replication keeps the source system online and unaffected. After validation, you switch to the target system with virtually no interruption for end users. Commonly used for large websites, enterprise applications, and environments that require out-of-window maintenance.

Cross-Data-Center Load Balancing and Fast Failover

Replicate entire systems to a secondary data center for read/write separation, rapid takeover during traffic spikes, or automatic failover when the primary node fails—improving availability and business continuity. Suitable for high-concurrency services, real-time analytics platforms, and critical databases (e.g., online transactions, real-time monitoring).

Key Benefits with Vinchin Backup & Recovery

Comprehensive protection for your Linux data, empowering you to overcome any challenge

Very Short Recovery Time & Fast Failover

When the primary becomes unavailable, the standby can take over almost immediately, significantly shortening RTO. Compared with traditional restore-from-backup methods, real-time replication minimizes revenue loss and customer churn caused by downtime and ensures core services remain available.

Near-zero Data Loss (RPO ≈ 0)

Full-system real-time replication synchronizes data to the standby as it is written on the primary. Even in the event of an unexpected crash, hardware failure, or disaster, data remains highly consistent. For finance, healthcare, e-commerce and other scenarios that demand strict transaction and record integrity, this means business won’t suffer major losses due to missing data.

Zero-downtime Maintenance and Smooth Migration

When upgrading hardware, migrating a data center, or performing system maintenance, real-time replication keeps the source and target continuously synchronized. Users will barely feel any interruption at switchover, and operations teams can perform work more safely and flexibly, reducing the risks and costs associated with downtime.

Improves Availability and Compliance Capability

With real-time replication, organizations can easily implement dual-data-center hot standby, run regular drills, and meet disaster-recovery compliance requirements. This not only helps ensure critical systems run continuously, but also provides reliable DR evidence for audits—boosting customer trust and competitive standing.

Supported Workloads

Frequently Asked Questions

Does the standby host require pre-installed OS and applications?

No. The standby receives system and application data directly from the primary, so it can take over immediately without prior setup, simplifying deployment and reducing switchover time.

Can it handle interruptions like reboots or network failures?

Yes. After the production host recovers, incremental synchronization resumes automatically without retransmitting all data, reducing duplicate transfers and preventing data risks.

How does Vinchin minimize data loss during unexpected failures?

It captures disk I/O at the second level and synchronizes data in real time, ensuring near-zero data loss even in sudden crashes or disasters.

Can real-time replication be used for disaster recovery across data centers?

Yes. If the primary site fails, services switch instantly to the secondary site, ensuring business continuity.
