Local Replication
The intelligent data protection enables
any point-in-time recovery
In business-critical environments, users require frequent protection for their valuable data sets. To help users protect data in the most efficient way, Infortrend Local Replication leverages the power of Infortrend EonStor DS storage systems to provide snapshot and volume copy/mirror capabilities. With space-saving snapshot copies, users can easily restore files or rollback data as necessary. With the full data copies, users can quickly recover service when a RAID-protected volume fatally fails.

Local Replication - Snapshot
With the traditional way of tape and full copy backups, frequent data backup is not practicable since it will cause excess space consumption and performance degradation. To facilitate more efficient data protection, Infortrend Local Replication allows users to perform instant, low-impact backups with the snapshot capability. Snapshot images are space-efficient differential copies. At the instant of snapshot creation, a point-in-time data image is taken without disrupting online applications. Based on the image, data changes will be copied to the snapshot volume when new writes occur. With copy-on-write design, the snapshot capability of Infortrend Local Replication protects production data from accidental modifications, deletions and corruptions with minimal capacity requirements and performance overhead. By accessing a snapshot copy as the desired recovery point, users can immediately restore system availability from data disruption.
Local Replication - Volume Copy/Mirror
In most cases, the first defense line of data protection is to create a full copy of production data in your system. Infortrend Local Replication leverages the power EonStor DS storage systems to non-disruptively produce full data copies in a single system through volume mirror/copy. The copies created through volume mirror can be constantly synced with source or split as independent copies. When a RAID-protected volume fatally fails, the copy constantly synced can be leveraged for no-data-loss quick recovery. As to the split copies, they can be used to enhance operational resilience by allowing shared access of critical information among production and batch applications, such as testing, data mining, scientific analysis and tape backup. As business needs require, the split copies can be quickly re-synced with source. Besides volume mirror, users can also create copies independent from source through volume copy technology. These copies are ideal for time-critical applications since they are immediately available for use even before the copying process is fully completed. Same as the split copies created by volume mirror, the operations done to the independent copies won't have any influence on the service level of primary application or its data integrity.
The Differences Infortrend Local Replication Makes:
| IT Problems | With Infortrend Data Replication |
|---|---|
| Suffer from downtime and data loss when data volumes fail or virus, hardware failures or human errors cause data corruption | Quickly restore production, restore files or rollback data after storage suffers from logical or physical errors |
| Consume much space and system power for data backup | Create immediate, space-saving snapshot copies as recovery points with minimum capacity and performance impacts |
| Limited use of production data | Quickly create data copies and use them for secondary applications |
| Spend a lot of time performing data protection routines | Automate backup tasks such as copy creation , source-copy synchronization and capacity management |
| Compromise on data protection due to budget concerns | Build up the first defense line of data protection at affordable costs |
Infortrend Local Replication can bring you:
Increased Availability
- Immediately use disk-based full data copies to support applications when the source data volume fails; constantly mirrored copies ensure the least data loss
- Restore files and roll back data in seconds. Data are protected from accidental or malicious loss to ensure the highest system availability.
Space-Efficient, Low-Impact Data Protection
Instantly take point-in-time data images and use them as granular recovery points while consuming the minimum disk space and performance to store only data changes.
Flexible Data Copy Deployment
Split and re-sync mirroring between source and copy as business needs require; flexibly leverage independent copies of production data for secondary applications
Simplified Management
Provide scheduling and capacity control mechanism. Minimal manual intervention is required to perform data protection
Affordable Data Protection
Protect data beyond RAID capability while staying within tight budgets
Tight Application Integration
Ensure tight integration with leading operating systems and common business applications
