Data Replication License for EonStor DS series. Includes Snapshot backup and volume copy/mirror (local data replication) functions.
Data 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 Data 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 Data 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.
Data 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 Data 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 wont have any influence on the service level of primary application or its data integrity.
