Open-E DSS V7
Disaster Recovery is one of the most essential strategies for securing lost data against disasters. It includes all processes and procedures that are performed in order to prevent large failures and to avoid the consequences by keeping copies of data. With a consistent strategy, you are able to quickly recover business-critical files and applications of your IT infrastructure - ensuring business continuity and minimization of data loss.
Zero-data-loss protection – Synchronous failover ensures that volumes are identical on all systems. The source server doesn’t allow changes to data until the destination server has confirmed that all volumes have been updated. Critical data is protected at the highest level, but to avoid performance constraints this technology is mostly used in local area networks (LAN).
Flexibility – Available for NAS, iSCSI and FC volumes. This technology is block-based and therefore available for all volume types which can be created with Open-E software.
Snapshots – A point-in-time image of any volume. With Open-E Data Storage Software you can create multiple snapshots per logical volume. Snapshots can be used for both consistent and temporary backup, while you still have uninterrupted and complete access to the Logical Volume. Files can be recovered from previous snapshots if accidentally deleted or modified.
High Availability – A professional, highly available storage requires synchronous replication. The failover can work only if data on the secondary volumes are identical to the primary volumes, otherwise your clients will crash and downtime will be inevitable. In Open-E software, synchronous volume replication prepares your second system to take over the services at all times and performs the failover unnoticed by your client.
