There are several approaches to increasing data availability in the face of hardware, software, or even site failures. Backups provide a way to recover lost data from an archival medium (tape or disk). Redundant hardware technologies also help mitigate the damage caused by hardware issues or failures. Mirroring provides a third mechanism to facilitate data availability and minimize downtime.
SnapMirror offers a fast and flexible enterprise solution for mirroring or replicating data over local area, wide area, and Fibre Channel (FC) networks. SnapMirror can be a key component in implementing enterprise data protection strategies. If a disaster occurs at a source site, businesses can access mission-critical data from a replica on a remote N series storage system for uninterrupted operation.
