Enterprise Backup Solution for Legato NetWorker

Enterprise Backup Solution for Legato NetWorker 14

The Secure Path software:
•
Detects the failure of I/O operations to complete on a failed path
•
Automatically reroutes all traffic to the second path
Controller and path failover is completed without disruption or data loss.
The Secure Path management utility provides continuous monitoring capability and identifies
failed paths and failed-over storage units. To facilitate static load balancing, storage units can be
moved between paths using simple drag-and-drop operations.
The integration of Secure Path, Windows NT Clustering, and StorageWorks RAID Array Fibre
Channel technology provides the maximum level of fault tolerance, data availability, and
performance required for mission-critical environments.
Legato NetWorker Power Edition
Legato NetWorker Power Edition optimizes EBS performance and is a solution for customers
with large servers, or the requirement to drive high-speed devices. Power Edition features
enhance local backup to dramatically increase local throughput while minimizing the use of
system resources.
Power Edition takes advantage of the high throughput of the leading enterprise-class tape devices.
Performance is scaled linearly as additional fast storage devices are added to the system, up to the
limit of the server’s I/O bandwidth.
Immediate Save and Recover
When backing up data from the Power Edition server or storage node, Immediate Save and
Recover speeds up data transfer. The processor load is reduced because the data is transferred
within memory. Power Edition enables local backup and recover to bypass the processor
overhead of networking protocols.
Storage Nodes
Each Power Edition server can have several storage nodes attached and each node can have
multiple devices. This configuration enables the transmission of a maximum of 512 parallel
backup sessions with a maximum of 256 devices. Because Power Edition storage nodes store data
locally and maintain all of the metadata associated with the controlling Power Edition server,
backup speed and efficiency is enhanced. Immediate Save and Recover is used to back up and
recover data hosted on a storage node.
High-Speed Device Support
Power Edition supports a broad range of autochangers and silo tape library models. Autochangers
and silos can contain multiple storage devices (tape drives or optical drives) and can automate the
tasks of loading, unloading, and labeling storage media. This automation allows backups to
proceed without intervention. High-speed devices are configured for higher throughput, so they
can write data to media faster and in larger blocks.
