Questions & Answers
When do I use the SNMP Module versus the HP-IT/Operations Agent?
Use the SNMP module to export messages and trigger alerts on the SNMP consoles of Sun NetManager, HP OpsCenter, IBM NetView and other network management consoles. The HP-IT/Operations Agent is for those customers who wish to administer and monitor their NetWorker for HP-UX servers from the HP IT/Operations console.
How are Storage Nodes licensed?
Storage Nodes are licensed on a per-node basis and are affiliated with a single NetWorker server (as a client). Before adding a remote device to run on a Storage Node, a Storage Node enabler must be entered on the server running NetWorker. If the Storage Node is applied to a computer running a different OS than the NetWorker server, the appropriate ClientPak enabler must also be entered.
When should a Storage Node be added instead of another NetWorker Server?
As long as there is adequate network reliability for the Storage Node and NetWorker server to communicate, the addition of a Storage Node is possible. Reasons for adding a Storage Node apply in scenarios such as these:
What are the benefits of using multi-tiered storage management with NetWorker?
The built-in multi-tiered staging capability of NetWorker 5.1 allows you to first backup, archive and recover data to high speed disk devices. This can significantly increase the speed of backup, archive, and HSM storage management operations. Several pre-defined policies can manage the capacity of this intermediate disk storage to move backup and archive data to slower and less expensive media. Multi-tiered operations support the ability to automatically move data from any one media or device to another, based on customer specified thresholds.
How Are Clients of Different OSs Managed by a NetWorker Server?
NetWorker works on both Windows NT, UNIX, and NetWare server platforms and protects data in mixed client environments. NetWorker servers provide a pre-configured number of client connections and client software for the server operating system. In order to protect a different operating system than the server, such as Windows NT, OS/2, NetWare, Macintosh, or another UNIX system, you must purchase the appropriate ClientPak, and any additional client connections you may require. All ClientPak software is supported via TCP/IP.
How Can I Centralize Administration Tasks?
Two ways. A NetWorker administration console can safely and reliably administer any number of NetWorker servers for which it has been given access. In addition, if Storage Nodes are installed, then a single NetWorker server administration console can administer multiple storage devices attached to multiple machines.
What is the OpenTape Format?
The NetWorker OpenTape format is the only media format that is secure, self-describing and supports high-performance, multiplexed backup, recover, archive and HSM storage management functions. In addition, OpenTape can be used on any operating system, which allows any NetWorker tape to be used by any NetWorker server. Secure refers to the ability to continue the recover function through bad sections of media. Tar and its variants do not have this capability. Self describing refers to the tape's ability to tell an application what is contained on the media without having to copy the information from tape into a file system or database.
How Does the Replica DR Module Automate Disaster Recovery for Windows NT and NetWare Platforms?
The Replica Module offers complete secure disaster recovery and "bare metal" recovery capabilities. This module will back up and pre-package critical system information and libraries at the block level - without interrupting current operations. Customers can use NetWorker's pre- and post- processing capabilities to initiate Replica disaster recovery backups, automatically creating a series of diskettes that can "re-build" the protected client operating system. Replica restores crashed servers - including boot volume, disk partitions, security (NT Registry, NetWare Bindery/NODS), and operating system libraries. "Bare metal" recovery capabilities provide end users an easy and fast method for re-establishing critical functionality from Replica disaster recovery diskettes and tape without rebuilding disk partitions or separately reinstalling the network operating system.
