Continuous Data Availability Features
Timely access to critical data is often the difference between the success or failure of a business. Data must be available to
users when they need it. In today’s global economy, critical files and databases must often be available 24 hours per day. If
access to a critical system is interrupted for any reason, alternative systems must be able to take over the load automatically
and transparently. Disaster recovery capabilities must be available so that if the worst happens and and a site is completely
disabled, critical data can be restored and available online in a few minutes or, at most, a few hours.
VERITAS NetBackup can be an effective way to provide cost effective disaster recovery protection for mission critical data.
NetBackup delivers online high performance backups of database, file system, and application-specific data, with minimal
impact on users or applications. In addition to fast backups, NetBackup also provides many methods to recover data quickly.
VERITAS NetBackup is an industry leader in providing continuous data availability for all types of mission critical data during
backup operations.
Online Backups of Relational Database Management Systems (RDBMS)
VERITAS NetBackup supports high performance, online database and application-specific backups across multiple vendors in
addition to providing sophisticated support for older versions of databases (please see the “Database Backup Methods”
section below).
NetBackup offers completely online, highly reliable backup solutions for all major databases, including Oracle (RMAN, RMAN
Proxy Copy, and EBU), Sybase, Informix, DB2, SAP R/3, Microsoft SQL Server, Microsoft Exchange, and Lotus Notes. With
these database solutions, online backups for other major applications such as PeopleSoft, Baan, and SAS are enabled. No
matter what the application or environment, NetBackup ensures continuous data availability and complete data protection.
Database backup performance is critical to data availability, even in online database backup configurations. The NetBackup
architecture enables multiple parallel data streams to be pushed to a NetBackup server on the local machine or across the
network (see Figure 4). On systems where backup media transfer rates far exceed disk or network transfer rates, data
streams from multiple disks and clients can be combined into a single stream to drive the offline media at its peak rates –
this facility is called multiplexing. Performance scales in a nearly linear manner as additional peripheral devices and backup
servers are added incrementally.
