About Backup and recovery software

Traditionally, backup and recovery software products had one purpose -- to make a copy of your data. But over the past few years, backup software products have evolved to include a whole host of functionality. Technologies such as continuous data protection (CDP), snapshot, data deduplication, replication, backup reporting tools and even data archiving have become features of, or are tightly integrated with, enterprise-class backup software applications. This section offers news and expert advice on data backup applications and tools such as CommVault Simpana, EMC NetWorker, IBM Tivoli Storage Manager, Symantec Backup Exec and NetBackup and more.
