BACKUP DATA ARCHIVES
Traditional backup platforms are not suited for archival data storage. An archive differs from a backup because the data may not be used for months or even years, but must be accessed quickly when needed. Files can be archived to any disk storage system. Recently content-addressed storage (CAS) has appeared to support archiving efforts.

BACKUP DATA SECURITY
Storage administrators are increasingly relying on encryption technologies to guard sensitive data on tape, disk or WAN.

BACKUP SOFTWARE
Most companies back up their data during evenings and weekends. As a result, backup software performs more and more tasks, including keeping track of backup schedules, managing the timely transfer of data volumes to target tape or disk locations, handling compression to reduce media use and speed up the backup process, and even including encryption to secure data.

CDP
Continuous data protection (CDP) is a technology in which data is backed up whenever a change is made. In effect, CDP creates an electronic journal of complete storage snapshots, one snapshot for each instant in time that a change to the data occurs.

DISK-BASED BACKUP
These days, traditional tape systems often do not meet the demands of today's busy data centers, and administrators are turning to disk-based storage for data protection, backup tasks and archival storage.

REMOTE DATA BACKUP
Branch offices are far more common and frequent today as companies seek to extend their global reach and improve regional/local service. But as more critical business data resides outside of the primary corporate data center, storage administrators are challenged to protect that data without impairing productivity. Moving data from remote sites or users to a central location requires an understanding of remote backup technologies.

TAPE BACKUP
Tape backup technology provides low-cost long-term data storage. Although backup performance is slower than disk, users of tape backup can store a large volume of data at a relatively low price.

DATA BACKUP COPIES
Today, backup copies go far beyond simple disk-to-disk file transfers. There's growing specialization and diversity in data backup copies -- allowing storage administrators to select copy platforms that meet specific requirements for performance and retention.
