Today's advances in data backup, restore and archival storage technologies offer reliable and cost-effective data protection and business continuity. Your options include disk-to-disk (D2D), network attached storage (NAS) and tape (just to mention a few), in addition to storage software to manage your data protection solution. A comprehensive data protection system is not usually a standalone solution, however—the greatest level of data protection may come from a combination of technologies.
Storage data protection has traditionally revolved around tape media. However, D2D backups that use tape as a long-term storage media (referred to as D2D2T) now provide organizations with superior benefits. When evaluating backup solutions for your organization, consider the following criteria:
•
Is the solution easy to use, with multitier backup options?
•
Is the solution integrated with your business needs?
•
Will the solution be cost-effective whether you're backing up a single server or several multisite servers?
•
Can you depend on the solution to perform reliably and worry-free both in terms of initial implementation and long-term operation?
Most backup solutions fall into one of two broad categories: LAN-based solutions, which use shared storage devices attached to a local area network (LAN), or direct attached storage (DAS), in which backup storage devices connect directly to a server or workstation. This guide covers LAN-based and DAS backup technologies to help you identify a comprehensive backup solution that's best for your business. You'll also learn about solutions for remote offices and mobile users, which have unique backup challenges.
Tip: You may find that your business is initially suited to both a DAS and LAN-based solution. As your business grows and your data capacity needs increase, a storage area network (SAN) may be a more likely approach to data protection.
