System i DR Options Topic of SafeData Buyer’s Guide
July 13, 2010 Alex Woodie
System i professionals who are interested in learning about the various options in disaster recovery should check out a new buyer’s guide recently released by SafeData, the provider of i/OS online backup and managed high availability services, which was recently acquired by Data Storage Corp. (DSC).
SafeData wrote its new paper, titled “Buyers Guide to Comparing IBM iSeries Recovery Options: A Comparison of Hot Site, High Availability and Virtual Recovery Strategies,” to help guide users through the process of analyzing and choosing a data protection and data recovery strategy.
The seven-page PDF explores the costs and benefits of three types of data protection, including hot sites (in which System i environments are re-created from tape at a separate facility); high availability (in which System i data is continuously replicated to a separate server); and virtualized recovery (which refers to the online System i backup service that SafeData is best known for).
According to the paper, using a hot site contains only one advantage: it’s cheap. On the downside are risks that include lost tapes, human error, and downtime that could extend to two days. The virtualized recovery option (like SafeData offers) is also cheap, but doesn’t rely on finicky tape, and can usually be completed in 10 hours or less. The one downside of virtualized recovery is that 10 hours of downtime may be too much. High availability offers the best protection of data and fastest recovery times, but is expensive and complicated to run, SafeData says.
The goal in putting the paper together was helping System i shops understand their options, says SafeData president Peter Briggs. “With the number of IBM iSeries data recovery options increasing, buyers should know that not all of them are right for their business,” Briggs says in a press release. “We’ve developed this guide to help IT professionals compare the differing levels of protection and recovery that solutions such as hot site, high availability, and virtual recovery each provide.”
