® 4 ™ © 2012 IBM Corporation Virtual Tape – Why is it interesting? Small Servers can’t optimize a tape drive Offsite Shipments are Costly and a BotherTapes are Hard to Manage Writing WaitingWaitingWaiting Small Backups don’t fill a tape Virtual tape can provide multiple virtual drives Virtual tape can make virtual volumes of any size Virtual tape keeps all the volumes inside the device Virtual tape can transmit them to a remote site

10
® 10 ™ © 2012 IBM Corporation Deduplication Algorithms – Post vs Inline Backups run first without de-dup Separate de-dup algorithm runs thereafter Requires extra disk space to hold the interim full-sized copy of the backup Used when the de-dup algorithm is not fast enough to run inline Inline De-Duplication (eg HyperFactor) Post Processing Deduplication De-dup runs as part of backup process Uses less disk Once save is done, the entire process is done Only possible with a fast de-dup algorithm like ProtecTIER HyperFactor © 2012 IBM Corporation

Actual environmental costs and performance characteristics may vary by customer. Information concerning non-IBM products was obtained from a supplier of these products, published announcement material, or other publicly available sources and does not constitute an endorsement of such products by IBM. Sources for non-IBM list prices and performance numbers are taken from publicly available information, including vendor announcements and vendor worldwide homepages. IBM has not tested these products and cannot confirm the accuracy of performance, capability, or any other claims related to non-IBM products. Questions on the capability of non-IBM products should be addressed to the supplier of those products. All statements regarding IBM future direction and intent are subject to change or withdrawal without notice, and represent goals and objectives only. Some information addresses anticipated future capabilities. Such information is not intended as a definitive statement of a commitment to specific levels of performance, function or delivery schedules with respect to any future products. Such commitments are only made in IBM product announcements. The information is presented here to communicate IBM's current investment and development activities as a good faith effort to help with our customers' future planning. Performance is based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput or performance that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput or performance improvements equivalent to the ratios stated here. Prices are suggested U.S. list prices and are subject to change without notice. Contact your IBM representative or Business Partner for the most current pricing in your geography.
