Dirk I also tried Data Domain and was not impressed. I now use Diligent's Protectier and its far more impressive. Its scalable, reasonably priced, achieves throughput of 200mb per second and better and factoring ratio's of Over 10 to 1

We're just testing a deduplication disk array from DataDomain with TSM. The compression ratio is much less than promised by the sales people. During the last 10 days of incremental backups we only achieved a ratio of 2.6:1. The disk array is very expensive and for the money you can buy more disks than you need without compression. -- Regards, Dirk Kastens Universitaet Osnabrueck, Rechenzentrum (Computer Center) Albrechtstr. 28, 49069 Osnabrueck, Germany Tel.: +49-541-969-2347, FAX: -2470 This e-mail, including any attached files, may contain confidential and privileged information for the sole use of the intended recipient.
