Hi,
Writing a de-dupe backup product isn't easy. EMC bought Avamar and Symantec bought Data Center Technologies to get their respective products. I don't know of any other de-dupe companies for IBM to acquire, so they'll have to write their own. That may take them a bit longer.
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
