A deduplicated backup copy of data will certainly save on storage costs but does it provide the actual protection or does it just provide a false sense of security?
Most enterprise IT organizations are managing at least 100 TBs of data and some might even have a little bit more data these days. So 100 TBs seems to be a reasonable amount of data to scratch out a few calculations with regards to data transfer time and cost.
It takes 6 minutes to transfer 1 TB of data over Fiber Channel and over 2 hours (~133 minutes) to move 1 TB over GigE. That means it takes 10 hours to transfer 100TBs over Fiber Channel and ~9 days (~222 hours) over GigE.
Deduplication of the data can reduce bandwidth and storage during the backup and that is a good thing. However, it takes an hour to rehydrate 1.2TBs of deduplicated data back to usable format. At that rehydration-rate, it will take...
