Deduplication of recovered data
One of my customer wants to store old data which is recovery sets of their old Exchange backups. When backups were taken there was nothing called dedupe etc.
We are looking for a storage where his recovered data can be stored and he gets it deduplicated Ex. 2 TB of SQL databases recovered for April 2010 in one folder and then again for May 2010 in second folder. We are looking for a device that would occupy not 4 TB but something like 2.5 TB types depending on the dedupe achived.
Would Data Domain be able to provide this? We actually want to use the same device for future backups also so whated ot explre this?

some backup tools provide native compression, Data Domain will try to dedupe and then compress ..how much is uncertain.

In this case, the backup tool will recover the data and give it back to us in native format, we just need to store it on a device and are looking for something that gives dedupe benefits so that to keep 50 copies of 2 TB databases, we don't need 100 TB of storage.

i see, Data Domain is an excellent choice for data bases, especially if there are multiple of the same thing. Database typically get compressed and deduped very well. Will it only use 2TB for 50 copies not likely but you will get pretty good dedupe for sure.
