The other two can do so, but are really not priced nor designed specifically for backup target storage.

Of the 3 vendors you asked about, I am going to repeat myself, PowerProtect DD is ONLY useful as a target storage for backups. I think you need to define what it is you really need. Their FlashBlades are all flash file and object storage systems. Good performers but overkill and way too expensive for backup target storage. Pure Storage FlashArray//X or //C are block all-flash storage arrays. It's a solid all around storage system with NetApp pioneered capabilities, but expensive as a backup storage target. It can be all HDD, hybrid HDD and SSD, or all SSD (all-flash FAS or AFF). NetApp FAS is a general-purpose storage system for blocks and files.

Most backup target storage is all HDD although some are hybrid SSD and HDD. I would suggest you take a hard look at a variety of backup target storage vendors including, Infinidat InfiniGuard, ExaGrid, Quantum, StorONE, iXsystems, and many more. Especially when measuring restore performance. There are much faster, cheaper, and more advanced backup target storage. Albeit, it's a bit pricey and underperforming. If that is what you want, it does what it's supposed to do. It is ONLY useful as target storage for backups. PowerProtect DD is Dell's latest version of Data Domain.

I know there are a number of variables but EMC is quoting us 6:1, we are seeing 7:1 in a POC but a colleague tells me he is getting 2:1. The dedupe ratio started from 3:1 and ended with 11:1 after we have done 3 cycle of full backup within 2 weeks time for the PoC.Ĭan you help out a colleague with the following question about Data Domain:Ĭan anyone share their real-life deduplication ratios using Data Domain?

And it really depends on if you enable dd boost and how many round of full backup have been completed.
