I really don't know what Dell could improve to make this product better. I believe that for backup and deduplication, this is the top product.
I don't believe we have a better solution available now for fast backup and recovery speed. While Oracle may have a solution that promises zero data loss, for general-purpose backup and restore, I don't think we have a better solution capable of quickly restoring large amounts of data the way Dell PowerProtect Data Domain does.
We sell solutions from IBM, including a NAS-based one known as Spectrum Scale. I forgot the details, as I'm not involved in that project. We have one significant implementation of this product, but I'm not familiar with this specific type of storage.
I am involved in block solutions and I work with classical NAS systems such as Isilon and OceanStor. However, I don't only work with NAS systems that have nice GUIs; I also have experience with block storage. On the other hand, I don't work with Ceph or storages that are based on software-defined storage.
I work with OceanStor.
I work with OceanStor Dorado, OceanStor Protect, and all types of block and backup storages from OceanStor. I also work with Dell EMC; I forgot to mention Dell PowerProtect Data Domain. We also sell it because Dell PowerProtect Data Domain is the best product on the market for backup. When talking about block storages, I think only general-purpose block storages, and I mentioned that we use only Huawei and IBM storages.
In Serbia, public sector and enterprise customers are not using cloud technologies for backing up their data. Price is the main reason; they are reluctant to share information on the cloud. Presently, the only usage of Dell PowerProtect Data Domain is on-premises implementations here in Serbia.
I would rate this solution a nine out of ten.
