We are using AFF for a few clients. It's a specific type of data we use for these arrays, not like a block kind of thing or regular data. A few clients have particular requirements about where we put all the data. We are primarily using FAS, and we have around four or five AFF boxes. We don't deal with AFF regularly.
We're not currently using NetApp Cloud Backup, but we're planning on implementing it. I'm not sure because my architect is the one who manages the end-to-end services for NetApp. He makes all the decisions on the NetApp side whether we use AFF or FAS. AFF is a unified storage box, so we route certain data to AFF.
