Where a customer has a requirement to restore data from a Secondary Copy, rather than restoring all of the data directly from that Secondary Copy, it would be useful if there were an option to use something akin to the DASH Copy process to transmit only the blocks that are not available via the Primary Copy.
I could see this being really beneficial for restoring back to remote office locations, and for reducing egress costs when recovering from cloud (especially from Archive tier).
Alternatively, something like a Copy Back option could work, where jobs can be copied back to the Primary Copy, leveraging DASH Copy.
