If a company is of a size that it would lose millions over a week or two (a rough estimate of the 'time consuming' restore procedure you outline) it will have a backup regime that does involve different generations on removable media, and very definitely not just a copy to another set of SSDs of the same vendor and of the same age. We're talking SAS drives, not exactly the stuff a ten-head business chooses for their data storage.
Yes, the procedure you describe is possible but if there's a business that has to resort to that to recover their data they deserve to go under.
