Ok, so assuming the primary storage takes care of DR backups, active/active, sync/async replication, physical risks [earth(quake), fire, wind, water, power], assures ease of standing up the DR environment after a whoopsie, isn't from a rent-seeking company that does planned obsolescence (i.e., there's a way to upgrade h/w without having to take it down).
Thank you, I don't mean to say everything is already accounted for, just trying to surface the kind of issues/things to consider. ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On Sunday, July 5, 2020 11:07 PM, retired mainframer <retired-mainfra...@q.com> wrote: > You might want to consider whether transportability is an issue.
