Two different things.
WHAT A BACKUP IS
A copy of your data.
WHAT CONTINUITY IS
The ability to keep operating.
WHY THE DISTINCTION MATTERS
A backup you cannot restore quickly does not keep you operating.
WHAT CONTINUITY REQUIRES BEYOND BACKUPS
Knowing how to restore Having access to the accounts needed Knowing what to do and in what order Someone able to do it A way to tell customers
THAT LAST ONE
Frequently forgotten. If your site and email are down, how do you reach customers?
WHAT A PLAN NEEDS
What to do Who does it What they need access to Where the information is
WHERE THE PLAN SHOULD LIVE
Somewhere reachable when your systems are not.
Not on the server. Not only in your email.
WHAT TO TEST
Whether you could actually execute it.
