count on any one single security mechanism to keep you safe.
Instead, you should use a layered approach that uses a variety
of security products and techniques. That way, if an attacker or
malware ends up penetrating one of your defenses, other
defensive measures will be in place to help prevent the attack
from being successful.
Having a good backup strategy is an essential part of
countering external security threats. Your backups are your last
line of defense and are crucial for putting everything back to
normal in the event that an attack is successful.
Imagine for example that your organization's data is encrypted
by ransomware. When this happens, you generally have two
choices: you can pay the ransom, or you can restore a backup.
Paying the ransom is usually a bad idea. It emboldens the
attacker, and there is no guarantee that you will get your data
back. It is far better to have the ability to restore your data
from backup than to be forced into paying a ransom.
I have heard stories of organizations
becoming re-infected by ransomware only
minutes after paying the ransom.
Reason 6: Managing Hybrid Deployments
and Migrations
A sixth reason why it is so important to back up your Microsoft
365 environment is that doing so is an important part of
maintaining consistency. Imagine for a moment that you have a
hybrid environment with half of your Teams users' mailboxes
residing in an on-premises Exchange Server, and the other half
existing in the Microsoft 365 cloud. Does it really make sense
