What If Disaster Strikes?
A Disaster Recovery Plan?
Disaster recovery is a very broad topic, but is essentially a plan for how your organization will deal with a disaster.
Your goal is to keep your business running and to minimize down-time and loss.

Important data should be backed up weekly.
How Often Should We Backup?
Data that doesn't change often should maybe be backed up at least monthly.
Transactional data may need to be backed up every few minutes or sooner.
Important data should be backed up weekly.
How Often Should We Backup?
Data that doesn't change often should maybe be backed up at least monthly.
Transactional data may need to be backed up every few minutes or sooner.
It all depends on how much data you can lose and how fast you need it back.
Backups should be stored securely.
Don't Forget About Security
If you use encryption, make sure to also backup the keys used to encrypt your data.
And make sure to also store those keys offsite.
How long should you keep your backups?
Don't Forget About Data Retention

Don't Forget About Data Retention
It's much more difficult to steal data that you've already deleted.

So We're Good, Right?
I backup all the time. I keep them safe. I don't need to worry.
