How much of your work product can you afford to lose?
If your computer or the server holding your data is down, how long can you wait until things are back to normal?
Answering those two questions is key to a good backup plan.
The first— how much work product can you afford to lose? — addresses your “Recovery Point Objective” or RPO. Your RPO tells you how frequently you have to backup.
The second— how long can you wait until things are back to normal? — defines your “Recovery Time Objective” or RTO. Your RTO will help you choose the backup mechanism(s) used: USB drives, tape, cloud, etc.
Example: if you produce only 3 or 4 computerized invoices a month, all of which could easily be recreated from recent paper documents and receipts, then your RPO may be 1 month (that is: you could easily redo the last month’s invoices, but anything before that would become problematic). However, if you’re producing hundreds of invoices a day, or other work product that can’t be easily recreated, then your RPO may be 15 minutes or less.
For recovery time objective, restoring from a cloud based backup may take longer than a local source like tape or USB hard drive. And while it may seem intuitive that someone who needs to backup frequently will also need to restore quickly, that isn’t always the case.
There are many other considerations that go into designing a good backup plan, including balancing budgetary concerns. It makes no sense designing a perfect backup plan you can’t afford; any more than it does having a backup and recovery plan that won’t deliver when you need it to.
