Three Questions To Ask Yourself When Choosing a Backup Solution:

Three Questions When Choosing a Backup Solution:

  1. What is your RTO?
  2. What is your RPO?
  3. What is your budget?

RTO – Recovery Time Objective -How Quickly Can Your Business Recover?RTO graph

Your Recovery Time Objective (RTO) is the maximum amount of time your systems can be out of commission — from when a disruption occurs to the moment your system is available again. Another way to think of this is “how long can you afford to be without your email, accounting, order entry, etc.?”

On-line Backup

Recovering data, applications and system files over an internet connection sounds easy enough, but it can be a painfully slow process.  You have to consider not only the download bandwidth of your own network connection, but the amount of bandwidth alloted by the company, Mozy Online, iBackup,iDrive, etc. that you use. Typically there is a very large pipe to back it up anda very small pipe to get it back.

RPO – Recovery Point Objective – How Much Data Can You Afford to Lose?

RPO is a measure of the maximum time period in which data mightbe lost if there is data loss, not a direct measure of how much data might be lost.  The RPO is expressed backward in time from the instant at which the failure occurs, and can be specified in seconds, minutes, hours, or days.  Once the RPO has been defined, it determines the minimum frequency with which backups must be made. This, along with the Recovery Time Objective, determines the optimal disaster recovery technologies and procedures.

  • If your backup runs once per day and is taken off-site once per week, your RPO is 1 week.  You could conceivably lose 1 weeks worth of data.
  • If your backup runs once per day and is replicated offsite once per day, your RPO is 48 hours.  You could conceivably lose 48 hours worth of data.
  • If your backup runs every 15 minutes and is replicated offsite throughout the day, your RPO is 15 minutes plus replication time which depends on your internet speed.  This could be as low as 20 minutes total up to several hours if you have a slow connection.

RTO and the RPO have a very significant effect on the design of your Backup and Disaster Recovery Solution.

Budget – What Can You Afford?

How much money do you have available to protect your data and systems? You may want local and offsite, high availability, instant recovery, blah, blah, blah, until you see the price tag. The lower the RPO and RTO limits are, the higher the price.  You have to find a balance between your pain threshold and what you can afford.
