Disaster Recovery and Business Continuity - Optimize your Backup!

Posted by Ann Westerheim on 11/2/11 2:31 PM

WinterWeatherWe've had several days of power outages after a surprise October snow storm, and this serves as a good reminder to think about disaster planning and business continuity.  Today, businesses of all sizes need a data disaster recovery plan, which helps ensure the company will continue operations after experiencing some type of disaster due to:

  • Power outages
  • Severe Weather
  • Natural disaster
  • Hardware failure
  • Theft
  • Employee mistakes
  • A malicious act from a disgruntled employee or outsider
  • Loss of key personnel
  • Supply Chain Disruption
  • ...big disasters and small disasters...
While a snow storm may pose a few days of inconvenience, it's a good idea to plan for bigger disasters in advance.  People tend to "look on the bright side", but the statistics are scary:
  • According to the National Archives and Records Administration in Washington D.C., 93 percent of companies that lost their data center for 10 days or more due to a disaster filed for bankruptcy within one year of the disaster.

  • According to The Gartner Group, 34% of companies fail to test their tape backups, and of those that do, 77% have found tape back-up failures.

  • Data recovery services costs range from hundreds to thousands of dollars IF your hard drive can be recovered.

There are many aspects to a good disaster recovery plan to cover personnel, facilities, and technology.  One of the key areas we focus on is getting a solid data backup which is easy to do, and will alleviate a lot of pain when disaster strikes.

If you're still using tape backup, it's time to make a change RIGHT NOW.  Tape Backups are a “known evil,” and industry analysts estimate that anywhere from 40 to 70% of all attempted recoveries  from tapes fail.  Why?  Consider the tape backup process and the many points of potential failure that exist throughout:  You need to Install, update, and configure Backup Software, and determine exactly:  1) what to back up, and 2) when to back up.  Are you sure you're backing up ALL of your critical data, as often as you should?  Tapes also wear out over time .

Your backup should be:

  • Automatic - "set it and forget it" (except PLEASE check restores periodically, best practice is automatic verification)
  • Off-site - rather than relying on taking drives off site, we recommend on-line backup now that costs have come way down and make it affordable for small business.  Keeping your backup in the same building you work will leave you exposed in the event of a site disaster.  Best bet is to get your data FAR away.
  • Local copy too! - If your backup is only on-line, keep in mind that it can take a LONG time to get your data back when you need it.  With a redundant local copy, you get the best of both worlds.
  • Image based rather than file based.  If you do need to get new equipment, rather than spending all that time reloading all your applications (IF you can find the disks), and image-based backup basically serves as a clone.

For clients who have a high cost of down-time, we strongly urge them to consider an optimized backup and disaster recovery service.
