Good Planning Requires Follow-up

In Backup, Business Continuity, Cloud Computing, Disaster Recovery, Security Management, Vendor Management on August 31, 2010 at 07:29

Many organizations still believe that having a great business continuity plan, complete with a solid contract with a third-party recovery partner, is enough to protect them from the inevitable.  As American Eagle Outfitters found, however, this is not enough.

According to Evan Schuman from, which monitors retail Web sites, the outage began with series of server failures.

Schuman, who said he spoke with an unnamed IT source at American Eagle, said a storage drive failed at an IBM off-site hosting facility. That failure was followed by a secondary backup disk drive failure. Once the drives were replaced, the company attempted a restore of about 400GB of data from backup, but the Oracle backup utility failed, possibly as a result of data corruption. Finally, American Eagle Outfitters attempted to restore its data from its disaster recovery site, only to discover the site wasn’t ready and could not get the logs up and running.

“I know they were supposed to have completed it with Oracle Data Guard, but apparently it must have fallen off the priority list in the past few months,” the source told Schuman.

This is the description of events leading to an eight-day outage for the company’s customer-facing website.  There are one or two lessons for all of us here.

First, when was the last time American Eagle asked IBM for its processes for dealing with unusual outages?  How often did they review IBM’s processes for testing incident response?  This is as much American Eagle’s responsibility as it is the off-site vendor’s.

Second, when was the last time backup tests were performed?  What are the requirements for this in the contract and how is compliance validated?

Based on this article, there’s no evidence that American Eagle was intentionally negligent.  They simply made the mistake of assuming; that is, assuming their service providers were practicing due diligence.  When using cloud or any other third-party services, we still have a responsibility to inspect what we expect.

Review of the ioSafe Solo Backup/DR Drive

In Backup, Business Continuity, Data Security, Disaster Recovery, Physical Security, Risk Management on July 4, 2009 at 17:56

I don’t get excited about technology very much anymore.  After almost 30 years in this business, I’ve become rather jaded to most emerging technology.  So I have one thing to say about the ioSafe Solo drive—WOW!!

I received an evaluation unit from ioSafe a couple of days ago.  It came in a plain white box, but it weighed quite a bit.  Big piece of iron I have to spend an afternoon configuring, I thought.  So I waited until the weekend.  Removing the drive from the box I found the drive unit, a USB cable (which closely resembles the cable I use on my USB printer), and a power cable. The drive unit is about the size of a toaster.  But unlike my toaster, it weighs about 15 pounds. 

The manual wasn’t much.  Since I was connecting the drive to my laptop running Windows XP SP2, the installation instructions pretty much consisted of: 1) plug the drive into an outlet, 2) plug the USB cable into the drive and into the computer, and 3) turn on the drive.  This was good.  I like simple.

I followed the directions, and 20 seconds after I turned on the drive I had a new 500 GB drive connected and ready for action.  According to the manual, Apple computer users will have to do some formatting work before they can use the unit.

Now you might be asking, “so what?”  Well, there is more to this drive than meets the eye.  Within 5 minutes of unpacking the gear, I had a backup drive which provides the following:

  • Fire protection for temperatures reaching 1550 degrees Fahrenheit for 30 minutes (tested per the ASTM E119 protocol)
  • Water protection, tested for immersion up to 10 feet for 72 hours
  • FloSafe air cooled, providing forced air cooling through plastic vents which melt shut to protect the unit when ambient temperature reaches 200 degrees Fahrenheit
  • Metal case which can be easily bolted to the floor or secured with a cable lock
  • A three year warranty and ioSafe’s data recovery services for one year

Additional features include 7200 rpm drives and USB 1.0 and 2.0 support, with data transfer rates up to 480 Mb/s.

I was pretty interested in this drive by this time.  It’s a perfect backup solution for my home office and the restaurant we own.  So I looked up the price.  I was not disappointed.  The ioSafe Solo can be ordered with one of three data capacities, as listed below:

  • 500 GB at $149
  • 1 TB at $229
  • 1.5 TB at $299

You can upgrade the data recovery service from one year to up to five years, adding up to $100 to each of the prices listed.  These are retail prices.  A quick look at shows discounted pricing.  If you are an Amazon Prime customer with free shipping, you can also save the $25 or so it takes to get it to your door.

So my Solo unit sits next to my laptop, quietly protecting my data.  Quiet is relative, but it emits a very, very low hum which is almost undetectable in a quiet room and absolutely absent when listening to  It looks pretty good, too, with blue lights on the front indicating a power on state. 

This is an excellent drive at an affordable price.  If you currently pay monthly fees to support over-the-Web backups, if you still use backup tapes, or if you have simply decided it’s too much trouble to look for and implement the right backup solution, you should definitely take a look at the ioSafe Solo.  I highly recommend it.

AVSIM: Real world example of the value of offsite backups

In Backup, Disaster Recovery, Hacking on May 18, 2009 at 08:00

The owners of AVSIM, an important resource for Microsoft Flight Simulator users, worked for 13 years to build a well respected site.  Using two servers, they conscientiously backed up one to the other, confident they were protected.  That confidence was shattered this month when a hacker destroyed the site, including both servers.  Since no offsite backup–or even an off-server backup–was available, it was impossible to recover.

There is a lesson here for all organizations.  If you have a server or other storage containing critical business information, make sure it is backed up to an offsite location.  Even if the probability is low that fire, tornadoes, hurricanes, and a host of other natural threats may take out your facility, there is always the hacker community which is always looking for a new challenge.

We always talk about the importance of offsite backups, but sometimes it takes an actual example to make managers sign a check.  Maybe that is the proverbial silver lining in this story.

New centralized storage for SMBs

In Backup, Business Continuity, Data Security on March 12, 2009 at 07:23

Keeping all your sensitive information in a centralized location helps with security.  However, SMBs with large storage needs (or home users with way too much audio-video gear) may find the new D-Link SAN array useful.

D-Link DSN 1100

D-Link DSN 1100

No, it’s not a big EMC device, but most small businesses don’t need and can’t afford a big piece of storage iron.  So for about $1800, they can get most of the benefits of an enterprise SAN, including:

  • Up to 7.5TB of storage
  • RAID 0, 1, 1+0 and 5
  • CHAP authentication
  • Four 1Gb ports
  • SSL security to manage console
  • VLAN zoning for network segmentation
  • Up to 72 hours of battery backup

It’s everything a SMB needs to consolidate, protect, and ensure available of sensitive information.
