I've been personally impacted by lost tapes

Hi Folks,

Yesterday I received a letter in the mail at home that started off:

Dear Sir or Madam,

We are writing to let you know that computer tapes containing some of your personal information were lost while being transported to an off-site storage facility by our archive services vendor. While we have no reason to believe that this information has been accessed or used inappropriately, we deeply regret that this incident occurred....

So the first question I have is how does an archive vendor lose tapes? How hard can it be to take the tapes from your customer put them in a secure truck and drive them to the storage facility? Isn't that your whole business model - you will pick up, transport and store these tapes safely and securely 100% of the time?

Now I understand that any activity with humans involved cannot be guaranteed to work 100% of the time. So what really happened? A bit more of an explanation would have been helpful, such as the truck was in an inadvertent accident and the contents of the truck were spilled into a river or all over the highway and could not all be recovered. Without more details I'm left wondering did someone make off with the tapes by accident or on purpose? Or was this just sloppy work by the company?

Anyway, I hope this is a call to action for this company to do at least two things to prevent such an incident in the future.

1. Look into tape encryption such as the LTO-4 offers. I would have been more much pleased if that second sentence read "While the tapes were physically lost, the data they contained cannot be accessed or read by anyone because the data on the tapes is securely encrypted with sophisticated technology requiring encryption keys to make the data readable. Our security policy ensures that these keys are always stored in or transported to physically separate locations from the computer tapes."

2. Consider the use of replication and electronic vaulting for moving data off-site for archiving. With new technologies such as deduplication and low-bandwidth replication, this company would perhaps be able to reduce the amount of data that is stored on tapes and physically transported to archive storage. Again, I don't know the specifics here, but as an example let's say this company had four sites that they were backing up to data to tape and transporting those tapes to off-site archives. With replication and electronic vaulting, they could replicate data from three of their sites to just one site for backup to tapes and then only have to move tapes from the one site to archive storage thereby reducing their risk exposure by 75%.

If you're worried about how a similar incident could impact your company and what risks are involved HP is here to help. We can work with you to significantly reduce your data security exposure from the desktop to your data center. On the storage side, we offer a FREE storage security risk assessment.

Examples of Data Deduplication Ratios for File Serving, SQL and Exchange

By Jim Hankins

If you remember back in my HP Deduplication - Part 1 post when we announced our new deduplication products back in June, I said that the deduplication ratio you can expect from a product can vary based on a number of factors. We now can share with you deduplication test results from our D2D4000 Backup System conducted by a 3rd party, Binary Testing Ltd.

Binary Testing conducted testing that backed up and deduplicated data for file serving, SQL and Exchange environments with various data change rates over a simulated three month backup period. The results can be found here: http://h71028.www7.hp.com/ERC/downloads/4AA2-0799ENW.pdf

Again, your mileage may vary but this report should give you some idea of what's possible if your business runs these types of applications.

New "Impossible IT --- Virtualized!" video

Watch as "IT Guy" Al Jones sweats while dangled above a Piranha tank. He has to perform 3 tasks on the HP StorageWorks Virtual Library System before he becomes fish food.

Here's the link to the video: http://www.youtube.com/watch?v=aqN2Q-yZemQ

This is the second of the Impossible IT videos. If you remember the "runaway train" in the first one, then you MUST see this one.

For a refresh on the first Impossible IT video, go here: http://www.youtube.com/watch?v=HmlsT_rMkOc

Enjoy!
