Testing Restores on Backups

We’ve attended plenty of events that preach the importance of backup, but rarely is it approached from what is essentially at the heart of data protection – data recovery. For example, did you know that DLT tapes (still the media of choice across the board) are designed to be overwritten only 5 times? According to our valued partners at SonicWALL, Inc., administrators report that they use DLT tapes an average of 12 times. Also, something like 73% of the backed up data surveyed, was unrecoverable!!! Point being, a backup is only as secure as its recovery plan.

The recommendation here is to run periodic recovery drills to test the viability of the data protection scheme. Taking SonicWall’s lead, we here at 318, Inc. would like to begin a vigorous push with all our clients towards increasing the awareness of the importance of data recovery. Another tidbit: 93% of companies that had suffered a major loss of data, were out of business within one year. Far too many systems administrators’ careers have ended abruptly due to recovery-plan negligence and we’ve all seen it happen… nuff said.

A few more interesting points on the subject of data loss (if data loss can be considered interesting…):

The speed of recovery is as important as anything else. The example was given of when, during the early days of eBay, their servers were brought down under attack and, though their data was safely backed up, it took 2.5 days to recover it. Million$ lost in revenue! Administrators should design a plan that includes rapid recovery of the most recent and most critical data, allowing the affected party(s) to resume their daily tasks while recovery of the older, less important files continue to restore.
People are, by far, the biggest challenge to security – eg. Passwords taped to monitor screens; using “password” as their password, etc. Only strict security company policies and education can combat this security leak. Even the most secure server in the world can be easily compromised by an employee walking through an airport with log-on credentials for that server, written with a Sharpie on the outside of their laptop case (it was an agent from the U.S. Homeland Security Department -true story – as the laptop came out of security’s X-ray scanner, it was mistakenly handed to the wrong person!).
Small to medium businesses are hit hardest by data loss. They usually have fewer resources to invest in protecting their data and are usually the ones least likely to appreciate the importance of a strong backup/recovery scheme.
Data protection is more important than ever now, considering that cyber-criminals are making approximately 6 times more money with far fewer expenditures than organized crime ever did, even in its hey day.
On the subject of data security, no discussion is complete without extensive planning for protecting the network that the data resides on. “Controlling the flow of data can be as difficult as herding cats.” For network security, 318, Inc. recommends the SonicWall TZ 170 firewall/router for most networks. We feel it’s important to understand some of the differences between using SonicWall’s firewall appliances and the limitations of other, “consumer level” products such as Linksys or D-link routers.
