3 Points of Data Recovery

Doing data backup is easy.  Considering the needs for data recovery is where many go wrong.  There are 3 points of data recovery that must be considered when putting together a proper Backup and Disaster Recovery plan.

1. Recovery of a File – Very simple and straight forward, you must be able to recover data files.  Can you recover deleted files from every location people save files?  Most files reside on the server or in a document management system.  Are people saving these documents on their workstations while they edit them?  What happens if Microsoft Word crashes?  I am sure that the file server is backed up, but is it backed up often enough?  Daily backups taken over night are typically not sufficient in most modern networks.

2. Recovery of a Server – Many business owners take comfort in that fact their server is being backed up without ever considering what recovering the server really means.  How long will it take to get a replacement server?  Will the same type of server be available? How do people work while waiting for the hardware?  Once you have the replacement server, how long will it take to restore it to service?  With many backup solutions, restoring requires the server OS and applications to be reinstalled before the data is restored.  It adds another level of complexity (and time) when recovering to dissimilar computer hardware.

3. Recovery of a Site– Unfortunately, disasters do happen.  Here in Texas the media has been marking the ten year anniversary of the tornado that ripped through downtown Fort Worth destroying buildings and ravaging businesses.  We have also been seeing all the coverage of earthquakes.  And let’s not forget about fires.  A recent study discovered that, of companies experiencing a “major loss” of computer records, 43 percent never reopened, 51 percent closed within two years of the loss, and a mere 6 percent survived over the long-term.  Having a plan and being able to recover quickly can greatly improve the chances of the business surviving.

A Complete Solution that addresses all of these points –
A good backup system should allow for quick and flexible restores that allows for recovery of files, folders, partitions, mailboxes/messages, databases/tables using a quick and intuitive process.  A 15-minute incremental based backup allows restores to be done from any point in time, allowing for multiple versions of files, folders, messages/mailboxes, database/tables to be restored.

If any of your servers fail, a good data backup solution will include virtualization technology embedded in the Network Attached Storage (NAS) that allows customer servers and applications to be restored and rebooted in less than 30 minutes in most cases.  As you may sometimes wait several days in order to receive replacement servers from vendors, your NAS can have your business up and running.  The NAS multitasks so that, even while functioning as a virtual server, it can continue to back up data from other devices plugged into the NAS.  This technology thus allows you to remain in business without any significant loss of data backup, server functionality, or application downtime.  In case of a complete server failure the solution should support a bare metal restore to new hardware which has a different configuration, hardware and drivers as compared to the failed server.

Transmitting data to a remote site is another key component of a worthy Backup and Disaster Recovery Plan. It guarantees that, in case of physical damage to the client’s network or NAS, or even regional disaster, the data is safe. Encryption is required in transmitting data between the NAS and the remote sites, because it greatly reduces the risk of data loss incidents that plague magnetic tape and prevents man-in-the-middle attacks during transmission.  Of course a key consideration of off-site backup is the amount of time it could take to restore data over the Internet.   Solutions that offer both transmission as well as emergency delivery of a new device with the most recent image are doubly effective.

In summary, the most important aspects of Backup and Disaster Recovery are to first, have a specific plan, second have a well thought out and comprehensive plan that matches the requirements of your business and lastly, to consistently manage and test your BDR solution.   In an age of document management, EMR, paperless office, HIPAA, HITECH, Sarbanes Oxley, eDiscovery, etc., a reliable Backup and Disaster Recovery solution are paramount to the longevity of your business.

Data Backup and Recovery: 7 Questions to Answer

The statistics are gloomy: 50 percent of companies that loose their data for 10 days or more file for bankruptcy within that same time period.

Ninety-three percent file for bankruptcy within one year.

Now that I’ve got your attention, now’s the time to start preparing for disaster, before you become another statistic! The first step is

1. Who will be responsible for the plan and who will perform the actual recovery of the data? The time for pointing fingers is not when disaster strikes. The person who creates the plan and the person who performs the actual recovery may be the same—or not. Determine who’s responsible for what early in the plan to avoid confusion and misunderstandings.

2. How important is your data? Data varies in importance, helping you determine how and when it should be backed up. For instance, critical data, like a customer database, will likely require a plan that’s more elaborate, with more frequent and redundant backup sets that go back several backup periods. Less important information, such as daily user files, may simply need routine backups so you can recover the information when needed. Sift through your data and identify your most important and least important information.

3. What kind of information does your data contain? Data can contain everything from mundane, everyday information to highly sensitive and mission-critical information. Additionally, information that’s not very important to you might be important to someone else. Identifying the type of information your data contains will help you determine how secure your backup system needs to be, as well as when and how frequently your data should be backed up.

4. How frequently does your data change? The answer to this question determines how frequently you should back up your data. Information that changes daily should be backed up daily. Information that changes every few days should—at the very least—be backed up every few days. And so on.

5. When is the best time to schedule backups? Over the weekend? During the evening hours? In the morning? Backing up data generally takes less time when system use is low. Unfortunately, you may not be able to schedule backups to occur at these times. Carefully consider the best time and day to back up your information, keeping in mind that automated technology makes this easier while minimizing administrative time.

6. How quickly will you need to recover data? Apply the old adage here: time is money. Some businesses may function relatively well for a day or two without access to their systems and data stores. Others may crumble in a matter of hours. If you fall into the latter category and need to get access to critical systems immediately, create a plan that lets you do this. Prioritize which systems you need first, second and so on, and make sure your recovery solution delivers.

7. Should you store backed-up information off-site? The answer for most businesses: yes. This is especially important if you operate in an area prone to natural disasters such as tornadoes or hurricanes. In addition to storing your tapes or disks off-site, make sure you store copies of any software you need to re-establish operations, and that multiple people have the keys or access code for that location.

Avoid saying, “If only …”

No one anticipates a disaster. But we can plan for it. Today’s backup and recovery technology makes protecting your critical business information and systems easier and more affordable than ever. So stop making excuses. Start planning. Information is one of your business’ most important assets. Protect it.
