Planning for recovery is a requirement in businesses of all sizes. In implementing an operational plan that ensures that both data and applications can be recovered, IT personnel are generally confronted with several challenges:
Business requirements are not the only mandates that may be driving the evolution of your recovery plan. Various industry- specific regulatory mandates, including Sarbanes-Oxley, HIPAA, and SEC, specify requirements for data retention and recoverability. In meeting these requirements, businesses have to deal with a variety of risks to data including inadvertently deleted files or records (operator error), viruses or hackers that can cause data corruption or deletion, and natural disasters that may put much more than just your data at risk. Distributed or branch offices may also have ease of use requirements that may not apply to larger, more centralized businesses.
Do you have a plan that meets your recovery requirements to your satisfaction across these areas?
Issues with Legacy Recovery Technologies
If you are like most businesses, you are using some form of data protection today – probably tape-based backup. Periodically, someone shuts applications down to perform a backup to tape. Depending on the volume of data that is being copied, this may take several hours and requires manual intervention to set up the backup job, run it, confirm that it occurred, and then return the application to operation. The backup copy may be kept locally in case data needs to be recovered in the near term, and eventually (after several weeks) it may be moved to an offsite location for archival storage purposes. The reason to make and keep copies of your data is so that, in the event of some sort of event or catastrophe that deletes or destroys data, you have a clean copy safely tucked away to use for recovery purposes.
Tape is used for backup and archive because it is very inexpensive, but it is an old technology that has been available almost since the dawn of computing. There are several issues with tape-based backup:
Transporting tapes to offsite facilities for archival purposes also has inherent risks. Widely publicized tape losses during physical transport (by truck) have hit large companies like Bank of America, Citigroup Inc., ChoicePoint, Inc. and LexisNexis and resulted in the theft of hundreds of thousands of company records. Replication of data across secure IP-based networks is a much faster, easier, and safer way to transport data to offsite locations for archival storage purposes. If you are driven by either business or regulatory requirements to deploy a disaster recovery solution, a pure tape-based data protection strategy can subject you to undue risk.
