Disaster recovery
Disaster Recovery is the process, policies and procedures of restoring operations critical to the resumption of business, including regaining access to data (records, hardware, software, etc.), communications (incoming, outgoing, toll-free, fax, etc.), workspace, and other business processes after a natural or man made disaster.
To increase the opportunity for a successful recovery of valuable records, a well-established and thoroughly tested disaster recovery plan must be developed.
With the rise of information technology and the reliance on business-critical information the importance of protecting irreplaceable data has become a business priority in recent years. Most companies rely on their computer systems as critical infrastructure in their business. As a result, most companies are aware that they need to backup their digital information to limit data loss and to aid data recovery. Most large companies spend between 2% and 4% of their IT budget on disaster recovery planning; this is intended to avoid larger losses. Of companies that had a major loss of computerized data, 43% never reopen, 51% close within two years, and only 6% will survive long-term.
The following is a list of the most common strategies for data protection.
-
Backups made to tape and sent off-site at regular intervals (preferably daily)
-
Backups made to disk on-site and automatically copied to off-site disk, or made directly to off-site disk
-
Replication of data to an off-site location, which overcomes the need to restore the data. This generally makes use of Storage Area Network (SAN) technology
-
High availability systems which keep both the data and system replicated off-site, enabling continuous access to systems and data
In addition to preparing for the need to recover systems, organizations must also implement precautionary measures with an objective of preventing a disaster situation in the first place. These may include some of the following:
-
Local mirrors of systems and/or data and use of disk protection technology such as RAID
-
Surge Protectors — to minimize the effect of power surges on delicate electronic equipment
-
Uninterruptible Power Supply (UPS) and/or Backup Generator to keep systems going in the event of a power failure
-
Fire Preventions — more alarms, accessible fire extinguishers
-
Anti-virus software and other security measures
