Hot Site

A backup site that is a duplicate of original data center with full IT computing infrastructure and replicated data. It is the most expensive business continuity solution. A configuration in which a backup facility is maintained in constant working order, with a full complement of servers, workstations, and communications links ready to assume primary operations responsibilities. A fully operational offsite data processing facility equipped with both hardware and system software to be used in the event of disaster.

A backup site that contains the IT infrastructure (hardwarewise, sometimes application), but not the data. A middle ground between hot sites and cold sites for disaster recovery specialists. A warm site always contains the equipment and data circuits necessary to rapidly establish operations but does not typically contain copies of the client’s data. A warm site is similar to a hot site; however, it is not fully equipped with all necessary hardware needed for recovery.

An inexpensive type of backup site with no IT infrastructure (e. g. , computing and network hardware) in place. An IS backup facility that has the necessary electrical and physical components of a computer facility, but does not have the computer equipment in place. The site is ready to receive the necessary replacement computer equipment in the event the users have to move from their main computing location to the alternative computer facility.

A storage scenario in which database backups are transferred to a remote site in a bulk transfer fashion. The remote location may be a dedicated alternative recovery site (such as a hot site) or simply an offsite location managed within the company or by a contractor for the purpose of maintaining backup data.

Mirror image backups (also referred to as bitstream backups) involve the backup of all areas of a computer hard disk drive or another type of storage media (e. g. , Zip disks, floppy disks, Jazz disks, etc. ). Such mirror image backups exactly replicate all sectors on a given storage device. Thus, all files and ambient data storage areas are copied. Such backups are sometimes referred to as “evidencegrade” backups and they differ substantially from standard file backups and network server backups. The making of a mirror image backup is simple in theory, but the accuracy of the backup must meet evidence standards. Accuracy is essential and to guarantee accuracy, mirror image backup programs typically rely on mathematical CRC computations in the validation process. These mathematical validation processes compare the original source data with the restored data. When computer evidence is involved, accuracy is extremely important, and the making of a mirror image backup is typically described as the preservation of the “electronic crime scene. ”
