Mirrored site

An alternate site that contains the same information as the original. Mirror sites are set up for backup and disaster recovery as well to balance the traffic load for numerous download requests. Such “download mirrors” are often placed in different locations throughout the Internet.

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. ”
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.
The fee a recovery site vendor usually charges when the customer notifies them that a disaster has occurred and the recovery site is required. The fee is implemented to discourage false disaster notifications.
A type of disaster recovery test, often referred to as a “table-top exercise,” in which members of the disaster recovery team gather in a large conference room and role-play a disaster scenario.
A detailed process for recovering information or an IT system in the event of a catastrophic disaster such as a fire or flood. A document that guides the recovery efforts necessary to restore your business to normal operations as quickly as possible. Provides for the continuity of system operations after a disaster.
