Electronic Vaulting

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 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 that stores only those files that have been modified since the time of the most recent full or incremental backup. This is also used to mean the process of creating such a backup.
