Data Protection and Recovery Handbook |
What is Data Recovery?Many people equate data recovery with restoring data from a tape backup,or use the term "data recovery" interchangeably with "disaster recovery" as in recovering from a major disaster such as a flood, fire or bombing attack. These meanings are quite true in the general sense and "data recovery" is usually one step of the "disaster recovery" process.However, the term "data recovery" has a very specific meaning in the computer industry – "The act of obtaining usable data from downed computers and backups." Data recovery cases can be divided into two broad categories: |
Common RecoveriesInvolve floppies and hard drives that are usually from single-user personal computers.Complex RecoveriesInvolve hard drives, RAID arrays, tape and optical media or corrupted databases and file systems usually from multi-user, business systems. Data storage at the high end has become a very complex field. In the case of these complex situations data recovery can be seen as "troubleshooting data storage."Whether common or complex, each data recovery case is unique and the process can be very resource-intensive and exceedingly technical. |
