With the explosive growth of data in business today, problems arise due to the shrinking backup windows, the need for larger repositories for backup data, longer on-site retention needs for recovery and the perceived problems associated with backup up directly to tape.  When disk becomes the primary storage medium for this data, new issues arise; the cost associated with the expansion of disk array’s in the face of ever growing data requirements, the loss of the removability of media with disk, limited functionality and manageability between virtual tape libraries (VTLs) and physical tape libraries (PTLs), disk access frequency and usage. Data de-duplication arose primarily to overcome the problems associated with the need for larger repositories for backup data and longer on-site retention needs for recovery.
