====== Periodic Data Integrity Check (PDIC) ======

Last revision: 2020-10-07 

From v4.1.4.3 onward, the automatic Periodic Data Integrity Check (PDIC) feature is able to provide clients with maximum security and integrity of backup data. The latest enhancement includes a check for data, i.e. files and/or folders, that exists in the index files, but the physical files do not actually exist in the backup destinations.

===== Key Features ===== 

  * Identify and remove outdated entries in the index file for files and folders which do not physically exist in backup destinations
  * Identify and remove index files > 90 days old in backup destination
  * Update storage statistics for data area and retention area usage

===== Process of PDIC =====
