Method For Extending Life Span Of Online Documents Stored In An Enterprise Content Management System

Online documents stored in an Enterprise Content Management (ECM) system are typically stored on commodity magnetic spinning hard drives. Certain types of ECM systems keep documents as archives where the documents are preserved for many years or indefinitely. The documents are read many times but never written due to restrictions for changing the documents. The magnetic field strength of data stored on hard drives is known to degrade at a fixed slow pace which can be approximately 1% per year. After a long time, accumulated weakness of the documents can increase the likelihood of data being read incorrectly which is termed as data corruption.

Disclosed is a method for extending life span of online documents stored in an Enterprise Content Management (ECM) system. The method provides a background process in the ECM system that scans all files looking for the files which are exceeding a set threshold. For example, the physical media age of each file can be checked. For instance, 7 years can be considered as a typical threshold value. When a file with 7 years of age is found, a polishing process is used to re-generate the file. The polishing process includes an ability to re-write bytes of the file at a block level to make re-writing

of all the bytes of the file possible. The polishing process does not take any additional space on the disk to re-write all the bytes of the file. The re-writing of blocks causes

field strength for bits of the fi...
