Storing data on technologies that match their desired access requirements can significantly reduce cost. Maintaining static, unstructured files on fast RAID systems, or even slow RAID systems, can be uneconomical.
To increase storage optimization, organizations should identify what types of data they are creating and storing.
Some files that are created can be archived at the start of their life, for example scanned documents or patient images. Other files become static after a period of time, this time period is usually different for each file type.
With data life-cycle management, the desired access location of the file should vary over time. Another term for this is ‘tiered storage’, where policies are preset to facilitate the migration of files through the hierarchy of storage as they age.
QStar Network Migrator software, (QNM) a policy-based data migration software, can define data and, based on policies set, automatically move, copy or migrate it to more appropriate storage technologies within the hierarchy. An organization can move static files (up to 80%) from primary storage into the archive, greatly improving storage optimization, as well as copy data to remote or offsite storage, for disaster protection purposes.
Migration leaves behind a “stub” file which redirects the read request to the new file location. In conjunction with QStar Archive Manager, QNM allows files to be actively accessed no matter what technology they are located on within the archive.
