For file archiving, a typical policy might instruct the storage system to copy all files from one location to another. Another example might direct the storage system to copy all source files to numerous different locations based on the files' characteristics, age or last access. A policy manager can also apply filters and exclusions. For example, a storage system might search for files that match a certain criteria, move those files to another location, verify the successful copy, and then delete the files from their original location.
Still another example might be to archive files to a certain disk after a particular project wraps up. Policies can also be used to direct data movement after storage system changes or upgrades. For example, an upgrade policy might direct the storage system to save a copy of your data to a temporary location, replace the tape or disk system with another device, then move the temporary data back to the new storage systems. Finally, some policies may assist with random tape or disk testing to verify that data is being properly archived and is retrievable.
Before deleting old data copies, it's important to verify that the new/copied data is properly copied and that it's available to be read. Storage administrators must then worry about secure deletion and see that there is an ongoing unalterable log of all deletions. This ensures that an organization can track data from creation through archiving, movement and destruction.
