• Eliminate the short and medium storage classes.

• After the initial 4 months period, the expiration status of a run is determined by the access pattern of its files. 
  • This will be enforced by the constant monitoring of the file systems to determine which files were accessed and when. We will be also tracking if the files were actually analyzed or just "touched" to dodge the policy. 
  • Analyzing the data extends the lifetime of the access accessed data by 1 month from the access date.
  • Data restored from tape will stay on disk for 1 month, i.e. it's treated as a file access.
