• Eliminate the short and medium storage classes.
• Switch from an experiment wide policy, where all files from one experiment stay on disk for a fixed duration of time after the end of the experiment, to a run wide policy where the expiration status of the files is determined by the access pattern of the files of a specific run. 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. 
  • Igor: no need in this statement as this has always been like this. Perhaps we should just say/remind that: "...for raw and translated data all files associated with a run and stored within a particular folder would be a subject for the Policy..."
• Analyzing the data extends the lifetime of the access data by 1 month from the access date.
• Data restored from tape will stay on disk for 1 month.
• Change the lifetime for raw and scratch data disks to 4 months. (For raw data the cleanup will affect all files, i.e. all streams and chunks, which make up one run, rather than individual files.)
• Eliminate the /ftc folder (data currently under ftc will be moved to scratch and the scratch policy will apply).
• Rename the usr folder as usrdaq.
• Rename the res folder as results.
• Increase the quota of the results folder to 2TB.
• Igor: What should we say about files restored from tape? Should we assume a different expiration term for them?
• Igor: What should we say about NERSC?
