1. Copy ICC files to DSC, UT external HD, and KASI external HD. 
   1. Each system is setup with a storage tree that identifies the initial hard drive and the trimester of the files. (HD>DCCS_4> 2014T2>files sorted by local date of observation)
   2. To copy the files while maintaining the files dates and copying every subdirectory
      1. cd to the target directory        cd /Volumes/HD/OBSDATA/2014T2
         
      2. use this format.          cp -apv /IGRINS/obsdata/201409* .
   3. For To copy to the DSC you need to:
   4. open a safari window
   vnc://192.168.2.1 and enter your login informationto use scp or drag and drop in Finder.
2. Copy DCC files to external hard drive.
   1. cd to the target directory        cd /Volumes/HD/2014T2
   2. use this format.          cp -apv /IGRINS/obsdata/201409* .
      
   3. or drag and drop

In order to avoid filling hard drives they must be cleaned after the copies have been made. 

The DCC appear to save every fowler read as a separate file, producing 32 16.8MB files for each nod position. For a 12 hour night this is roughly 25GB of storage, and for a 60 night trimester this is 1.5TB of data on a 1TB HD.

So, it is necessary to copy and clean the DCC hard drives more than once per trimester.

The ICC only has space issues if the observer saves every image. The slit view camera produces ~30GB of files each night. We can avoid filling this hard drive by turning off the autosave function.

The DSC should be able to store a year of ICC copied files at a time.

When the ICC and DSC hard drives are full, we will delete the oldest trimester stored. The DCC hard drives will be cleared every other month.
