Data Backup Procedure

This procedure is based on the one outlined by Moo-Young Chun here: https://docs.google.com/document/d/1Nh-vrKHGmwLOPa4Z-0qiD-I4Vg8kxWrzsBcrDyFC9Dc/edit

The IGRINS data is located on 5 different machines:

DCCS - S Detector Control Computer

DCCH - H Detector Control Computer

DCCK - K Detector Control Computer

ICC - Instrument Control Computer

DSC - Data Server Computer

The DCC hard drives are each 1TB, but only 888GB are available for detector readout.

The ICC has a 1TB hard drive, and the DSC has a 250GB fusion drive and two 2TB hard drives.

All of these hard drives are accessible from the ICC once the volumes have been mounted as part of the IGRINS Startup Procedure.

During a trimester files are to be copied from the ICC to the DSC in order to make a duplicate of each file. In addition to the copy saved by each observer, this ensures at least three copies.

At the start of a trimester all files from the previous trimester will be archived.  This is accomplished by:

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 the DSC you need to:
      1. open a safari window
      2. vnc://192.168.2.1 and enter your login information
2.
