    keyword=Target Data is daily backed up to central Tape

    A daily backup routine has been setup to copy target data to adaqfs. Meanwhile a snap shot package will be permanently stored in JASMine along with e06010 coda raw data.

    1. Almost all Target data for experiment is aquired on target computer spin.jlab.org. Typical data are small text file like NMR and EPR records. However the number of file are on the order of 1GB, 10^6 files.

    2. Everyday 8PM, adaq@spin:/cygdrive/c/HappyValentine (main work/data directory) will be copied to a none deleting image site /adaql4/work1/PolHe3Targ/SpinBackUp . This process will take ~2hour

    3. Then the image site will be tar into a zip package and send to adaql1:/stage1/halla/e06010/raw/. Then it will be copied to Jlab central tape as permanent storage together with raw coda data. The typical size of the package is ~0.5GB.
