    keyword=Target Data Daily Backup for Ay

    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 coda raw data.

    1. Almost all Target data for experiment is acquired 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 10^6.

    2. Everyday 8PM, adaq@spin:/cygdrive/c/AyeD (main work/data directory) and adaq@spin:C:\HappyValentine\data (Spin flip data) will be copied to a none deleting image site /adaql4/work1/PolHe3Targ/SpinBackUp . This process will take ~1hour

    3. Then the image site will be tar into a zip package and send to adaql1:/stage1/halla/e05102/raw/. Then it will be copied to Jlab central tape as permanent storage together with raw coda data. A typical size of the package is ~0.5GB.

    4. The backup could be cached out by

    jcache /mss/halla/e05102/e05102_PolHe3Target_.tar.gz
