Data arrival by network transfer

  1. change to arsf user on a safe machine
    • ssh arsf@gridmaster2 # (or su - arsf and don't turn your machine off!)
  2. find the exact data path on Ops server
     # go find the path to the data to download
     # these will vary..
    cd /data/Data_2009/
    cd UK
    cd 281-09_GB08-02_Delamere
     # check path
     # returns /data/Data_2009/UK/281-09_GB08-02_Delamere
     # check size isn't crazy big
     # > 150GB and think about a disk transfer
    du -hsc .
  3. create a temporary directory in ~arsf_data/YYYY/flight_data/unpacking/ to download to, e.g.
    DOWNDIR=~/arsf_data/`date +%Y`/flight_data/unpacking/download-`date +%Y%m%d%H%M%S`
    mkdir $DOWNDIR
    cd $DOWNDIR
  4. do the download with rsync. Note there is no trailing / on the PROJECTNAME part of the path below - this is important!
    • rsync -avz . ; date

If something goes wrong after an hour or two, don't delete what you've already downloaded. Instead, repeat the rsync command and it'll pick up where it left off.
