Recover Archive from Disaster

When the archive is down and the data and softeware on jop83_1 are lost, this is the procedure to recover.

• login as archive on jop83.
• Create dir /jop83_1/archive (mostly done by Klaas).
• Step into /jop83_1/archive
• cvs -d :ext:jive_cc@jop83.nfra.nl:/export/home/jive_cvs/PERL_PHP co archive
• mv archive scripts
• cp -r scripts/evngraphics .
• mkdir /jop83_1/archive/util
• cd /jop83_1/archive/util
• cvs -d :ext:jive_cc@jop83.nfra.nl:/export/home/jive_cvs/PERL_PHP co cfitsio
• cd /jop83_1/archive/scripts/avo
• mkdir plots
• chmod 0777 plots

• login as archive
• mkdir /jop83_1/archive/exp
• cd /jop83_1/archive/exp

• Now the data can be restored from the mirrordisk in Westerbork:
  scp -rp trantor:exp/* .

  Or the data can be restored from tape:

• restore2archive.pl, E.g.: restore2archive.pl -f archtape23 -d /jop83_1/archive/exp
  restore2archive.pl

  • -f tapeName
  • -d destination directory
  • -b beginlabel If no beginlabel, the whole tape will be restored.
  • -e endlabel If no endlabel, endlabel = beginlabel
  • -t test program without use of tape device.
  • If a latest version of the experiment is on a higher label
    or on a next tape, the current label will be skipped and the
    position of the latest version will be mentioned.
    

• When destination /jop83_1/archive/exp is almost full, continue in /jop83_2/archive/exp

  Create in jop83_1/archive/exp softlinks to each experiment directory in /jop83_2/archive/exp

• cd /jop83_2/archive/exp.
• run script: /jop83_1/archive/scripts/util/newlink.pl
  The links will be created.

Crontab jobs:

• cd /jop83_1/archive/scripts/util
• crontab crontab.archive
• su jops
• crontab crontab.jops
