Data backup

The following programs are used to manage data archiving:

• xray1_archive_yesterday is to be run on the machine x1a.nsls.bnl.gov by invoking it in a manner like

   xray1_archive_yesterday x1aos 20050512
  

  (If you don't specify a date, it will do yesterday by default). This will make a zip file x1aos_20050512.zip and transfer it to xray1. This script is automatically run as a cronjob each morning for each of the microscopes x1aos, x1ais and x1aic.

• On request a PHP script looks up all existing zip files and offers them (sorted by date) for download on our website

• test_archive_zipfiles can be used to generate a shell script for testing all the zip files in a specified date range in the archive. Run the program with no arguments to get help on how to use it.
