A script runs daily on astro.suth, and pulls recent data from all the instruments of which it is aware. At the moment, this includes shocnawe, shocndisbelief and SpUpNIC, but we will be adding more instruments as we have the opportunity. We are also configuring a version of this script to run on astro.cape, after the astro.suth script has completed; this will synchronize data between Sutherland and Cape Town. There should then be two back-ups of the data on each instrument.
By default, the script runs from a cron job, but can also be run manually. The script synchronizes data from the last N days, where N is specified by the user. The default value is 30; this should ensure that if data is not copied on some particular day, it will be copied on a later day. If the instrument is unmounted before the scheduled sync time, or data is acquired after the sync but before unmounting, then this might lead to data not being immediately copied for that day. If the machine is off for more than 30 days (as currently configured), then a manual sync should be doneafter the instrument is remounted.
It is possible to specify a specific date to synchronize (-d option), as well as a specific instrument (-i option).
