desiBackup

Introduction

This product contains wrapper scripts on the HPSSPy package.

Configuring desiBackup

desiBackup configuration is provided by the file etc/desi.json. This file is fully described in the HPSSPy configuration document. Please be sure to read that document before editing the configuration file. If you need additional help with the configuration, please contact the DESI Data Systems mailing list.

Using desiBackup

This package provides the command-line script desiBackup.sh that wrappers the HPSSPy command missing_from_hpss. The backup applies to and is intended for entire top-level directory trees. For example, to perform a backup of spectro/redux/oak1, one first makes sure that the configuration is set up to properly map to an HPSS file (see above), then run:

desiBackup.sh spectro

For additional detail or debugging you can add the -v option. The backup can be tested without damaging anything by using the -t option.

Testing desiBackup

Currently, desiBackup is tested by ensuring that the file etc/desi.json is valid. Specifically this command is run:

python -c 'import json; j = open("etc/desi.json"); data = json.load(j); j.close()'

If the file is valid, this command will produce no output. Invalid files will raise an exception.
