LANSA Repository Definitions (supplied as DC@DTALIB). The frequency with which you backup these libraries will depend on the level of development activity. You may choose to backup the production system more often if you are frequently updating help text, for example. If you move a new application into production, you should back it up immediately. |

LANSA Application Data Files
The application data files, in which end users add, change and delete records, should be backed up daily as a regular housekeeping task as part of your site's security strategy. Failure to backup these files daily could lead to serious or total loss of your business data.
