One of the new features in ITScriptNet V3.0c is the ability to automatically archive all data received by the Omni Server. This is a safety feature to ensure that no data is lost in the event that your back-end database server is down when a portable device sends its collected data. The Omni Server will archive all downloaded Collected Data, as well as Images, Signatures, and GPS tracking data.
You can configure whether Archiving is enabled, as well as specify a clean-up time. This causes the OMNI Server to delete archived data older than a threshold you specify, so that data does not accumulate forever.

The ONMI Configuration utility has all of the archiving options.
