Snap shots of the Delft-FEWS database can be archived via the archiveExportModule (exportSnapShot activity).
For snapshots a dataset is generated and stored under the configured area at the memoment of workflow execution. The associated directory structure of the Delft-FEWS export for this type of dataset is as follows:
<archiveRoot>/<yyyy>/<MM>/<areaId/<snapshot>/
Figure 4.9 and Table 4.8 documents the associated elements in the exportSnapShot activity:

Since 2019.02 the archive snapshot export is incremental. A copy of the last exported snapshot is made to use as base for the new export. The modified and new rows are copied. Rows that are no longer in the specified profile or central database are deleted from the copy. The snapshot is compacted afterwards . Whether or not a previous snapshot is used as base, the created snapshot contains the same rows and has the same size.
