Changing the Amount of Retained Data

The ingestor stores data in image segment files, as described in the Overview.

SSEC sets a default retention window of three days of data for MTSAT HRIT visible and IR imagery. Approximately 12 GB of disk space is needed for each day's worth of retained data.

Perform the following procedure if you want to change the amount of data retained in your ingestor.

1. Edit the file /data/opt/etc/rc.MTSAT-HRIT

2. Change the value of the variable named DAYS= from its default setting of 3 to the number of days of data you want to make available.

3. Stop and start the ingest software.
