Directory Structure
The /opt/iccr/data directory contains a comma separted value (CSV) formattted file: iota-event.csv.
The iota-event.csv file contains a record of the events that the ICCR executed when controlling and configuring the IOTA IRI process.
For example

The /opt/iccr/conf directory contains the iccr.properties file and the ICCR pki files that enable secure HTTPS transport.
The /opt/iccr/logs directory is the location where the ICCR log file iccr.log is written to.
The /opt/iccr/lib directory is the location containing the single ICCR uber-JAR file that is executed when the iccr-ctl script is used to start ICCR.
The /opt/iccr/bin directory contains scripts used by ICCR.
The /opt/iccr/tmp directory is used by ICCR, when downloading new versions of the IRI. Newly downloaded IRI files are first written to this temporary directory before being copied to the final /opt/iota.
The /opt/iccr/bak directory contains backup copies of previous versions of the IOTA IRI file.
After downloading a new version of the IOTA IRI file, ICCR will copy the previous version into /opt/iccr/bak to provide for a disaster recovery possibility. ICCR will not automatically restore any previous IRI version, it only makes copies of previous versions to allow the system administrator to manually execute a previous version if needed.
The /opt/iccr/download directory contains the newly downloaded copy of the IOTA IRI file, while ICCR is downloading and installing a new version of the IOTA IRI. The newly downloaded IRI will be written into this directory, then copied into the configured IOTA directory.
