There are a few items of manual maintenance you need to do occasionally. Annually is usually sufficient.
Remove old logs from the logs directory (Linux)/opt/beginfinite/retain/Tomcat[version]/logs or (Windows) Program Files/beginfinite/retain/Tomcat[version]/logs
Remove old deletion reports from the archive directory. The file location can be found under Retain Web console | Server Configuration | Storage tab. If it is not under the base storage path, you may need to select Advanced settings and temporarily disable “Derive all file locations from above base path?“
Remove old exports from the exports directory. The file location can be found under Retain Web console | Server Configuration | Storage tab. If it is not under the base storage path, you may need to select Advanced settings and temporarily disable “Derive all file locations from above base path?“
