Minimal backup should include mongodb database at /var/lib/StarRiver Pro/data/db and all configuration files at /var/lib/StarRiver Pro/conf
If you need to keep files uploaded by users such as media files, backup /var/lib/StarRiver Pro/data/storage
If a variety of historical records need to be backed up, backup the directory of Elasticsearch data at /var/lib/StarRiver Pro/data/es. The data in this directory will accumulate by time. If you need to backup, it is recommended to use incremental backup.
