Hi Weal, In general, it is not recommended to use Solr as a primary storage so it is better to store your data somewhere else. That will allow you o reindex if needed and also allow you to not store some field in index and make it more efficient. When it comes to your original question, it seems that backup/restore feature should be enough for you. If it is single node and static index, you can even do it manually - simply backup index folder, and when need to restore on some other place, create collection/core with same config, replace index folder with one that you backed up and reload collection/core.
