Well I'm so impressed with it (especially after trying the Scanner too) that I've bought the 2 app deal after only 2 days trial
Using this on my N54L Microserver which is purely used as my media store/Plex server + torrents at home. I'm finding it much easier to understand/use than FlexRAID Pooling I purchased last year. For this server its more about max storage space than redundancy.
I only really need Folder Duplication for critical frequently changed/added files (photos/Home Movies), as I backup to another Microserver on a schedule, so no big deal getting my large Movie files back
