I am planning a 8 hdd unit, currently thinking of qnap. As a second option (most probable) I will chose two 6 hdd units: one for the main storage, the second for the online incremental backups of the first one.
I just want to know if someone has some experiences and if have found some flows/bugs.

Regards
