Thank you for recommendation! I think I looked at Unraid and other options like FreeNAS and Proxmox etc, but from what I understand - the main value add of Unraid is presenting multiple HDDs as a single volume and with a single data drive (1) it does not make much sense (2) I specifically wanted to be able to stick the drive into another computer, and mount its ext3 file system and go, that came in handy few times. As for the amount of data - I went full Marie Kondo on my old datasets and now my backup set is well under 2TB.
