Wait, aren’t seed boxes just VMs that run on the infrastructure of some internet hoster that doesn’t give a crap about the users utilizing it for torrenting? But AFAIK on most seed boxes the user needs to configure the VMs themselves to some degree. So it acts as some beefed up proxy server to torrent stuff without you compromising your own ip address + you have access to high bandwidths and some tb of storage to store your downloaded stuff
I have a cheap 2 bay synology NAS that acts solely as a backup server for my main NAS in an offsite location as well as a USB drive locally.
Backups run every night with duplicacy
I exclude media files (movies, TV shows,…) from my backup routine due to the sheer amounts of data accumulated over time and the fact that most of it can be re-aquired using public sources in case disaster recovery is needed
