Be ready to deal with a backup plan. Consumer services like Backblaze don’t work with Linux.
I have opted into backing my data up to a local network NAS machine which in-turn backs all of its data up to a StorJ backed s3:// compatible endpoint which is very inexpensive.
I moved over to TabloTV about 8 or 9 years ago. I got tied of fixing stuff when I would update something and Tablo just worked on the Roku without much fuss.
I’m still happy with and love the Tablo, but it’s no better than MythTV was, just easier to maintain.
