hi all, I want to buy a nas as some kind of backup and/or storage device. I am really struggeling when it comes to backup and you can never be sure.... its always the same question in my head. what happens if the backup device is broken and do I need a backup of a backup? I am addicted to make everything 110% sure however, it should be between 1 and 2 tb and not too expensive. are there any recommendations for cheap but reliable devices? How about a solid state drive? are there bigger ones that are not as expensive as if they were made of gold? thanks for your input!
