Hey guys I'm not too good with this kind of stuff. How do I set up remote harvesting so I can harvest with the wallet closed? Do I still need my computer on for that? Finally, is POI only important when harvesting? I just want to hold my stake for as long as I can like a savings, I'm not too keen on acquiring more, nor selling off for the foreseeable future. I may use the exchanges with a little just to play around, hoping it's not too pump and dump like most though

. Any help would be appreciated, cheers.
Edit: Also how do I backup my wallet?
