Thanks for the feedback! Yea think a ZFS redundancy + Backup will do for my application then. From what I am reading here it is less common than I imagined

Yea I have been trying to avoid high power consumption as power is quite expensive here. I think for my case non ECC + ZFS + backup will suffice. Thanks!

From what I understand of it your passwords and all should be save as it also stores them clientsided. So its more like your sync is down. But dont quote me on that
