Wild shot here, but are you sure your disks are healthy? They might have errors that could throw off truenas

I see, thanks for clearing that up. In my situation, keeping a few terabytes on 3 hard drives and backing up to a reliable cloud copy (not sync, as you mentioned) is good enough for me. Optical media is impractical with the amount of data, and tape drives far too expensive for just a few TBs.

Whatever you decide to do, please implement 3-2-1 backups (3 backups: 2 backups offline, 1 offsite). This will cost more obviously, but family data is important and its safety shouldn’t be skimped on.

Setting up let’s encrypt auto cert renewal with ACME. Also looking to setup some monitoring service, basic stuff like CPU, memory usage etc. If anyone has recommendations that have an android app available, that would be awesome.

I always wondered if people still make quirky Lego cities like the old days
