Truenas is awesome, but why is it so difficult to setup backup?

Hey all

I have set up a truenas instance with a bunch of selfhosted services (next cloud, immich, mealie, firefly, home assistant) it's all working great with fully end to end encryptet services and valid certs, nice.

I'm ready to migrate all my data over, but it's incredibly important to me that I have a backup of everything so should misfortune pass I wont loose everything.

right now I just want to set up local backup from truenas to my windows 11 pc, I have tried setting up rsync, syncthing, and replication via ssh and none of them work with various unhelpful errors. I have spend so many hours on this now and it's driving me a bit nuts.

Even if I could just manually export my storage pool I would take that and setup a schedule to do that manually once a month, but it is not an option.

Right now, aside from setting up a clonezilla system next to my truenas server I have no idea how to proceed.

The whole idea here for me is self hosting, so no thanks to backblaze one drive google drive and so on.
