Well, on linux I’d use systemd’s resolved which would listen on localhost:53 (it would also point resolv.conf there) and then set resolved’s uplink server to your custom port. I don’t have the exact config in mind but it seems to support custom uplink ports(“expects IPv4 or IPv6 address specifications of DNS servers […] optionally take a port number separated with “:”[…]”)

Edit: found this: https://en.opensuse.org/Network_Management_With_Systemd

Just set the DNS server to localhost:1053 for the nas?

Especially since they don’t talk about how they secure the local data

They don’t because they don’t

All the data you import is indexed in a SQLite database and stored on disk organized by date, without obfuscation or anything complicated.

Probably because this is still in early alpha and “the schema is still changing”.

How does mergefs compare to btrfs and bcachefs in using multiple partitions?

Drives connected to usb have an unstable connection in my experience, this is very annoying and gets worse with hubs.

RAIDs reduce the time a system is offline and reduce data loss, if a drive fails and you can afford to wait for the new disk and the backup to restore, and have regular backups that ensure no important data gets lost (though remember the data added between backups may be lost) then you don’t need a RAID.

I don’t use RAIDs cause if my disk fails then I can stomach the 2-4 days it takes to buy a new one and restore the backup

Very important: use S.M.A.R.T and a filesystem with checksums to make sure you’re not backing up corrupted data and know to get a new one

For encryption at rest you may want to look at clevis and tang, though you need a server in your home network for this to work. The client (with clevis) then decrypts the disk at boot if it can reach the server (tang). The server can’t decrypt the data without the client secret and the client can’t decrypt it without the server public key.

Don’t know what your server could be though, maybe a router with custom firmware?

You should also look into cloud storage/rclone, that way you can automate your backups more and reduce the need for manual intervention.

I use rclone and restic to automatically backup my servers daily which takes a few seconds most of the time due to them being incremental backups.

It doesn’t though? IANAL but as far as I can tell you can fork, modify and redistribute it as long as you provide the source code to your users.
