>Meanwhile Linux only supports 64 KB

Yes, absolutely true, thanks for the addition:

-Linux max 64kb (some filesystems just 4k)

-HFS+ max 128kb, But MacOS theoretically supports up to 64MB!

-FreeBSD max 64MB with UFS2 or ZFS

-Windows 65536 bytes with NTFS

So from BSD (MacOS) to BSD should/could work.

Truly messy stuff :)

So build your own NAS on BSD+ZFS and use rsync w/xattr's? Not a bad solution theoretically...

[nix23 → mrkstu]

Keep in mind that your mounted NFS needs to support xattrs too :)

mount -t nfs -o user_xattr

I just found out that ~only? the Solaris/illumOS NFS-server supports that, and the Linux Client since Kernel 5.9

With all that information..i honestly would just make a dump of my FS and backup the dump, terrible i know.

This is the advantage of the "newfangled" backup tools which don't just copy files from A to B and can do (but not always do!) a much better job at a) not caring about your backup destination's file system b) not losing data that's more complicated than "name and contents".
