Hmmm, I thought any 2 TB limit was gone meanwhile, but then your argumentation has some merit.
Some hints that it might be gone nonetheless:
| JXFS 64 bit file system | | With AmigaOS 4.x a new file system has been introduced called JXFS. It is | a totally new 64 bit file system that supports partitions up to 16 TB in | size. It is a modern journalling file system, which means that it reduces | data loss if data writes to the disk are interrupted. It is the fastest | and most reliable file system ever created for AmigaOS.

Well I asked AmigaOS 4 developers about this issue as well. Lets see what they say about 2 TB limits.
But nonetheless, I think, Linux should refuse to use a partition that is clearly out of bound.
Scrubbing the one backup BTRFS that has 360 GiB of data was okay. Also the fsck´s went well. Well the volume group is not completely full so some space on the end of the disk is not yet used by it.
I am recreating all my backups on BTRFS volumes now - except maybe the one thats on the BTRFS volume already and scrubs okay.
