So this is confirmed, your file system is ext3 with block size 1 KB, and this limits file size to 16 GB.
You have to do your backup to another file system with a bigger block size. Or stream it to a tape.
--
Or recreate the /home file system with a bigger block size.
This would delete all your existing data, so you need a full backup before you do it!
Nowerdays mkfs should default to a 4 KB block size, and file size limit is 64 GB.
Or define explicit options as shown by
Code:
man mkfs.ext3
