I try to backup my mail directory to a USB disc with
% obnam --log=obnam.log --repository=/media/HD-PCU2/ backup ~/Mail
00h00m00s 1 files; 0 B (0 B/s) setting upERROR: Operation not permitted
The USB disc is mounted with the following options
/dev/sdb1 on /media/HD-PCU2 type vfat (rw,nosuid,nodev,uhelper=udisks,uid=1000,gid=1000, shortname=mixed,dmask=0077,utf8=1,showexec,flush)
The obnam.log contains

Do you have an idea what's the problem with the USB disc? A backup into my home directry works fine.

Obnam currently does not work with FAT filesystems, since it needs the
filesystem to support hardlinks. --liw

This is now fixed in bzr. --liw
