Bill,

Based on your traceback, it looks like your sshfs setup is broken.  
Either sshfs has changed, or your kernel, or the server from which you  
are mounting the fs ...

The traceback says that rdiff-backup received "Operation not  
supported" (EOPNOTSUPP) when it tried to do:

mkdir "/media/Ext Drive/backups/rdiff-backup-moenchweiler-etc/rdiff- 
backup-data/rdiff-backup.tmp.0"

if you can do that, as the user which rdiff-backup runs as, then there  
*could* be a bug in rdiff-backup, but based on what you have posted, I  
would say there is definitely a bug in sshfs or your setup. Given that  
it got an error while executing that simple command, I'm sure you  
agree that the problem is related to your sshfs setup. :-)


If you cannot determine where the bug is in this setup, I would  
recommend that you *not* use sshfs. Instead, you should install rdiff- 
backup on the destination system, and then run the backup as `rdiff- 
backup /my/files address@hidden::/my/backup`. It is much more reliable,  
you will get better performance due to the rsync algorithm, and rdiff- 
backup will intelligently avoid problematic filesystem issues.
