[rdiff-backup-users] Hi + Backup Failing

[Alain Russell]

Hi,

I'm relatively new to rdiff-backup, been using it for a few weeks now.
I've run into a problem where my backups are failing (seemingly on the  
same directory/file) - the log of what happens is below.

Fatal Error: Lost connection to the remote system

If I do --check-destination-dir everything seems ok and I can re-run  
the backup manually, but it will fail again. Backups have been going  
fine until this happened, they are triggered from the backup server  
and pull data from live server.  If I try and backup just this  
directory it appears to backup ok to a new test location so guessing  
its something to do with the local index file, but have no idea about  
Python ..

Both servers are running Mac OS X - rdiff-backup 1.2.8.

Let me know if this is an easy fix, or point me in the right direction.
Thanks !
