Re: [rdiff-backup-users] Assertion Error, Fatal Error: Lost connection to the remote system. Rdiff-Backup v1.2.8-1 on Ubuntu 8.10 Intrepid Ibex

[Josh Nisly]

Although the error message should be better, I believe that you are 
calling rdiff-backup incorrectly. Depending on what you are trying to 
do, you should either run:

rdiff-backup --test-server address@hidden

or 

/usr/bin/rdiff-backup address@hidden::/var/exports/ /var/backups/fileserver/

In other words, --test-server is only for testing whether rdiff-backup is 
functioning correct at the remote host. Since it appears that you are wanting 
to actually run a backup, I believe that you need to remove the --test-server 
parameter.
