[rdiff-backup-users] Problems with failed backups and 0.11.4

[Roland Pope]

Hi,

 I am doing some testing with rdiff-backup 0.11.4 between two RedHat 9 boxes
over SSH and I am having some issues trying to kick off another backup after
one failed with the following error:

When I try to start the backup again I get the following error:

Previous backup seems to have failed, regressing destination now.

Any ideas how I can

A) Stop rdiff-backup from trying to regress the failed backup.
B) Deal with the initial error which cause the failure.

Thanks
