[rdiff-backup-users] recovering from interrupted backups

[Jeffrey Forman]

i've been in the situation where i'm backing up a machine to another and
the backup gets cut in the middle. usually since the boxes are across
the continent from each other, the network has a hiccup. since my backup
jobs are cron'd, after that first interrupted backup, it fails to backup
subsequent backups. i have to completely rm -rf the directory on the
machine receiving the backup and start over again.

what can i do on either end so that backups recover from interrupted
backups?
