I handle this by actually backing up to "backupname.incomplete". Once
the backup is complete I then rename it to
"backupname.yyyy-mm-dd.HH-MM-SS". That way all of the backups with
date+time stamps in the name are completed backups and if a backup
fails repeatedly that will not count multiple times against the number
of backups I intend to keep.
