You can use the --remove-meta parameter to remove previously saved checkpoints.

If there are many upstreams, you can also use start-time in conjunction with safe-mode, which is simpler and has a higher priority than the saved checkpoint.

start-time is only available in v6.1

When did you configure this? Binlog log files have size and time thresholds, and they will be deleted if exceeded.
