> The numberToKeep param for snapshots doesn't work anymore. If you set the
> param to '2', only '1' backup is kept.
> In the ReplicationHandler in line 377 snapShooter.validateCreateSnapshot();
> creates an empty directory for the new snapshot. The deleteOldBackups()
> method in Snapshooter which will be executed before the backup is created,
> now sees the two directories an deletes the old one. But this is wrong
> because the empty directory for the new backup should not be considered.
