Default value is "no". NUMBER_CLEANUP=boolean Defines whether the number cleanup algorithm should be run for the config. Default value is "no". NUMBER_MIN_AGE=seconds Minimal age for snapshots to be deleted by the number cleanup algorithm. Default value is "1800". NUMBER_LIMIT=number Defines how many snapshots the number cleanup algorithm should keep. The youngest snapshots will be kept. Default value is "50". TIMELINE_CREATE=boolean Defines whether hourly snapshots should be created. Together with the timeline cleanup algorithm this will create a collection of snapshots with more snapshots is the near past and less snapshots in the far past. Default value is "no". TIMELINE_CLEANUP=boolean Defines whether the timeline cleanup algorithm should be run for the config. Default value is "no". TIMELINE_MIN_AGE=seconds Minimal age for snapshots to be deleted by the timeline cleanup algorithm. Default value is "1800".
