By default, the value for both times is 30 days. • Modify Time The modify time is the minimum number of days that must pass since the file was last modified before the file is eligible for data reduction.

NOTE: The status of the filter is listed as File filters....disabled if the ignore-filters option was set through the CLI. If the status is File filters...disabled, any filters that have been configured through the GUI (or CLI) for Access Time or Modify Time have been disabled and all files are candidates for data reduction. Specifying the ignorefilters flag enables data reduction on a container with archive data without waiting for the minimum Access Time/ Modify Time data-reduction policy. Dell recommends that you not use this setting on containers with live data. That is, you should use this setting only on containers with archive data.
