Field Description
The access time is the minimum number of days that must pass since the le was last
accessed before the le can be data reduced. This value must be in the range of 5 to 365,
inclusive. By default, this value is 30 days. The status of the lter is listed as File
filters…disabled if the ignore-lters option was set through the CLI. If the status is
File filters…disabled, any lters that have been congured through the GUI (or
CLI) for Access Time or Modify Time have been disabled and all les are candidates for
data reduction. Specifying the ignore-filters ag 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.
Modify time lter Minimum time since the last modify time before les on this container qualify for data
reduction.
