 When the selected condition is true, then the management policy performs the specified action. For example, if you have defined an action to move a blob from the hot tier to the cool tier if it hasn't been modified for 30 days, then the lifecycle management policy will move the blob 30 days after the last write operation to that blob.
 
 For a blob snapshot or version, the condition that is checked is the number of days since the snapshot or version was created.
