A technique for use in performing snap imaging of a plurality of data objects and associated metadata involves placing the plurality of data objects in a consistent state. While the data objects are in a consistent state, a copy is created of the metadata associated with the plurality of data objects. The data objects are then taken out of the consistent state. The temperature value associated with one or more of the data objects is/are compared with a threshold value. A copy is created of at least some of the data objects for which the associated temperature value exceeds the threshold value.
