Abstract
A technique for replicating a file from a source data storage system (source) to a destination data storage system (destination) includes receiving, by the destination from the source, (i) file data for multiple logical extents of the file and (ii) respective tiering metadata for those logical extents. The destination selects, based on the tiering metadata, one or more storage tiers available on the destination. The destination updates a local replica of the file by placing the logical extents on the selected tier or tiers.
