Abstract
Techniques are provided for rebuilding a destination file system as part of a resync operation. A file system of a first node may be replicated to a second node as a destination file system. The file system may include clone files that were created as clones of parent files. The clone files may have been created in a storage efficient manner where a clone file refers to data of a parent file, instead physically storing duplicate instances of the parent data of the parent file. The techniques provided herein are capable of replicating the clone files to the second node while preserve the storage efficiency of the clone files during a resync operation that rebuilds the destination file system after recovering from a failure of the second node.
