Abstract: The described embodiments set forth techniques for preserving clone relationships between files at a computing device. In particular, the techniques involve identifying clone relationships between files in conjunction with performing operations on the files where it can be beneficial to preserve the clone relationships. The operations can include, for example, preserving clone relationships between files that are being copied from a source storage device (that supports file cloning) to a destination storage device that supports file cloning. Additionally, the operations can include preserving clone relationships when backing up and restoring files between a source storage device (that supports file cloning) and a destination storage device that does not support file cloning. In this manner, the various benefits afforded by the clone relationships between files can be retained even as the files are propagated to destination storage devices that may or may not support file cloning.

Abstract: A method is provided that includes initiating a copy operation to copy a set of files from a source location on a first storage device to a destination location on a second storage device. Metadata is stored on the second storage device in association with the destination location to include the source location on the first storage device and an indication that the copy operation has been initiated. The metadata is updated with identifying information of files from the set of files successfully copied from the source location to the destination location during the copy operation. After an interruption in the copy operation, the copy operation is resumed based on the metadata identifying the source location of the set of files and the identified files successfully copied from the source location to the destination location prior to the interruption.
