Abstract
A method is used in managing file deletions in storage systems. A request to delete a portion of a file of a file system is received. A first indirect block is associated with the portion of the file and includes a set of file system blocks. A second indirect block associated with a replica of the file is identified. The first and second indirect blocks share a subset of the set of file system blocks. The replica of the file represents a state of the file at a particular prior point in time. Metadata of the second indirect block is updated indicating that the subset of the set of file system blocks are no longer shared between the first and second indirect blocks.
