1. A method for responding to an access request from a user, the method comprising:
receiving, by a target storage system (TSS) and from a user, an access request to access an exposed file system entity (EFSE), the access request is associated with an EFSE external identifier (EEID);
applying a logically reversible function on the EEID and on a replication stream identifier (RSID) to provide a TSS internal EFSE identifier (TID); wherein the EFSE and the EEID were sent by a source storage system to the TSS in association with a replication stream that is identified by the RSID, wherein the EFSE and the EEID were exposed, by a storage system other than the TSS, to the user, during a mount process;
accessing the EFSE using the TID; and
wherein the TID uniquely identifies the EFSE within the TSS.
