A method for managing lost content change requests (CCRs), the method includes (i) maintaining, by compute entities of a second storage system (SSS), states of executions of multiple CCRs of multiple categories and of multiple SSS reception times; (ii) receiving, from a first storage system (FSS), at a failure indication reception time (FIRT), a failure indication that is indicative of a certain category of the multiple categories. The certain category is associated with a failure of the FSS to receive a response, from the SSS, to a certain CCR of the certain category, that was presumably sent from the FSS to the SSS; (iii) determining, based on states of executions that are related at least to the certain category, when the SSS has completed to execute all CCRs of at least the certain category that were received by the SSS up to the FIRT; and (iv) transmitting, by the SSS, a SSS completion indication that indicates that the SSS has completed to execute all tasks that were received by the SSS up to the FIRT.

Lost write responses

A method for network group based access control, the method may include (i) receiving a request to access content stored in a storage system, the request is associated with a user and a network group that is suggested to include the user; (ii) generating a user key based on an identifier of the user and the network group; (iii) determining, based in part on the user key, whether the user is a current user of the network group, and (iv) declining the request when the user is not the current user of the network group. The determining may include determining that the user is not a current user of the network group when a user finding timestamp of the user precedes a network group finding timestamp of the network group.
