Abstract:
1. A computer-implemented method for securing data of volume mirrors, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising: identifying a set of plexes of a replicated volume; identifying, within the set of plexes, at least one non-trusted plex; intercepting data to be replicated to the non-trusted plex, the data to be replicated to the non-trusted plex originating from an attempt by an application to write the data to the replicated volume; simulating, before encrypting the data to be replicated to the non-trusted plex, successful synchronous replication of the data to the non-trusted plex so that the application is not slowed by encrypting the data to be replicated to the non-trusted plex during the attempt by the application to write the data to the replicated volume; encrypting the data to be replicated to the non-trusted plex; asynchronously replicating the encrypted data to the non-trusted plex; wherein the computer-implemented method avoids the performance of unnecessary decryption operations by:
