Abstract
A method is described. The method includes queuing an entry in a queue that identifies an inode that has been changed in an active storage system. The entry further describes a time in the future. The method includes processing the entry upon the time in the future being reached. The processing of the entry includes comparing respective content values maintained for different regions of the inode within the active storage system and a replicate storage system. The method further includes comparing content of those of the regions having different content values as between the active storage system and the replicate storage system. The method further includes updating those regions in the replicate storage system to reflect those regions within the active storage system based on the comparing, and, updating the respective content values of those regions in the replicate storage system.
