Abstract
A periodic checkpoint method for a file system replication source. The method comprises generating a first checkpoint at a first time on a file system replication source and identifying a set of data objects from the replication source that have been modified during a time period between the first time and a subsequent second time. A periodic checkpoint is then generated at the second time on the file system replication source by using the set of data objects.
