Filesystem Operation Bookmarking for Any Point in Time Replication

Abstract

An agent executing on a processor at a data production site detects filesystem events and creates a list of bookmarks describing the filesystem events in user-understandable strings. Each bookmark is associated with metadata about the filesystem event that includes a timestamp and a point-in-time (PiT) snapshot of the filesystem at the time of occurrence of the event. The bookmarks and associated metadata are transferred to a recovery site and the bookmark set is recorded in storage. The storage can be searched for bookmarks in the set that reference the filename of a file of interest, and the file recovered and replicated using an associated PiT.

Dependencies are inferred from the claim text.
