Abstract
Journal event consolidation extracts events occurring between two predetermined point in time on data volume, categorizes the events into categories of events, and consolidates the events in the categories of events.
Claims20
A method for consolidating journal events, comprising:
- categorizing a plurality of events operating on data during a predetermined period into one or more category of events;
- extracting a pattern of events from the one or more category of events, wherein the pattern of events comprises two or more truncate events, each truncate event indicating a file system filter driver operating on the data has truncated a file to shrink or expand the file;
- and
- removing redundancy in the pattern of events by consolidating the pattern of events into a consolidated pattern of events based on one or more predetermined rules associated with the extracted pattern of events, wherein consolidating the pattern of events comprises removing from the pattern of events all truncate events except for last truncate event and creating a union of all write events in the pattern of events to indicate a full range of data effected by all the write events in the pattern of events.

A computer readable storage medium storing a program of instructions executable by a machine to perform a method of consolidating journal events, comprising:
- categorizing a plurality of events operating on data volume into one or more category of events;
- extracting a pattern of events from the one or more category of events, wherein the pattern of events comprises two or more truncate events, each truncate event indicating a file system filter driver operating on the data has truncated a file to shrink or expand the file;
- and
- removing redundancy in the pattern of events by consolidating the pattern of events into a consolidated pattern based on a predetermined rule associated with the pattern of events, wherein consolidating the pattern of events comprises removing from the pattern of events all truncate events except for last truncate event and creating a union of all write events in the pattern of events to indicate a full range of data effected by all the write events in the pattern of events.

A method for consolidating journal events, comprising:
- categorizing a plurality of events operating on data volume into one or more category of events;
- extracting a pattern of events from the one or more category of events;
- and
- removing redundancy in the pattern of events by consolidating the pattern of events into a consolidated pattern by removing a rename event indicating a file or directory name was changed, in response to detecting a create event indicating the file or directory was created as first event in the pattern of events and a close event indicating the file or directory was closed as last event in the pattern of events.
