20100293137 | METHOD AND SYSTEM FOR JOURNALING DATA UPDATES IN A DISTRIBUTED FILE SYSTEM - An exemplary embodiment of the present invention provides a method of processing a file system transaction in a distributed file system. The method includes receiving a transaction request from a computer, wherein the transaction request includes file data to be stored and a first segment identifier that determines a destination of the file data. The method also includes generating a first distributed journal record corresponding to the file data. The method also includes generating a first file operation request based, at least in part, on the transaction request. The method also includes sending the first file operation request to a first segment server corresponding to the first segment identifier, wherein the first segment server generates a second distributed journal record corresponding to the file data on a memory device associated with the first segment server. | 11-18-2010 |

20140214773 | RECONSTRUCTING A STATE OF A FILE SYSTEM USING A PRESERVED SNAPSHOT - A technique includes receiving a request to restore a state of a file system. The request defines a rollback period, which extends from a restoration time that is specified by the request to a time at which the request was made. The technique includes reconstructing a state of the file system in response to a query using a preserved snapshot of the file system. The reconstruction including reconstructing the state at an arbitrary query time based at least in part on a dynamically inheritable attribute of an entity stored on the file system and the rollback period. | 07-31-2014 |
