Patent number: 9910736Abstract: According to embodiments described herein, a backup server maintains backup data for a set of data, which includes data for a first block and a second block. Backup data for the first and second block include backup data for a plurality of versions of the first and second block. A distinct watermark is stored for each version of the first block and each version of the second block. In response to a request to perform a restoration operation on the set of data, a particular version of the first block and a particular version of the second block are selected to use in the restoration operation by comparing a restoration target with the watermarks of the version of the first block and second block. The selected version of the first block has a different watermark than the selected version of the second block.Type: GrantFiled: December 31, 2014Date of Patent: March 6, 2018Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Steven Wertheimer, Muthu Olagappan, Raymond Guzman, William Fisher, Beldalker Anand, Sriram Nagaraja Rao, Chris Plakyda, Debjyoti Roy, Senad Dizdar

Patent number: 8949367Abstract: Techniques for cooperative storage management are described. According to embodiments described herein, a storage server stores backup data for a plurality of client systems, including a first client system and one or more other client systems. The storage server receives a request from the first client system to store new backup data. In response to the request from the first client system, the storage server determines which backup data to delete to make space for the new backup data based, at least in part, on retention duration goals associated with the one or more other client systems. The retention duration goals indicate that the client desires to be able to recover data at least as old as a specified age. The storage server may also determine which backup data to delete based, at least in part, on respective minimum space parameter values for the other client systems.Type: GrantFiled: October 31, 2011Date of Patent: February 3, 2015Assignee: Oracle International CorporationInventors: Steven Wertheimer, Muthu Olagappan, Raymond Guzman, William Fisher, Anand Beldalker, Venky Nagaraja Rao, Chris Plakyda, Debjyoti Roy, Senad Dizdar
