Patent number: 8417673Abstract: Provided are a method, system, and program for processing a request to write to a source file in a storage system. A determination is made as to whether a retention rule is provided for the source file. In response to determining that one retention rule is provided for the source file, a versioned file name is generated, wherein a versioned file comprises the source file at a point-in-time. A command is transmitted to a file system to copy the source file data to a versioned file having the generated versioned file name and the generated versioned file name is added to a retention index file. The retention index file is processed to determine whether to purge versioned files according to the retention rule provided for the source file.Type: GrantFiled: October 7, 2003Date of Patent: April 9, 2013Assignee: International Business Machines CorporationInventors: Christopher John Stakutis, Kevin Michael Stearns

Patent number: 7761424Abstract: Provided are techniques for transferring data. It is determined whether an indicators map is to be associated with a source file that is being opened, wherein the indicators map indicates which source blocks of the source file have been updated since last being transferred to a target file. In response to determining that an indicators map is to be associated with the source file, it is determined whether the indicators map exists. In response to determining that the indicators map exists, it is determined whether the indicators map is to be trusted based on a last modified time and a last source file size stored in the indicators map and the source file. In response to determining that the indicators map is to be trusted, the indicators map is initialized. Then, in response to receiving a write for the source file, the indicators map is updated to indicate which portion of the source file has been modified.Type: GrantFiled: August 10, 2006Date of Patent: July 20, 2010Assignee: International Business Machines CorporationInventors: Hong Li, Christopher John Stakutis

Patent number: 7624134Abstract: Provided are a method, system, and article of manufacture for enabling access to remote storage for use with a backup program. Access is enabled to remote storage offered by an Internet Service on a remote server over the Internet. Indication is maintained of files on a source drive in a backup set to store on the remote storage that have a real-time backup status. Te backup set is stored on the remote storage. A modification to a file on the source drive is detected and a determination is made from the indication whether the file being modified is indicated as having the real-time backup status. The modification is transferred to the file to the backup set at the remote storage in response to determining that the file being modified is indicated as having the real time status.Type: GrantFiled: June 12, 2006Date of Patent: November 24, 2009Assignee: International Business Machines CorporationInventors: Christopher John Stakutis, Kevin Michael Stearns

Patent number: 7506116Abstract: Provided are a method, system and program for maintaining and using information on updates to a data group after a logical copy is made of the data group. A first logical copy of a data group in a storage at a first point-in-time is established. The first logical copy maintains data to reconstruct the data group as of the first point-in time after the data group has been updated following the first-point-in time. Indication is made of regions of the data group updated at the storage after establishing the first logical copy. A second logical copy of the data group in the storage at a second point-in-time is established. The second logical copy maintains data to reconstruct the data group as of the second point-in time after the data group has been updated following the second point-in time. The indicated regions of the data group updated between the first and second points-in-time are saved in a change list.Type: GrantFiled: July 19, 2005Date of Patent: March 17, 2009Assignee: International Business Machines CorporationInventors: William Robert Haselton, Christopher John Stakutis, Kevin Michael Stearns

Publication number: 20080294860Abstract: Provided are a method, system, and program for replicating a file. A file is copied to a target storage file system stored as a base file. A reference file comprising the copied file is generated at a local storage. An update is applied to the file at the local storage. A delta file is generated indicating differences between the updated file at the local storage and the reference file. A file system command is used to transmit the delta file to the target storage file system store to store in a directory of the target storage file system, wherein the file in the local storage is replicated at the target storage by a combination of the base file and the delta file.Type: ApplicationFiled: May 30, 2008Publication date: November 27, 2008Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Christopher John Stakutis, Erik Dean Wilkinson, Hong Li

Patent number: 7188127Abstract: Provided are a method, system, and program that processes a file request to operate on a target file that is directed to a file system. A determination is made as to whether a rule specifies a file attribute satisfied by the target file. In response to determining that the target file satisfies the file attribute of the determined rule, a determination is made as to whether a condition specified by the determined rule is satisfied. In response to determining that the condition is satisfied, an action specified by the determined rule is performed. The file request is forwarded to the file system to execute if the rule does not inhibit the file request.Type: GrantFiled: October 7, 2003Date of Patent: March 6, 2007Assignee: International Business Machines CorporationInventors: Christopher John Stakutis, William Robert Haselton
