Patent number: 8171244Abstract: Embodiments provide systems and methods for maintaining immutable data in an archiving system using random access memory. To ensure data is immutable, novel pointers are maintained in the hardware/firmware of the drive ports and on the removable disk drives. For example, a hardware/firmware in a modular drive bay maintains a pointer to a memory address in the removable disk drive memory that cannot write to a memory block that precedes the pointer. Data may only be stored after the pointer in the removable disk drive. As such, once data is written to the removable disk drive, the data cannot be overwritten although the removable disk drive employs random access memory.Type: GrantFiled: February 1, 2008Date of Patent: May 1, 2012Assignee: Imation Corp.Inventors: Matthew D. Bondurant, Mark Payne, S. Christopher Alaimo

Patent number: 8156292Abstract: An archiving system including one or more removable disk drives embedded in removable disk cartridges, referred to simply as removable disk drives. The removable disk drives allow for expandability and replacement such that the archiving system need not be duplicated to add new or more storage capacity. In embodiments, the removable disk drives store metadata that contain information about the data stored on the removable disk drive. The metadata allows the system to retrieve the correct data from the random access memory and establishes controls on the data stored on the removable disk drive. In embodiments, the metadata is stored in two locations, such that, if the metadata in one location is corrupted, the second copy of the metadata may be retrieved.Type: GrantFiled: January 4, 2011Date of Patent: April 10, 2012Assignee: Tandberg Data Holdings S.A.R.L.Inventors: Matthew D.

Publication number: 20120079198Abstract: Systems and methods for commonality factoring for storing data on removable storage media that may allow for highly compressed data to be stored efficiently on portable memory devices. The methods include breaking data into unique chunks and calculating identifiers, e.g., hash identifiers, based on the unique chunks. Redundant chunks can be identified by comparing identifiers of other chunks to the identifiers of unique chunks. When a redundant chunk is identified, a reference to the existing unique chunk is generated such that the chunk can be reconstituted in relation to other chunks in order to recreate the original data. One or more of the unique chunks, the identifiers, and/or the references may be stored on the portable memory device. Hardware and/or software for the chunking and/or hashing functions can reside in a host computer, a removable storage device or cartridge, and/or a removable cartridge holder.Type: ApplicationFiled: September 23, 2011Publication date: March 29, 2012Inventors: Matthew D.

Publication number: 20120036319Abstract: Systems and methods for commonality factoring for storing data on removable storage media are described. The systems and methods allow for highly compressed data, e.g., data compressed using archiving or backup methods including de-duplication, to be stored in an efficient manner on portable memory devices such as removable storage cartridges. The methods include breaking data, e.g., data files for backup, into unique chunks and calculating identifiers, e.g., hash identifiers, based on the unique chunks. Redundant chunks can be identified by calculating identifiers and comparing identifiers of other chunks to the identifiers of unique chunks previously calculated. When a redundant chunk is identified, a reference to the existing unique chunk is generated such that the chunk can be reconstituted in relation to other chunks in order to recreate the original data. The method further includes storing one or more of the unique chunks, the identifiers and/or the references on the removable storage medium.Type: ApplicationFiled: October 17, 2011Publication date: February 9, 2012Inventor: Matthew D.

Publication number: 20120036280Abstract: Embodiments provide unique and novel systems and methods for deleting data on removable disk drives. In embodiments, the removable disk drives store data that may be erased such that the data is considered destroyed but that allows the removable disk drive to be reused. The archiving system can determine which data should be erased. Then, the data is digitally shredded on sector boundaries of the removable disk drives such that the reclaimed memory cannot be read to decipher the erased data. In alternative embodiments, data is written across sector boundaries such that two or more files may occupy a single sector. A journal area, in embodiments, allows for copying the data in a sector with two or more files, digitally shredding the sectors in the removable disk drive, and rewriting the data that was not to be digitally shredded to the original location of the data.Type: ApplicationFiled: August 22, 2011Publication date: February 9, 2012Inventors: Matthew D.

Publication number: 20100318501Abstract: Systems and methods for storing and accessing data on a removable media having a changeable data set and an immutable data set. In one embodiment, a system can comprise a removable media storage system adapted to determine whether a host system running one or more applications is configured to enforce Write Once Read Many (WORM) policies. The host system can be communicatively coupled with the removable media storage system and configured to execute instructions causing the host system to determine whether to allow or deny a request to access data on the removable media. The host system can use rules to determine if an access request is to access data of a changeable data set or a immutable data set. If the request is to access data of the changeable data set, access is allowed. If the request is to access data of the immutable data set, reads are allowed, as well as writes of new data. Access requests to rename, delete, and/or write to existing data of the immutable data set are denied.Type: ApplicationFiled: May 25, 2010Publication date: December 16, 2010Applicant: ProStor Systems, Inc.Inventors: S.
