According to the disclosure, a unique and novel archiving system that allows the digital shredding of archived data is disclosed. Embodiments of the archiving system include removable disk drives that store data, which 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 such that the removed data cannot be retrieved or deciphered. In alternative embodiments, a protection may be placed on the data required to be kept because the data is associated with a legal suit. This 'legal hold' prevents the data from being digitally shredded. As such, the archiving system can provide a system that can dispose of data on a file-by-file or granular level without physically destroying the media upon which the data is stored.

Methods for control of digital shredding of media

Embodiments of the present disclosure provide a unique and novel archiving system that includes two or more network storage systems, each network storage system including removable hard 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 archiving system accesses, writes, reads, or performs functions on data from one network storage system to another remote network storage system.

Methods for controlling remote archiving systems

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.

Methods and systems for rule-based worm enforcement

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. For example, a modular drive bay maintains a pointer to a memory address in the removable drive memory cannot write data to a memory block that precedes the pointer. Data may only be stored after the pointer in the removable drive. As such, once data is written to the removable drive, the data cannot be overwritten although the removable drive employs random access memory.

Methods for implementation of worm mode on a removable storage system

According to the disclosure, a unique and novel archiving system that provides one or more application layer partitions to archive data is disclosed. Embodiments include an active archive including a fixed storage. The active archive can create application layer partitions that associate the application layer partitions with portions of the fixed storage. Each application layer partition, in embodiments, has a separate set of controls that allow for customized storage of different data within a single archiving system. Further, embodiments of methods for ensuring storage capacity in the active archive and the application layer partitions within the active archive is also disclosed.

Methods for implementation of an active archive in an archiving system and managing the data in the active archive

Embodiments provide systems and methods for storing data on two or more removable disk drives. The two or more removable disk drives are inserted into a modular drive bay having two or more drive ports. Embodiments of the modular drive bay include a switch to redirect operations to a drive port. By arraying the drive ports, the removable disk drives may be replaced without needing to readdress the removable disk drives when new removable disk drives are inserted. Thus, the modular drive bay does not require configuration changes when new removable disk drives are inserted.

Methods for implementation of an array of removable disk drives

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.

Methods for implementation of worm mode on a removable disk drive storage system

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.

Methods for implementation of data formats on a removable disk drive storage system

A multi-city wavelength link architecture is used to distribute spectral bands received on input optical signals among output optical signals. Such an architecture may include an optical wavelength cross connect having multiple input ports, multiple output ports, and a wavelength routing element that selectively routes wavelength components between one optical signal and multiple optical signal. Such an optical wavelength cross connect will generally receive cross-connect-input optical signals at the input ports and transmit cross-connect-output optical signals from the output ports. Methods are used to increase the number of cities that may be accommodated by the architecture without disrupting through traffic between the existing cities.

Multi-city DWDM wavelength link architectures and methods for upgrading

A data storage system for removably storing information is disclosed. The data storage system includes a cartridge receptacle adapted to electrically and mechanically engage a removable data cartridge. The cartridge receptacle includes a second electrical connector and a conductive member. The second electrical connector is adapted to electrically engage a first electrical connector of the removable data cartridge. The conductive member is configured to engage a resistive portion of the removable data cartridge before the first and second electrical connectors engage. The conductive member is coupled to a ground of the cartridge receptacle.

Data cartridge with electrostatic discharge protection

Data are stored on a random-access storage medium. A user set of data is received. The user set of data is mapped to multiple frames. For each frame, error-correction bytes are generated over the data mapped to that frame. In addition, the data mapped to that frame are written to a number of data blocks of that frame and the error-correction bytes generated for that frame are written to a number of error-correction blocks of that frame. At least one of the number of error-correction blocks and the number of data blocks differs among at least some of the frames.
