Abstract: Disclosed is a method of restoring a client device following failure of the client device, the client being connectable to a network comprising a server device. The method comprises saving to the server device a configuration state of the client device, the saved configuration state comprising client network interface configuration information, and a file of the client device. The method further comprises, following failure of the client computer, recording on a medium bootable on the client device program instructions for configuring the client device according to the saved configuration state, booting the client device from the bootable medium, configuring a network interface of the client device in accordance with the program instructions and the saved configuration state and restoring the file to the client device by copying over the network.

Abstract: A method for securing access to a data medium comprises listing at least one unique identifier of media that a data transfer element is allowed to access in memory storage of the data transfer element, accessing only media having at least one of the listed unique identifiers in media cartridge memory with the data transfer element, and writing a unique identifier associated with the data transfer element to the cartridge memory of the selected medium with the data transfer element in response to no library assigned unique identifier being present in the cartridge memory of the selected medium.

Abstract: A method for securing access to a data medium comprises recording a unique identification number assigned to each medium in at least a portion of a data library, and commanding at least one selected data transfer element in said library to only accept media having particular ones of said identification numbers.

Abstract: A storage area network associated data library partitioning system comprises a plurality of storage slot elements adapted to store data storage media, at least one set of at least one of the slots is assigned to one partition of a plurality of partitions, and a plurality of data transfer elements that are adapted to receive the media and transfer data to and from the media, each of at least one set of at least one of the data transfer elements is assigned to one of the partitions, at least one data transfer element of each of the partitions hosts a logical element designation of a virtual controller for each of the partitions, the virtual controllers restricting movement of the media to between the set of slots and the set of data transfer elements assigned to a same of the partitions.

Abstract: An automated storage apparatus having a data transfer device transfers data to and from data storage units. A robotic device moves the data storage units. An area holds the data storage units for which no data is presently required to be transferred thereto or therefrom. A reference data storage unit is in the holding area. In response to information indicating an excessive error level in transferring data between one data transfer device and a respective data storage unit: one data transfer device inserted in the data storage unit is removed; and a reference unit is inserted in the data transfer device for a reference transfer operation.

Abstract: A hand-held portable reader and labeling device for interrogating data storage cartridges of the type containing an in-built memory chip having information stored describing details of data contained on the data storage medium is disclosed. The reader-labeling device comprises a processor, random access memory, printer, display, keypad, operating system, transponder, receiver and battery power supply. By scrolling a menu display, key parameters describing a data cartridge can be accessed quickly and efficiently without the need to access the data storage medium itself. A cartridge media specific label may be rapidly printed for attachment to a data storage cartridge.

Abstract: A library system having a reader and labeling device (200) for interrogating data storage cartridges of the type containing an in-built memory chip having information stored describing details of data contained on the data storage medium is disclosed. The reader-labeling device comprises a processor, random access memory, printer, display, keypad, operating system, transponder, receiver and battery power supply. Key parameters describing a data cartridge can be accessed quickly and efficiently without the need to access the data storage medium itself. A cartridge media specific label may be rapidly printed for attachment to a data storage cartridge. The reader-labeling device may be incorporated into an automatic library (201) accessible by a robotic arm (202), wherein the user may quickly read summary information describing a data storage cartridge or its contents from information stored on a memory attached to the cartridge by use of the reader-labeling device externally controlled.

Abstract: Clients are connected via a LAN to backup apparatus including hard and tape drives, respectively primary and secondary backups. Each client schedules backup operations on a time basis since last backup, the amount of information generated since last backup, etc. Prior to a backup, each client sends to the backup apparatus a request including information representing the files to be backed up. The backup apparatus receives backup requests from the clients and accepts or rejects backup requests based on backup and network loading. The backup apparatus eliminates redundant files and indicates to the clients, prior to the file back up, that some files requested to be backed up are already stored and are not to be sent. The backup apparatus enables a client to restore any of its ‘lost’ data by copying it directly from the disk, without the need for backup administrator assistance.

Abstract: A tape drive operates as a bootable device for a PC. In a first mode, the drive operates as a normal tape drive. In a second mode, the drive emulates a bootable CD-ROM drive. Application software for backing up and restoring computer system data causes the PC running the software to generate a bootable image comprising an operating system including the PC hardware configuration, and data recovery application software. The bootable image can re-build the PC in response to a disaster, such as hard disk corruption or system destruction. The bootable image is stored on tape in front of a file system backup data set. In the second mode, the tape drive boots the PC and restores the operating system and application software. When loaded, the application software switches the tape drive into the first operation mode and restores the file system backup data set to the PC.

Abstract: A backup system includes backup application software operating on a host computer, which is configurable to store data to be backed up to a backup apparatus. The system is configurable to schedule and enact a pre-backup check, prior to running the actual scheduled backup job so that any faults which have developed since the initial configuration can be remedied. The pre-backup check preferably occurs on a daily basis prior to every scheduled backup job.
