Abstract: A computer entity, particularly but not exclusively a headless computer entity, has operating systems stored on a non-volatile data storage device e.g. a hard disk drive, and has a back-up data storage device. Operating system backup's are taken from an uncorrupted copy of an operating system stored in a separate partition on the data storage device to the primary operating system which is actually used to run the device, thereby ensuring that if the primary operating system of the computer entity becomes corrupted either gradually or catastrophically, the back-up copy which is stored on a back-up media is not effected. Under failure conditions of the computer entity, a pristine copy of the operating system can be reloaded from the back-up tape data storage media and the computer entity rebooted from the pristine operating system back-up copy.

Abstract: A headless computer entity having a plurality of disk drives operates to self restore to a known state, upon failure of either a system disk drive containing an operating system of the computer entity, or failure of a data disk drive containing application data. Depending upon whether the system disk and/or the data disk are replaced by a replacement disk, the computer entity configures itself with either deletion of application data on the data disk, or with deletion of application data on both the system disk and the data disk. The computer entity determines whether a new replacement disk has been installed by comparing a signature of the system disk with a signature of the data disk. If a replacement disk is detected, then the digital signatures are set by the computer entity such that the system disk and data disk have a self consistent set of hardware specific digital signatures. Application data is returned to a known good state after deletion.

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.
