摘要： A validity time interval for backup data of a data backup operation is determined. The validity time interval is limited, e.g., by an expiration date and/or an activation date. Validity date indicating the validity time interval is stored in non-volatile memory of the tape cartridge, such as a cartridge memory, when the backup data is written to the tape cartridge by the tape drive. Recovery of the backup data from the tape drive is only possible if recovery is performed within the validity time interval, to provide an efficient way to assure tape rotation.
摘要翻译：确定数据备份操作的备份数据的有效时间间隔。有效时间间隔受限于例如截止日期和/或激活日期。当磁带驱动器将备份数据写入磁带盒时，指示有效时间间隔的有效日期存储在磁带盒的非易失性存储器中，例如磁带存储器。只有在有效时间间隔内执行恢复才能从磁带驱动器恢复备份数据，以提供有效的方式来确保磁带旋转。

摘要： A data storage system comprising a server computer and a data storage medium. The server computer includes an interface, such as an iSCSI interface, for communicating with a host computer. In response to receiving data from the host computer, the server computer determines whether or not the host computer has access to a virtual data storage device. If the host computer does not have access to a virtual data storage device, the server computer provides a virtual data storage device for access by the host computer, the virtual data storage device employing at least a portion of the data storage medium such that data stored to the virtual data storage device are stored to the portion of the data storage medium.

摘要： Embodiments of the present disclosure provide apparatuses and methods involving a tape drive apparatus. Briefly described, in architecture, one embodiment of a tape drive apparatus, among others, can be implemented as follows. The tape drive apparatus comprises an interface for coupling at least first and second requesters to the tape drive apparatus, the interface being adapted to receive media control requests from the requestors and identifiers of the requesters; and logic circuitry for generating log entries and writing the log entries to a log. Each log entry indicates at least a type of one of the media control requests and the identifier of the respective requestor, the logic circuitry being adapted for identification of potentially conflicting ones of the media control requests received from different ones of the at least first and second requestors. Other apparatuses and methods are also included.

摘要： Examples may include backup objects for fully provisioned volumes with thin lists of chunk signatures. Examples may generate one or more full lists of chunk signatures for the address space of a fully provisioned volume, compare each chunk signature of the full list to an unused region chunk signature representing a chunk of an unused region of the fully provisioned volume, generate metadata to indicate used regions of the fully provisioned volume, based on the comparisons, and generate from the one or more full lists, one or more thin lists omitting all chunk signatures determined to match the unused region chunk signature.
