摘要： An incremental backup system that performs the following (not necessarily in the following order): (i) making a plurality of time-ordered journal entries; (ii) determining that a corruption condition exists; (iii) responsive to a corruption condition, constructing a first incremental mirror data set that reflects a backup data set and all journal entries up to a first corrupted journal entry which is the earliest in time journal entry, of the plurality of journal entries, that is a corrupted journal entry; (iv) responsive to a corruption condition, constructing a second incremental mirror data set that reflects the backup data set and all journal entries up to the first corrupted journal entry; and (v) checking for corruption in the first and second incremental mirror data sets to determine the latest uncorrupted version of the data set.

摘要： Various embodiments for monitoring safety by a processor. A presence of a living thing is detected inside an enclosed environment to be monitored. The enclosed environment is capable of motion. The presence of the living thing is monitored in combination with at least one environmental factor in the enclosed environment. If the at least one environmental factor exceeds a predetermined threshold, an alert notification to indicate a current status of the environmental factor is provided to a user.

摘要： Disclosed aspects include management of a set of blocks in a storage system. A set of write requests is initiated to the set of blocks. In response to the set of write requests, a set of expiration metadata for the set of blocks is established. Based on the set of expiration metadata, an expiration event is detected. In response to detecting the expiration event, an expiration operation on the set of blocks is processed.

摘要： Provided are a computer program product, system, and method for selective write control in accordance with the present description. In one aspect, a write operation which is associated with a read operation, may be selectively discarded if write operations have been disabled and if the write operation is directed to update a designated write operation acceptance area such as metadata associated with the target data set, for example. As a result, the read operation may be permitted to proceed and will not fail because the associated write operation was discarded rather than attempting to commit the write operation to the designated write operation acceptance area, thereby avoiding an error condition for a storage unit such as a volume, in which write operations have been disabled. Accordingly, applications which seek to perform read operations may be permitted to access data stored on such a volume. Other aspects are described.

摘要： Provided are a computer program product, system, and method for data unit classification in accordance with one embodiment of the present description, in which in response to a data processing command, a storage controller classifies data units of a storage unit as either allocated to a data set or as unallocated to any data set. If allocated to a data set, the storage controller can further classify data set-allocated data units as either containing client data or metadata or as empty. In accordance with one aspect of the present description, the storage controller may bypass data processing of the data units which have not been allocated to any data set or otherwise do not contain client data or metadata. Other aspects of data unit classification in accordance with the present description are described.

摘要： A method, according to one embodiment, includes receiving a request for a hypervisor to run a virtual machine, determining using a processor whether the virtual machine is authorized to run using a data structure having metadata about properties of the virtual machine, determining using a processor whether the hypervisor is authorized to run the virtual machine using a digital signature of the data structure, receiving a decryption key from a key authority when it is determined that the virtual machine is authorized to be run and it is determined that the hypervisor is authorized to run the virtual machine, unlocking and/or decrypting the virtual machine using the decryption key, and running the virtual machine on a computer system. Other systems, methods, and computer program products are described in additional embodiments.

摘要： A method for releasing storage space in a space-efficient volume is disclosed. In one embodiment, such a method includes maintaining, for a space-efficient volume, a bitmap comprising a bit for each track in the space-efficient volume. A host system indicates whether a track is one of used and unused by marking the corresponding bit in the bitmap. A storage controller reads the bitmap and frees tracks from the space-efficient volume that the bitmap indicates are unused. In certain embodiments, the bitmap is stored on the space-efficient volume. For example, the bitmap may be appended to a volume table of contents (VTOC) stored on the space-efficient volume. A corresponding system and computer program product are also disclosed.

摘要： An apparatus for providing traffic alerts includes a distance module, analysis module, transmission module, and signaling module. The distance module measures the distance between a vehicle and an object in front of the vehicle. The analysis decides whether to signal a presence of the object that comprises determining that the measured distance is equal to or less than a threshold distance. The transmission module transmits an alert in response to the analysis module deciding to signal a presence of the object. The signaling module transmits a visual signal to one or more vehicles behind the vehicle in response to receiving the alert from the transmission module. The visual signal has one or more characteristics.
