摘要： A method and computer program product are provided to ensure a timely secure data erase by determining whether allocating an additional tape drive would improve secure data erase performance by evaluating a quantity of physical volumes to be secure data erased, a maximum queued threshold, an average time to an erasure deadline and a minimum expiration threshold. An additional tape drive is allocated for the secure data erase process when it is determined that allocating an additional tape drive would improve secure data erase performance.

摘要： An apparatus, system, and method are disclosed for archiving log data. In one embodiment, an allocation module allocates a plurality of log logical volumes in a storage pool for storing copies of log instances. The log logical volumes may be hidden from a user. A log module records log data to at least one first log instance in a cache. A copy module transparently copies the at least one first log instance to a first log logical volume of a plurality of log logical volumes in a storage pool when a copy policy is satisfied. The log module further records the log data to at least one second log instance in the cache, overwriting the at least one first log instance. In one embodiment, a selection module selects a second log logical volume of the plurality of log logical volumes to receive the copied at least one second log instance if the first log logical volume satisfies a wrap policy.

摘要： A method and computer program product are provided to ensure a timely secure data erase by determining an erasure deadline for each physical volume of a plurality of physical volumes and calculating a remaining time for each physical volume. The remaining time is calculated for each physical volume by comparing a current date to the erasure deadline of each physical volume respectively. The physical volumes may then be sorted based on the remaining time and the physical volume with a shortest calculated remaining time will be selectively secure data erased.

摘要： A copy export application implemented in a computational device receives a request to perform a copy export operation of data and metadata to a selected tape in a tape library coupled to the computational device. The copy export application copies the data from the computational device to the selected tape. The copy export application determines a medium error on the selected tape while copying the metadata from the computational device to the selected tape, subsequent to completion of the copying of the data from the computational device to the selected tape. The copy export application sends a request to a tape control application to replace the selected tape by a new tape and copy the data from the selected tape to the new tape. The copy export application copies the metadata to the new tape.
