摘要： Predicting whether a file migration will be executed successfully or not. A file storage apparatus in a high-order tier generates a migration task list that records scheduled time periods of migration execution and a total file size of files which are targets to be migrated, and transfers the generated migration task list to a file storage apparatus in a low-order tier; and the file storage apparatus in the low-order tier generates, based on the migration task list, a migration overlap table that records, for each unit time, whether the execution of a migration is scheduled or not, and a remaining file size table that records a predicted value of a data transfer amount for each unit time and a predicted value of a remaining file size for each unit time; and if the predicted value in the last scheduled time period, from among the predicted value of the remaining file size for each unit time which is recorded in the remaining file size table, is equal to or less than 0, it is predicted that the migration will be executed successfully; and if the predicted value in the last scheduled time period is more than 0, it is predicted that the execution of the migration will fail.

摘要： A file, for which writing has been reserved, in a file-sharing system can be efficiently read. A check-in file agent is provided in a computer that executes check-in of a file as the file-write reserving processing, a file manager is provided in a file-sharing computer, and a check-out file agent is provided in a computer that executes check-out of a file as the file reading processing. Upon request for check-in of a file, the check-in file agent divides the file into divided files and generates metadata that indicates the order of division of the file, and transmits them to the file-sharing computer for storage therein. Upon request for check-out of the file, the check-out file agent receives the metadata from the file-sharing computer, and based on the metadata, sequentially receives the divided files to generate a file to be checked out.

摘要： Time required for a file server to determine files to be migrated from a first storage region to a second storage region is reduced. A file service system coupled to the storage system for providing a first storage region and a second storage region stores identifiers of files that have been accessed by a client, in accessed file identifier information and determines the files to be migrated from the first storage region to the second storage region based on metadata of the files stored in the first storage region and the accessed file identifier information.

摘要： When a deletion request to delete a file system is made and a retention period of the file system to be deleted has not expired, the retention period end date and time is displayed at high speed. A CPU 11 gives a retention period attribute to each file of a file system 16 and manages the furthest future retention period end date and time, from among the retention periods of the files, as a retention period end date and time of the file system. If a deletion request to delete the file system 16 is made and the retention period end date and time of the file system 16 is future time ahead of the current time when the deletion request is made, processing for deleting the file system 16 is stopped and the retention period end date and time of the file system 16 is displayed on a screen 235.

摘要： To improve performance of a de-duplication process carried out by a storage system. When receiving a write request from a client, the storage system carries out a first de-duplication process, and thereafter carries out a second de-duplication process at an appropriate time. In the first de-duplication process, a determination is made as to whether a write target data item overlaps with any of stored data items of a part of a stored data item group, which is a user data item group stored in a storage device, and the write target data item is prevented from being stored in the storage device, when a result of the determination is positive. In the second de-duplication process, a determination is made as to whether a target stored data item, which is not finished with an evaluation of whether or not it overlaps with the stored data item in the first de-duplication process, overlaps with another stored data item, and the target stored data item or the same data item overlapping with the target stored data item is deleted from the storage device, when a result of the determination is positive.
