摘要:
A method for selectively controlling reutilization of space in a virtual tape system (VTS) having a buffer and a multiple volume tape cartridge includes transferring data volume files to the VTS. The buffer transfers the data making up these files as virtual tape volumes (VTVs) to different locations of the cartridge for storage. A file is selectively designated for the VTS to delete from storage after a date included with the file has elapsed by deleting the VTVs corresponding to the file from the cartridge to reuse space of the cartridge. The method includes detecting if a file transferred as VTVs to the cartridge has been designated for deletion. The VTS is prohibited from deleting the file after the date has elapsed if the file was not designated for deletion and is allowed to delete the file after the date has elapsed if the file was not designated for deletion.
