Abstract
A method and system for efficiently importing/exporting a removable storage volume having a number of data files from a first virtual storage system to a second virtual storage system. The method includes writing a table of contents to the end of the removable storage volume in the first virtual storage system. The table of contents uniquely identifies the data files residing in the removable storage volume. Next, the removable storage volume is transferred to the second virtual storage system. Upon receipt of the removable storage volume, the second virtual storage system updates a database in the second virtual storage system utilizing the information contained in the table of contents without having to read each of the data files in the removable storage volume. In a related embodiment, for each of the data file in the removable storage volume, the table of contents includes a filename, starting record on the removable storage volume and number of records in the data file.
