Description
A ‘Repack’ is the process of moving or copying data from one tape cartridge to one or multiple others. Such a process may be needed for various reasons, such as transferring data to more compact media, creating additional copies, and recovering data from faulty media. At CERN the CTA software manages the data transfer itself, but more steps are needed in order to complete the full repack process for each tape cartridge.
In this presentation we will give an overview of the repack process at CERN and present ATRESYS, the tool developed to automate most of it. By using ATRESYS we are able to queue batches of hundreds of repacks and have them run their course without micro-management by operators. The tool will soon be available as free software as part of the CTA operator tools.
