Application data sets created on CA Vtape Virtual Volumes are stored in files that are stacked onto Backstore physical tapes. When initially created, these Backstore tapes are filled to capacity. Over time, as the application tapes are released through tape management processing, these Backstore tapes become fragmented or partially used.
The RECYCLE utility reclaims unused space by merging the remaining active Virtual Volumes onto new Backstore tapes, allowing the input Backstore tapes to be scratched for reuse.
RECYCLE is a batch process that you can schedule manually or through automated job submission facilities. The frequency at which RECYCLE should be run depends on the rate that the Backstore tapes reach an unacceptable level of fragmentation.
