The TAPECOPY process, when using either ALL or BACKUP keywords, only copies full tapes. If copies of partial backup tapes are desired, use the following process:

• Issue one of the HOLD commands to stop backup for all hosts running backup. The following HOLD commands cause the data set backup tasks that have tapes mounted to demount the tapes at the end of the current data set.
  • HOLD BACKUP holds all backup functions.
  • HOLD BACKUP(DSCOMMAND) holds data set command backup only.
  • HOLD BACKUP(DSCOMMAND(TAPE)) holds data set command backup to tape only.
• A LIST TTOC SELECT(BACKUP NOTFULL) lists the tapes that are not full. This list also shows which tapes do not have an alternate tape.
• A DELVOL MARKFULL is used for those tapes that you do not want extended after the TAPECOPY is made.
• A TAPECOPY OVOL(volser) is used for those tape volsers that do not have an alternate volume indicated in the LIST output.
• When the copies are complete, the corresponding RELEASE BACKUP command issue option can be used (on each host that was held) to allow backup to be usable.
