Hi Bob,
Thanks for the reply and not for not being fully clear in my original post. I was was trying to explain if we set a schedule time for the job it would take the last backup and push this to tape. If that job happened to be an incremental it would be pointless as a monthly backup.
Enhanced Incremental sounds great and this was the original idea of making monthly backups, more time and effort would need to be placed in finding the best solution.
I'll work on the copylist method with scheduled jobs.
Thanks for your time
Sean
