We are migrating from BE to DPM 2012. I'm trying to configure DPM 2012 for both short term & long term protection - both using tape (stand alone drive). The goal is:
- Daily backups (Mon, Tue, Wed, Thu) - 2 weeks retention
- Weekly backup (Friday) - 4 weeks retention
- Monthly backup (last weekly backup) on every month - 15 m onths retention
I've configured the short term protection for daily and weekly backups. Monthly backups are configured under long term protection. Daily and weekly backups are working as expected. However when it comes time for the Monthly, the DataSet copy jobs are failing. As I understand it, DPM is expecting another drive to copy the weekly backup tape.
How I can achieve above goals ? Backup to disk is not an option.
