Each drive would contain volumes in two pools, one for full backups and one for incremental backups. For each client there would be two jobs, one backing up to drive 1 using pools "full1" and "incremental1" and another backing up to drive 2 using pools "full2" and "incremental2". The two jobs for each client would use two different schedules so that the jobs run on opposite weeks. A schedule for odd weeks of the month might use something like Run = Level=Incremental 1st,3rd,5th sun-sat at 21:00. Only schedule the daily incrementals, and then run the yearly full backups manually.
A year sounds like a long time between full backups. With 180 odd incrementals for each client you'll likely run out of disk space on a USB drive and defeat the purpose. With differential backups run every now and then, you could delete the no longer needed incrementals and consolidate space. > > Martin > ------------------------------------------------------------------------------ Come build with us!
