My thought is to move the hard drive backups to a single day cycle and use the tapes for a 14 day cycle. That way I never have to worry about disk space as there is always only a single day of backups stored on the disks. This also means that the previous nights backups are stored securely off-site as soon as they are migrated to tape. >>> >>> So basically what is the best configuration for doing this?

Keep your File and Job Retention >= your Volume retention. Your disk pool will have Volume = 7 days. Your tape pool, 14 days. > The big benefit that I would see to copying > is that if I need to restore anything within the first 7 days I can simply restore it from the server > without having to go get a tape and load it. What job completes faster, a migration or a copy? I say there isn't much difference. Try it. See. -- Dan Langille - http://langille.org/ |
