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.

Yes, I can probably upgrade. I am reconfiguring most of it anyway so I might as well while I am at it. 

Good writeup. Would you recommend that I use copy over migration? I have space to store up to 7 days of backups on the server hard drive. If I understand it correctly, I can copy those jobs to tape and keep them for an additional 7 days if I want (for a total of 14 days) and still restore individual files from them even after the initial 7 days is up and the volumes on the server have been recycled/purged, correct? 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?
