It should be ok I guess. Honestly, while I've worked for years with Legato, we always had enough of a tape budget, and it was worth the money to just do fulls weekly/monthly, and then incrementals each night. When we had to do a restore, it was worth the time ($$$) to not have to go through 5, 10 or more tapes to restore data. Can you do a simulation with 'dump' and do some actual measurements of the space savings of using the above method? That should give you actual numbers to work with. With those numbers, you should be able to go back to your boss and see what you could do. And honestly, if your users have such valuable data, then they should be willing to either a) pay for useful backups, or b) be able to re-generate the data themselves more quickly. But I know you're at a non-profit/univ environment, and time is always cheaper than $$$ at those places. With the cost of disks going down, it might be worth it to look into dumping the Legato setup, and instead putting some disks on a RAID controller, or even a motherboard with a bunch of SATA ports, a loading up some 1Tb drives (or whereever the sweet spot of $$$/cap is now) and then using 'rdiff' to make your backups. Heck, I've been buying old DLT IV tapes off Ebay for my home backups and tape library. Setup your own tape library. Yes, I know you said some of your options are fixed in stone. Then you can say you've done your best. Good luck!
