For one thing, I think you seriously need to look at backup up to offline hard drives, instead of tapes. Unless you really want/need to archive the tapes for seven years
Well, the scientists are talking longer than 7 years so HDs just are not going to cut it
I'd be hard pressed to find a tape drive that could read any tape I've written that long ago.
We back up to backup servers, then, every couple of weeks, I run rsync backups (well, we have a locally-rolled system to run the rsync) onto offline drives - in our case, I swap large drives into an eSATA drive bay. When I'm done, they go in the fire safe.
That's what I'd prefer to do :-)
You probably need to look at how you identify things first to see if any existing archive approach maps onto that well enough or has a searchable online index so you would know which tape to restore when someone asks for old data.
Personally I always think of backuppc first for backups because it can hold so much more online, but it isn't great at archiving. You can make a standard tar image out of anything it has stored, but for anything but the latest run it would take some command line options or selecting it through a web browser.
