As has been said before, all data is stored in the database, so you don't need a year old backup file to see data from last year, however, what it will show you is if a specific piece of data changes, so if some info was changed a year ago, you'd need the year old backup, and any one from after the change to see the difference. However, is that very likely? Some areas, such as changing names, addresses, school groups / classes, are stored in the history within sims, so it's still possible to see that. Things where it might apply are grades stored with a result set (no history), behaviour records (easily deleted) etc.

Mmm... I could get it to allow you to move them, I assume to a network location?
Making Tea is easy, it's transporting that's the problem!!
Actually, that's not a bad idea, if you can somehow get it into a typical backup strategy, so it goes into Folders labelled by the week, then moved to a monthly one, so it's actually doing the rotation for you. With the option of deleting when it rotates or just to maintain the archive. Then it's up to the netman or whoever to just delete a folder rather than look through a list of files, which is what i do at the mo'.
