I work in space science. Those issues are exactly the reason I beat on our people that they can't be complacant and leave data on old tapes (which they will do, given half a chance, as it's cheaper to ignore old data). NASA policy _now_ is that budgets for new projects must cover curating data from their predecessors. Data can be migrated to new media fairly easily if you do it as you retire the old stuff, but coming back to it 10 years later is an exercise in pain - because the hardware to read the media often doesn't exist. As an example of this, I had someone show up a few days ago with an old RLL hard drive that has material on it they may want. We have no way of connecting it up to read it. Another scientist has a garage full of 9 track tapes and some vague ambition to migrate the data and another group have 1200 Exabyte cartridges full of ESA data which they claim will be readable for the forseeable future, despite the only exabyte drive left in the organisation being faulty. To make matters worse on the Exabyte front, the data format is nonstandard, using a windows program (only runs on W95) which reads entire tapes at a time. It's not simply a matter of copying what's on the tapes to LTO6. AB ------------------------------------------------------------------------------ Is your legacy SCM system holding you back?
