Drives are cheap, data is expensive.
I work in several labs where I have to give this advice, which some labs are smart enough to make an ersatz backup that we store somewhere (PI's house) as a cheap offsite. Even a partial recovery is great in the face of fire/flood/explosion, or the most common error: IT fucks it up and then says "oh well".
Hope someone has some copies and they can rebuild, what a nightmare.
