I thought this would be an easy problem to solve, but I haven't found a decent solution after a bit of looking. I have a huge file, say 73GB. I need to dump it to tapes that have a capacity of about 33GB each (but there is hardware compression, so there is no exact capacity). If the file would fit on a single tape, I'd just use good 'ole dd(1). I figured, heck, somebody is _bound_ to have written a simple utility that, say, reads from a pipe and writes to tape (or vice versa), and prompts for a tape switch when it hits end-of-tape. But alas, I cannot find such a beast. Using dump, cpio, etc is not really an option. I need to be able to later read the data from tape into a pipe without it hitting disk. Anybody have bright ideas?
