I have reached the point where I am about to start production of animation files (and matching sound files). What is the best solution to the storage problem? (1) Buy a second, large hard drive? Expensive, and would it only be a temporary solution? And what if it crashes? (2) Bernoulli disk drive? Sound attractive; are there any snags? (3) 25MB floppy drive? Any snags here? (4) Tape backup drive. This is attractive, because inexpensive. I have no experience whatever of such systems. Can one break up the back-up operation into separate files which can then be retrieved individually? If so, would this require a linear search, or would the tape have a table at the front end listing what has been downloaded onto it? I realise, of course, that the transfer process would be slow, but this wouldn't matter, since transfer operations would only be required infrequently. (5) I heard somewhere that there is a VCR backup system (by Omnitronics?) which uses video tape, and which is very inexpensive. Anyone know anything about this? Stephen
