Indeed not.  No sarcasm, whatsoever, was intended.  For long-term
storage, I wouldn't trust 4mm tapes, or any other very high-density
media like that.

Well, backing up 2GB on such tapes isn't too bad.  It all depends upon
how valuable the data is, and how long you plan to store it.  To take
this a step further, for small amounts of data, such as backing up
EPROMs, etc. in older computer systems, for preservation purposes, I'd
recommend using punched mylar tape.

As an aside, those 4mm drives certainly deprive computer operators of
fun jobs - nothing like getting paid to sit around and wait for each
magtape to fill up (having to work 3 minutes out of each hour, and
hacking for fun during the other 57 minutes, isn't a bad deal!).

It's still relatively new.  Give it time to fail.  :-) :-) :-)
