Tapes on the shelf will withstand those conditions (use a closed, sealable cabinet and toss a bag of silica gel decissicant in there every once in a while if need be [they recycle if you heat them up to 300F/150C]), but humidity that high is going to be nasty for equipment life in general and is going to be borderline for the tape drive while in operation itself. > I'd like to hear from people who have Been There and Solved > That.

I've dealt with more than one server room buildout, and I'm familiar with backup media interacting with environmental conditions, but climate control of the server room has always been a requirement (in the positive sense). The temperature you're describing isn't really a problem if you've got adequate air circulation through the racks, but the humidity is something else. -- -Chuck
