We have a Sony 9000 backup tape drive that uses 4mm DAT tapes that are rated 12/24gb dependent upon compression. Our server has just hit about 17gb and is now requiring us to use a 2nd tape for nightly backups. If I want to avoid the 2nd tape - can I buy 'bigger' tapes or will I need to go for a new tape drive? What's the next size up? Is there a better alternative to DAT tape backup? We've looked into 'live' over the internet type backups and they are just too expensive.
Thanks in advance,
