I'm looking for advice on how to backup a data set of 3+ TBs and growing without breaking the bank. The data will soon live on a RAID, but we want an offsite backup set and one continuously updated backup set onsite.
Are tape drives the way to go? It looks like an LTO-4 drive can handle the volume relatively few tapes, but the drive itself is really expensive ($4500+), plus the cost of tapes, which seem to be about $90 per 800/1600GB tape.
Are hard drives out of the question? You can get external firewire HDDs for about $920 per 3TB set, but I have a feeling that by professional standards, HDDs are not acceptable for important data backups. Is that true?
We have Retrospect and are moving to BRU, so it's really just a question of which hardware will give us the best bang for our buck. Any advice would be greatly appreciated.
