I currently have 3 IBM servers that have data to be backed up and will most likely be adding two more in the next 12 months. The total amount of data being backup up now 350gb and I can easily see this growing to over 500gb in the next year. I have looked at an IBM drive that has a 800gb native capacity but the sticker shocked nearly killed me at almost $5000. What tape drive manufacturers do you prefer? I realize that a lot of them are really Seagates relabeled.
