So, the lab I'm in recently had a scare with an external network HD that died and almost lost all of the data. Luckily, our tech folks could save it, but we may not be so lucky next time, which has prompted me to look into various backup options.
The problem: we have 3TB of data to back up, expanding rapidly. A good experiment day can generate 20-400 GB of data, depending on what we're doing, and overall I'd estimate we're generating about 1 TB a year.
So how to back it up? We're fine with only backing up every month or so, since most of the day-to-day work takes place on our laptops which have various typical-user backup systems; the large storage is mostly for extremely large raw data files.
So far, I've figured out that neither blu-ray writers nor online backups are feasible, simply due to the large volume of data rending each prohibitively expensive.
Naturally, I've been looking at tape drives. Are the tapes re-writable? How much re-writing can they take before degrading? Are such systems generally worth it, price-wise? Do they typically come with software that helps you, or are you pretty much on your own?
Are there any other systems for large-volume data backup?
