Why would I trust my offline storage disaster recovery and archiving to a tape solution? Is tape recovery reliable?
It's been used for years, and many companies have successfully recovered from tape. Yes, many of have failed. However, I would say that MOST of the failures have been with low-end tape drives that should have never been purchased in the first place. I cannot say that all tape is good or bad, but I can say that some tape drives should have never been put on the market. (And no, I'm not going to say which ones. Can you say Oprah and the meat industry?)
In my experience, any reliability problems with tape can easily be remedied by having multiple copies of the data. This is not economical in disk environments, but it's pretty easy to do with tape.

A lot has been made recently of disk's emergence as a viable option for backup and recovery. While many of the virtual tape systems, disk libraries and software based disk-to-disk technologies are in their infancy, they're drawing a hard look from many users and analysts in the industry.
The fact is this: using tape for backup in today's business world poses problems. According to Arun Taneja, founder and consulting analyst with the Taneja Group, if you aren't considering disk as a primary backup option today you will be within the next 18 months.
In this interview, Taneja explains who should be evaluating the technologies and why. And he offers a preview of his upcoming presentation on next-generation backup at the Storage Decisions conference later this month.
