Do Large Corporations Need Tape?
I am dealing with a situation where I have to gone from a tapeless TSM environment to the standard TSM tape model and I have to wonder why you would use tape when you have multiple data centers? If you have multiple data centers why not backup to disk and replicate the data on disk to a disk solution at the alternate DC? I did this with Data Domains and it made life so much easier. Multiple DR tests showed it was efficient and successful, of course this also utilized deduplication so disk usage and costs didn't get out of hand. So I ask why is any large corporation still using tape?
