The Tape Debate
Get rid of tape? I don't think so. But that's what Synopsys is considering with the installation of new storage appliances and software from Data Domain, EMC, and Network Appliance.
Disclosure: I have friends that work for Network Appliance, so I may take gratuitious shots at them for the sake of humor
While you might look forward to having Jennifer come install a Network Appliance SAN at your site, it might not be worth giving up your tape system. After all, if there's a fire near your building and the fire department comes, you might experience delays as she and the rest of the females nearby stop working stand in awe of those strong fireman. How do you back up your data when a 2TB appliance is sitting half installed and you've already arranged for the removal of your tape system to the local eBay retailer!?!?!?!
And even if you get the appliance installed with Data Domain's de-dupeing software and get a 20:1 compression, how do you get those bits back when you need a restore. Bringing back every 20th bit on a SQL Server database just isn't practical.
All fun aside, archiving data requires lots of space. And coming up with a scheme to avoid every day fo the last 7 years is possible, but not easy to manage necessarily. You might get by with every day of the last week, end of months, and then end of years, but who knows. Plus there's always the chance of an audit for some snapshot on the day before or after a close of month or quarter.
I do think that using disk storage can help reduce your tape needs, but over time, especially with more legal requirements to keep data records for long periods of time, a tape system is still probably an essential tool for most companies.
