How to store huge amounts of data in a smaller box

Having all the space you need for storage is great, but how do you actually find something when you need it? I still have a football from my last game as a stellar 12-year-old quarterback. (Unfortunately, my mental aptitude continued to flourish while my physical size and abilities went straight into retirement.) Don't ask me to produce the ball; I know it's in the attic, but I'll never find it. Think of the giant reams of unstructured data you have as your attic. Can you find your football? I doubt it. We can shove hundreds of terabytes that used to take up more space than the state of Rhode Island into something the size of a four-foot box. Now we have something the size of the Grand Canyon, and we've filled it up with stuff. While we know everything is in the Grand Canyon, it's mostly useless because we can't actually find anything we need. Hey, where's that check I wrote to Storage Swinger Review? We've placed more value on getting stuff in than on getting it out, and that's going to hurt us. Finding something is harder than...

Features in this issue

  • Use mainframes for backups

    You can put that big iron sitting in your data center to better use by using it to back up open-systems data, too. The net effect is a streamlined backup and disaster recovery operation.

  • Any-point-in-time backups

    by  Brad O'Neill

    Continuous data protection captures changes at a file- or block-level as they happen, and provides running recovery journals for all historical data states. This shifts data protection to a more flexible any-point-in-time framework.

  • Make tape libraries work with all platforms

    If tape libraries could share IT resources and data across all processing platforms, data center complexity and cost could be dramatically reduced.

  • Sizing up VTLs

    Virtual tape libraries present disk as tape, so backup apps can perform backups as usual, regardless of the physical backup infrastructure. Learn about hardware and software VTLs, the benefits of each and how they might fit into your backup operation.

  • Does host-based replication still make sense?

    Host-based replication is a mature technology, but it's often not considered an option for architectures that support quick recovery. But there are many cases where a host-based option may fit.

  • VTL remedies backup woes

    VTLs remedy tape bottlenecks...

  • Cisco's switch-based backup

    Serverless backup can take the load off servers and ease network traffic. Cisco uses Xcopy on its MDS 9000 switch for serverless backup; see how it compares to other methods and products.

  • Used tape sales on the rise

    by  Alex Barrett

    Pre-used tapes are becoming a popular and inexpensive trend among IT professionals. Become familiar with the possible risks of using used tape in your environment.

  • How disk has changed backup

    Inexpensive disk has spawned a variety of disk-based backup alternatives. But with more choices comes greater complexity compared to the days when you simply had to choose a backup application and tape library. Backup guru W. Curtis Preston explains the advantages of using disk for backup, including virtual tape libraries and disk-as-disk backup targets, and discusses the pros and cons of alternative disk-based backup methods.
