Once data is written to magnetic media, the likelihood that it will stay written is high because magnetic traces tend to linger on disk and tape with a bewildering tenacity. That's good news if you're trying to recover the data, but it's less comforting if your goal is compliance, where the aim is to keep data for a given period of time and then destroy it beyond all recoverability. "Ever since Enron, no one wants to keep files around any more," says Diamond Lauffin, executive VP at Nexsan Technologies. This summer, the SATA array manufacturer announced a "secure storage appliance" called Assureon that digitally shreds files and data based on user-defined data disposition policies.

Features in this issue

  • Hidden threats to data

    Inadequacies in storage governance and weaknesses in data management may pose far less-visible risks to a company's data. To mitigate these threats, you must be aware of the impact and probability of these risks to reduce or eliminate them.

  • Safer SATA for nearline apps

    New SATA drivers tailored for nearline apps

  • Keep remote offices in sync

    With regulatory compliance, data protection requirements and the need to share data, remote office data can no longer be ignored. Wide-area file system products can rein in and protect remote data.

  • Will your disaster recovery plan work?

    No matter how many checklists a company creates, the number of disaster scenarios it considers or even how assiduously it backs up data, managers can't be confident in their firm's ability to recover data unless the systems have been tested thoroughly.

  • Better capacity forecasting

    There are two methods for devising storage capacity forecasts: quantitative and qualitative. By combining the two, you can develop practical metrics that will make more accurate forecasts.

  • Data grids for storage

    Data grids are used by the scientific community to access data resources around the world. Companies can use the principles underlying these global grids to link geographically dispersed sites.
