New backup techs need new thinking

New technologies tend to bring some new baggage even as they solve old problems. Many of the newest storage technologies target backup, the perennial pain point for storage managers. Data protection techniques have made great strides in addressing this most troublesome part of storage administration, but with the cures come some side effects. Applying a new backup technology is often more akin to plugging holes in a leaky dike than actually improving the process. And that's not surprising given the runaway data growth experienced by nearly all companies. Fixing something that's broken is--as Martha Stewart would say--a good thing. But it's an even better thing to adjust the rest of the environment to the new technology. Vendors have been churning out new stuff designed to fix backup. Virtual tape libraries (VTLs), continuous data protection, wide-area file systems (WAFS) and single-instance storage are just a few examples. Disk-based backup technologies have already become an $8 billion market, according to a recent IDC study. ...

  • Tricky backup for SharePoint

  • CDP: Look before you leap

    Some pundits have postulated that continuous data protection (CDP) will replace backup. But is that just new technology hyperbole or is CDP a must-have technology?

  • Backup-to-disk performance tuning

    Disk-based backup can lower costs, reduce complexity and add scalability. But to achieve top performance, you'll need to do lots of benchmarking and watch for poorly configured production storage.

Columns in this issue

  • Backup best practices are always evolving

    Some new advances in backup, such as virtual tape libraries, represent evolutionary enhancements to the traditional backup process, while others like continuous data protection and single-instance storage are potentially far more transformational.
