Have you considered backing up your data in the Cloud?

 The Cloud is where today’s end users expect to store and share their digital content – after all, they already use iTunes and Dropbox. What’s more, cloud services generally make sense for mobility initiatives and those involving non-mission-critical data. And cloud storage is easy to set up, right?

Well, not exactly. At one time, it meant simple drive substitutes like SkyDrive and iDisk file hosting services, but today there are endless solutions on offer as vendors respond to diverse consumer and business needs – and that’s created confusion. Let’s face it, there’s a world of difference between using bulk cloud storage as an alternative to off-site tape or online data repository for distributed apps – as opposed to having a cloud service replace your entire backup infrastructure: software, hardware, tape library and staff.

Business continuity is both helped and challenged by today’s top tech megatrends

, failure is not an option. Not surprisingly, organisations have made it a high priority to develop and implement reliable business continuity plans to ensure that IT services are always available to internal users and outside customers, says Bob Violino on CSO Online.

But recent technology developments and trends, most notably server and desktop virtualisation, cloud computing, the emergence of mobile devices in the workforce and social networks, are having an impact on how enterprises handle IT business continuity planning and testing. Much of the impact is for the better, experts say, but these trends can also create new challenges for IT, information security and risk management executives.

Top five issues in analysing backup and disaster recovery costs

The backup target: Tape sucks for recovery, but it’s great for archives. For every 20 terabytes of production data with a 2% change and 3% growth rate, and using a traditional backup operation of daily incremental and weekly full backups, you need to manage 110 terabytes of tape media. Therefore, a shop with 100 terabytes would need 550 terabytes of tape (100 x 110 = 550). Your goal should be to include tape as an archive storage tier so you can minimise the need to recover from tape.
