Virtualisation is now clearly established within manufacturers' IT systems, with very few yet to dip their toes in the technology. That's according to a survey by Vizioncore which found that 85 percent of enterprises have been using virtualisation for over a year.

There has been a change in the drivers however, 41 percent of those surveyed said that preventing application downtime and data loss were top of their priorities - just two years ago, said Vizioncore, the top response would have been server consolidation.

But if companies are getting quickly used to virtualisation, they haven't necessarily got to grips with all aspects of the technology according to Vizioncore. The company has been busily promoting image-based backup within virtualisation. The company has been running a campaign, Backup 2.0, devoted to explaining the technology.

"We found that the whole concept of image-based backup hadn't been explained," said Roger Baskerville, Vizioncore's VP for EMEA. "There are a lot of people still doing backup as the same way as they'd always been doing by using agents. Backup 2.0 is not a product, it's an education campaign to promote the benefits of using the new range and to show users that image-based backup is quicker than using agents."

Last month Veeam launched its own take on image-based backup and restore and Baskerville was amused at the technology behind the offering, claiming that Veeam took a long-winded approach.

"The way we do image-based backup is that if you kick off a backup on Sunday, then you do the same on Monday and Tuesday, then if you want to go back a few days, it's easy to do."

Baskerville said that Veeam's approach was slightly different. " They take a synthetic approach, where backup builds on backup. For example, Monday's backup is injected into Sunday Tuesday's into Monday and so on That means that if you want to go back to where you were a few days ago, it's not possible."

Vizioncore is going to build on its offerings - the company has a new version of its software out later this month. "We're going to be including a new feature - VMware has introduced a technology called Change block tracking (CBT). If we took a snapshot of the VM. In the past, we had to work out what blocks had changed. With CBT, we can now tell what blocks have changed. We're also going to include our own new technology, Active Block Mapping:. What this does, is to reduce backup window with CBT. We don't have to backup deleted files. Using the two technologies together mean that we'll really be able to speed up backup." said Baskerville.

"Our whole aim is to move to a more granular approach," added Baskerville. "That way if you want just one mailbox restored, we'll be able to do it."
