Half of the 535 respondents work in organisations with more than 1000 employees, and nearly 60% manage somewhere between 6 and 75TB of data.
52% said they were considering the use of cloud storage services, most commonly as a way of providing offsite disaster recovery.
Other prominent reasons included replacing or supplementing tape (perhaps they should look at IBM's prototype high density tape system), reduced costs, decreased data centre footprints, and increased storage capacity.
But 75% of respondents expressed concerns. The most common (30%) was security.
Other concerns included reliability, cost and scalability.
Respondents seem aware of the need for bandwidth to support cloud storage: of those planning to use cloud storage, 31% expect to dedicate 1.6-30Mbps to accessing it, and another 15% reckon on 31-130Mbps.
"From our latest survey, we know that many of our customers are considering cloud storage to keep pace with rapid data growth and reduce internal IT costs," said David West, vice president of marketing and business development for CommVault.
"Still, they're worried about security, complexity and reliability, especially since protecting their mission-critical data remains of paramount importance. To that end, CommVault is working diligently to ease their concerns and ensure that customers will be able to reap the maximum benefits of sound, secure and seamless cloud storage strategies," he added.
CommVault provides systems for data management and protection.
