Open source backup software vendor Zmanda Inc., among the first to offer customers a direct link between its backup software and cloud storage, is opening up its API for connecting backup software with cloud backup service providers to other vendors, including competitors.
CEO Chander Kant says Zmanda is sponsoring a new open source project called ZCloud, which offers an API to show how backup software connects to storage cloud providers to avoid duplicating work as more backup vendors offer the option. “Today every backup software has to talk a different language,” Kant said. “This will get rid of those idiosyncrasies and make interoperability easier.”
The subject of standard cloud APIs and interoperability is a hot one in the still-nascent cloud computing market. While some are already calling for or developing standardized cloud interfaces, others say it’s too early to establish industry-wide standards without quashing differentiation.
Kant points out that an API specifically for backup tools isn’t the same as industry-wide, homogenizing standardization. “This is how standardization is actually going to happen — not an overall set of specs, but specific ones based on specific use cases,” he said.
He added that while the API specifies common aspects of connecting backup to the cloud, there’s no reason a backup software vendor can’t add its own differentiators to the integration. “The API allows for discovery of the underlying storage clouds, keeping developers from having to repeat basic stuff,” he said. At this early stage, he says “most people are first trying to get to a basic level of functionality.”
