The dedupe technology employed in Arkeia Network Backup 9.0 provides source-based dedupe, which dedupes data before it is sent over the network for backup and archiving, Evans said.
The technology employs progressive deduplication, which Evans said improves on the variable-block dedupe commonly used by many vendors. With variable-block dedupe, the boundaries between blocks of data are set by the data itself. However, with Arkeia's progressive deduplication, the boundaries between blocks of data are set by the dedupe software for maximum performance and a higher dedupe ratio, he said.
The new dedupe feature is also application-aware and content-aware, Evans said. "We're able to compress a file better by knowing the type of data that's in the file," he said. "So whenever our software encounters, say, a PowerPoint file, it knows exactly the right block level to get the maximum compression ration. Different files compress better with different block sizes."
Arkeia in November will also recruit solution providers to help build a database of file types and their optimum block size for dedupe purposes with the release of its new "Profiler."
Profiler dedupes test files using a variety of block sizes to find which is best, and then updates the Arkeia software with the information, Evans said. "It's important for us to get this data," he said. "We don't have access to every data type in the world. We don't want one guy just guessing what is best."
