Epsilon is the patented iOra compression engine that is the core component of efficient replication operations. Irrespective of the network connection speed, minimising data that needs to be sent over the network to execute a phase of replication is essential. Compression of updates is particularly important where the network connection is challenging or where the end user is operating at the edge of the corporate network. The world-leading cross file compression technology ensures that data replication over the network is highly efficient. In many of these instances, Epsilon becomes an enabler for introducing new data-sensitive applications to remote users who would not be able to access data without efficient data transport. iOra Epsilon compresses to 99.9%.
