Deduplication & Replication

Faster backup windows, improved performance and the highest data security with SEP Deduplication, Replication and Encryption.


Utilize disk space more efficiently and reduce storage costs with the dynamic SEP deduplication solution.

SEP Si3 Deduplication is a scalable, high-performance, source-side solution that greatly reduces storage requirements.  Si3 delivers extremely fast restores due to the deduplication repository’s direct block-level access with zero file system overhead, eliminating any performance degradation during read operations. By using variable block sizes, you can compress more data into smaller footprints and maximize limited disk space.

Deduplication processes can be set by the main SEP management console to start during a backup or can be scheduled to occur at a set time on a regular basis. This flexibility allows you to accommodate different use cases for both deduplicated and raw data.

SEP software-based deduplication runs on any hardware, eliminating the need for expensive, hardware-based deduplication appliances.


SEP Si3 Replication is an easy and secure way to consistently replicate data between a main data center, a disaster recovery site, remote locations, and the cloud, providing redundancy for disaster recovery as well as reducing overall disk and tape storage requirements.

Maximize your existing infrastructure with SEP by creating off-site warm standbys and/or replicating data from any node to any other node. Since SEP is completely hardware independent, you can replicate to dissimilar hardware.
