SnapServer NAS Software Solutions
SnapServer NAS Systems support a wide range of data sharing, data protection and replication solution software designed to be
compatible with today’s computing environment in distributed enterprises and small businesses.
4.1
GuardianOS
Every SnapServer NAS System is delivered with GuardianOS that combines file-‐level (NAS) with block-‐level (iSCSI) data on a single
device to provide a simple and flexible solution ideal for any storage infrastructure. In addition to its unified storage architecture,
GuardianOS offers seamless scalability for scalable SnapServer NAS systems, centralized storage management, and a comprehensive
suite of data protection tools ideal for consolidating data and simplifying management to reduce storage total cost of ownership
(TCO).
4.2
Replication with Snap Enterprise Data Replicator
4.2.1
Snap Enterprise Data Replicator (Snap EDR)
Snap Enterprise Data Replicator (Snap EDR) 7.2 provides a powerful, high-‐performance data replication and protection solution, with
a comprehensive set of data management, movement, and backup capabilities. Administrators can remotely move files between
servers; replicate data from their remote offices to a central server where it can be protected with established backup and restore
procedures; or automatically distribute data from a central server to multiple remote offices. With Snap EDR, the administrator can
implement enterprise-‐wide data movement, backup, disaster recovery, and compliance operations from a single location.
Snap EDR 7.2 is an option to GuardianOS 5.0 or greater and is licensed by functionality of Snap EDR (EDR Express or EDR Standard) as
well as by class of platform (Workgroup, Departmental and Non-‐SnapServer NAS Systems). Each system participating in Snap EDR
replication or backup requires a separate Snap EDR license whether it is a SnapServer NAS, Windows, Solaris, Linux or MAC OS X
(10.6 or below) system.
Snap EDR 7.2 can be used to replicate data between any GuardianOS-‐powered SnapServer regardless of GuardianOS release
provided that Snap EDR is the same version for all SnapServers participating in the replication.
4.2.1.1
Snap EDR Standard and Snap EDR Express
4.2.1.1.1
Snap EDR Standard
Snap EDR Standard Edition includes all functionality, including remote backup, as well as one-‐to-‐one, one-‐to-‐many and many-‐to-‐one
replication. Snap EDR Standard can be positioned not only for disk-‐based backup and disaster recovery but also for data distribution
and versioned disk-‐based backup with the advanced backup functionality included over EDR Express.
Snap EDR Standard is licensed by class of SnapServer NAS Systems as well as by client operating system (for non-‐SnapServer NAS
systems) as follows:
-‐
Snap EDR Standard -‐ Windows / Mac OS X / Linux / UNIX
1
-‐
Snap EDR Standard -‐ Workgroup
-‐
Snap EDR Standard – Department (Included with the SnapServer DX2)

Snap EDR 7.2 supports Solaris as the only UNIX platform. Refer to the data sheet for specific versions.
