OES 2 offers both Novell Storage Management Services and services that are available as part of the SUSE Linux Enterprise Server 10 distribution.
Novell Storage Management Services (SMS) is not a backup application. Rather, it provides a standard framework and the necessary interfaces that can be used in developing a complete backup/restore solution. SMS helps back up file systems (such as NSS) on NetWare 6.5 SP8 and OES 2 servers to removable tape media or other media for offsite storage.
SMS is implemented as two independent components that provide functional abstractions:
Storage Management Data Requestor (SMDR) defines the API framework, provides remote connectivity, and abstracts the details of communication between servers.
Target Service Agent (TSA) provides an implementation of SMS APIs for a particular target. The TSA provides transparency by abstracting details of the specific service being backed up.
For example, various applications use the file system TSA to back up and restore NSS file system data and metadata (trustee assignments, file attributes, and name spaces).
In OES 2, the SMS API framework is available on SLES 10 so that there is a single consistent interface to back up file systems on NetWare, file systems on Linux, and Novell applications such as GroupWise and Novell iFolder. The API set has been enhanced to include new functionality for OES.
Most of the SMS coexistence and migration issues are of concern only to backup application developers. However, administrators should be aware that SMS-based applications must be used to back up and restore NSS file system data on OES servers. Although NSS is exposed as a Virtual File System-compliant file system, the Linux interfaces are inadequate to back up NSS file system attributes, rich ACLs, trustees, and multiple data streams.

Two SLES 10 services might be of interest.
This lets you to create a mirror of two block devices at two different sites across an IP network. When used with HeartBeat 2 (HB2), DRBD supports distributed high-availability Linux clusters. For more information, see

This is useful when large amounts of data need to be backed up regularly or moved to another server, such as from a staging server to a Web server in a DMZ. For more information, see
