Disaster Recovery
This chapter explains how to create the files you need to recover a Snap
Server’s configuration information, such as network and RAID
configurations, as well as volume-specific information, such as ACLs and
quota settings.
It also discusses what to do if all access to the data on a Snap Server is cut
off due to a hardware or software failure. Focus is placed on the procedures
for (1) reinstalling the Snap Server operating system; and (2) restoring the
server to its original configuration with data intact. The final section
describes how to use these files to restore any Snap Server to its original
state.

Backing Up Server and Volume Settings

its system and volume settings. The
Maintenance > Disaster Recovery
screen allows
you to create the files you need to restore these settings: (1) server-specific settings
such as server name, network, RAID, volume and share configurations, local user
and group lists, and snapshot schedules; and (2) volume-specific settings such as
ACLs, extended attributes, and quota settings.
