Disaster Recovery
Disaster recovery entails creating the files you need to recover a
SnapServer’s configuration information, such as network and RAID
configurations, as well as volume-specific information, such as ACLs and
quota settings.
It also includes what to do if all access to the data on a SnapServer is cut off
due to a hardware or software failure. Focus is placed on the procedures
for:
• Reinstalling the SnapServer operating system
• Restoring the server to its original configuration with data intact
These files are then used to restore any SnapServer to its original state. The disaster
recovery feature can also be used to clone one server to another by restoring the
disaster recovery image from one server to another server.

Backing Up Server and Volume Settings
In addition to backing up the data stored on the SnapServer, you may also back up
the server’s system and volume settings. The
Maintenance > Disaster Recovery
screen allows you to create the files you need to restore these settings:
• Server-specific settings such as network, RAID, volume and share configurations,
local user and group lists, snapshot schedules, and EDR Management Console
settings (if applicable).
• Volume-specific settings such as ACLs, extended attributes, and quota settings.
