SnapServer 7.0 Administrator's Guide

Replacing a Server

The procedure described in this section for responding to a catastrophic event is general in
nature and may result in the loss of data. Should such an event actually occur, the exact
procedure to follow will vary according to environmental conditions. Overland Storage
strongly recommends that you contact a technical service representative before proceeding.
This section describes a worst-case scenario:
• The operating system has failed, (for example, due to a malicious attack to the root
filesystem), and you cannot access the server.
• The data has been corrupted and must be restored from tape.
• Technical support has deemed your server unsalvagable and provided you with a
new, unconfigured server.
Restoring Previous Server Settings to a New Server
After Technical Support has supplied you with a new server, you can restore the settings
from the previous server to the new server. Any third-party license keys you have not
purchased through Overland Storage will be lost. If you have installed data replication or
management utilities such as Snap EDR, you will need to re-install and/or relicense them
for use with the new server.
NOTE: If you are restoring Snap EDR Management Console settings, you must recreate the RAID
You will also need to reschedule snapshots as well reconfigure CA Antivirus.

3. Navigate to Maintenance > Disaster Recovery , select Recover System Settings and click
OK.
4. Click the Browse button and navigate to the SnapDRImage you made of the previous
server, then click Recover.
5. The server reboots and the settings are restored. To view the log, click the date link on
the Disaster Recovery page after the server has rebooted.
6. After restoring your server settings, rejoin the server to the Windows domain if
necessary.
7. Now you can replace your data from tape backup. If the backup doesn't retain
permission and ownership settings, you can restore these by selecting Recover Volume
Security Settings on the Maintenance > Disaster Recovery page.
NOTE: If you are restoring from any backup, you will need to recover the volume settings.

Cloning a Server

The Disaster Recovery process can be used to clone a server in order to apply the same
configuration to one or more servers. To clone a server:
1. Create a disaster recovery image on the source server (refer to Creating the
SnapDRImage and Volume Files).
2. Copy the disaster recovery files from the source server to a client.

and volume configuration that matches the DRI settings, then install and enable the
Snap EDR Management Console. As an alternative, you can first restore just the system
settings, install Snap EDR, and then restore just the Snap EDR settings.
