Restoring Original Server And Volume Configurations - Overland Storage SnapServer Administrator's Manual

SnapServer 7.0 Administrator's Guide
Creating the SnapDRImage and Volume Files
Creating a SnapDRImage that covers the scope of your server's configuration is essential to
a successful disaster recovery operation. Create a disaster recovery image on the Disaster
Recovery
can be used to recover the server or a replacement server to the configured state.
Before you create the disaster recovery files, make sure you have completed the following
activities:
• You have completely configured the SnapServer. If you subsequently make any major
changes to the configuration of your server, you must repeat the procedures described
in this section to have an up-to-date SnapDRImage.
NOTE: You may want to record, in an off-server location, the following information about the
• You have devised and implemented a data backup strategy. It is recommended that
you make a backup of your system regularly, from the root of the share for each
volume, and store it in an off-server location. This ensures that the most current data
is backed up and available for use with a disaster recovery.
Use the following procedure to create and secure the disaster recovery files:
Step 1: Create the disaster recovery files.
Navigate to the Maintenance > Disaster Recovery page. Select the Create Recovery Image
button and click OK to create the SnapDRImage file and the volume files in a single
operation.
Step 2: Copy the files to a safe place off the server.
Once the recovery image has been made, click the Download Recovery Image button to
download the SnapDRImage file to a safe location on another server or backup medium.
(See The SnapDRImage File and the Volume Files for file names and paths.) This
strategy ensures that if the filesystem on the SnapServer is corrupted, the image file will
be available to restore server settings.
The DRImage is also automatically placed in the root of the first user volume. These files
will be copied to tape as part of your regular backup procedures.
Step 3: Take no action regarding the volume-specific files.
These files will be copied to tape as part of your regular volume backup procedures.

Restoring Original Server and Volume Configurations

To restore the original configurations to the server, two separate operations are required
and they must be run sequentially. After you start any of the recovery processes, you will
see the Disaster Recovery Status page.
CAUTION:
restricted to this page so that the recovery operation will not be interrupted.
NOTE: You can go to
10400317-001 10/2011
page. This DRImage should be created after server configuration is complete, and
configuration of your server: (1) the server name; (2) the number of RAIDs; (3) the
number of volumes; and (4) the size of each volume. If the disaster recovery fails,
having this information may be useful in recreating the original configuration of the
server.
Do not try to navigate back from this page during the recovery process. Activity is
