Backing Up Server and Volume Settings

118 SnapServer Administrator Guide

The SnapDRImage File and the Volume Files

Details on the SnapServer disaster recovery files and the information they contain

are as follows:

• SnapDRImage — The SnapServer disaster recovery image saves server-specific

settings such as network, RAID, volume and share configuration, local user and

group lists, and EDR Management Console settings (if applicable). There is one

SnapDRImage file per server, residing on the root directory of the first volume at

the following path:

\\server_name\volume_name

Note The SnapDRImage file is in binary form and can be safely used only with

the SnapServer Disaster Recovery tool. Other tools will not work and may

compromise the integrity of the file.

• Volume-specific files — These files, named backup.acl, backup.qta.groups, and

backup.qta.users, preserve volume-specific settings such as ACLs, extended

attributes, and quota settings. One set of these files exists per volume, residing at

the following path:

\\server_name\volume_name\.os_private

Caution The Create Recovery Files option in the snapshot feature automatically

updates the volume-specific files when the snapshot is taken. If you do not use

snapshots to back up a volume to tape, you must manually regenerate these files

whenever you change ACL or quota information to ensure that you are backing

up the most current volume settings.

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

Maintenance > Disaster Recovery page. This DRImage should be

created after server configuration is complete, and 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 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.
