Backing Up Server and Volume Settings
102 Snap Server Administrator Guide
The SnapDRImage File and the Volume Files
Details on the Snap Server disaster recovery files and the information they contain
are as follows:
•
SnapDRImage — The Snap Server 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 Snap Server 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 Snap Server. 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.
