Backing Up Server and Volume Settings 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. 118 SnapServer Administrator Guide
