How to Prepare for Backup Software Recovery

Before you can restore Backup configuration files and/or indexes, you must reinstall the Backup software from the original media on the damaged system.

To reinstall the Backup software, follow these instructions:

1. Replace the damaged disk if necessary. Make sure the replacement disk is as large or larger than the original disk.

2. Use the saved disk partition information to re-create the disk partitions with the same structure as the original disk.

   See "Disk Information".

3. Use the output from the disk information command to make a filesystem for each raw partition that you plan to recover, then mount the block partition. (Backup does not initialize or create filesystems; it recovers data into existing filesystems.)

4. Use the appropriate command to format the replacement disk.

   For SunOS and Solaris systems, use newfs or mkfs.

5. Reinstall the Backup software, using the original software and accompanying documentation.

   On a Backup client, you only need access to the Backup binaries. You can run Backup from the /usr/sbin/nsr directory or NFS-mount the binaries from another system running Backup. Refer to the appropriate Solstice Backup 5.1 Installation and Release Notes for detailed instructions. Reinstall any Backup patches you had installed prior to the disaster.

   Backup servers only - You do not need to reload the license enablers if the /nsr/res directory (configuration files) still exists. If the /nsr/res directory was destroyed, the license enablers are recovered when you recover the configuration files.

6. If you had a link to another disk that contains the Backup indexes and configuration files (/nsr) or any other Backup directories located on another disk, re-create it now.

   Backup servers only - If you back up to an autochanger and want to use it during the remainder of the disaster recovery, add and configure the autochanger with the jb_config command after installing Backup. See "Recovery with Autochangers (Jukeboxes)" for more information.

   You can also use the following method to access the Backup binaries for recovery. If you have another system running Backup that is like the system being recovered on the network, you can NFS-mount the Backup binaries to the damaged system.

   For example:

   # mount venus:/usr/etc /mnt # /mnt/recover -s server -q recover> add / recover> force recover> recover

   If this system is a server, continue with the disaster recovery by restoring the Backup indexes and configuration files. See "How to Recover Backup Indexes and Configuration Files " for instructions.

   If this system is a Backup client or storage node, see "How to Recover Backup Clients and Storage Nodes" for instructions.
