Post-installation checklist

    • Updating index_server and tape_server to Amanda server in the /etc/amanda/amanda-client.conf configuration file.
    • Add Amanda server to /var/lib/amanda/.amandahosts file
<Amanda Server> amandabackup amdump
  • Assign a password to the amandabackup user that was created the client install. This user on the Mac OS X client can be used for command line operations.

Adding Client file systems in ZMC

You can add the Mac OS X file systems/folders to the backup set using Zmanda Management Console. Use the Backup What page in the Zmanda management console to configure the Mac OSX client. You will need to specify the client name and the directories to back up.

Extended Attributes under Advanced Options in the Backup What page should not be selected for Mac OS X file systems. Extended attributes (such as Mac OS X resource forks) are backed up by default for Mac OS X and there is no option to turn it off.

Restoration to Mac OS X client

If you are restoring to Mac OS X client which has Amanda Enterprise client installed, Use Zmanda Management Console Restore pages.  The Restore What page explore window will display both resource forks and actual files in the window. The resource forks start with "._" characters. Both resource fork and the file name for complete file restoration including attributes.

Provide the Mac OS X machine where backups are being restored to in the Destination Host field in Restore Where page. Do not provide Destination User Name.

If you are restoring to a machine that does not Amanda client installed, ssh will be used for restoration.  An administrative user on Mac OS X is required for this method and must be provided in Destination User Name field in Restore Where page.  The following screen shows how to create "zmanda-admin" Administrative user on Mac OS X. Rest of the restore process is similar.

Step 1: Administrative user creation on MacOS X client
