| Retrospect Desktop is capable of backing up the machine it's running on, plus up to three other client machines. (You can purchase additional client licensesor, for larger groups, upgrade to Retrospect Workgroup or Retrospect Server.) This means you can use just one set of backup media and one schedule for several computers, instead of setting up a backup system on each one individually. All you have to do is install Retrospect Client on each client machine, add the clients to Retrospect's list, and select the volumes or subvolumes you want to back up on each one. The first part of the process is to set up the clients. Follow these steps: 1. | On a client machine, install Retrospect Client (the installer is included with Retrospect Desktop).
| 2. | At the end of the installation process, the installer asks you for a password. Choose something different from your standard Mac OS X passwordit need not be particularly secureand confirm it when prompted.
| 3. | The installer then asks if you want to enable a firewall exception for Retrospect. If Mac OS X's firewall is turned on, be sure to answer Yes.
| 4. | Click the installer's Restart button to restart your computer.
| 5. | Open the Retrospect Client application and make sure the On radio button is selected.
|
Repeat these steps for each client machine. That's ityour clients are now ready to go. The rest of the process happens on the server machine. To configure the server, follow these steps: 1. | Open Retrospect Desktop, go to the Configure pane, and click the Clients button.
| 2. | Click the Network button to display a window listing all the clients Retrospect can find on your local network (these are machines with Retrospect Client installed and turned on which are within the same subnetand not blocked by a firewall). You should have TCP/IP selected as the Network Protocol, and Mac OS X selected as the Type.
Tip If the machine you're using as a server has a firewall turned on, you must also add an exception for Retrospect. Go to the Firewall tab of the Sharing pane of System Preferences, click New, and choose Retrospect from the Port Name pop-up menu. If it does not appear in the menu, choose Other and enter 497 in the TCP Port Number(s) field. | 3. | If the client you want to add appears in the list, select its name. If the client does not appear in the list, click Add by Address and enter the IP address of the client computer; then, select the client's name in the list. Click Log In, and type in the password you specified when you set up that client. Also confirm (or modify) the name for the client as it will appear in the server's lists. Repeat this step as necessary for additional clients.
| 4. | After adding a client, the Client Configuration dialog should appear. (If it does not, double-click the client name in the Backup Client Database window.) On the General pane of this dialog, select Link Encryption if the client is connecting over a wireless network, or you want to add extra security to the data as it travels between the client and the server. From the Backup pop-up menu, choose Selected Volumes.
| 5. | On the Volumes pane, select all the volumes from the client machine that contain files or folders you want to back up. Click OK. Repeat as necessary for additional clients, and close the Backup Client Database window.
|
Now your clients are ready to be added to your backup scripts. Follow the instructions in Set Up a Duplicate Script (page 196), Set Up a Backup Server Script (page 200), or Set Up a Backup Script (page 203) to add clients to your scripts; the volume(s) you selected in Step 5 will appear in the Sources lists, and you can define subvolumes and selectors just as you did for items on the server itself. Tip If you're making duplicates of clients over the network, remember to choose a volumenot a subvolume!as the destination. You'll probably want to store each duplicate on a separate FireWire hard drive, or at least a separate partition of a FireWire hard drive, so that you can later attach that drive to the client machine if you need to boot from the duplicate.
